How can a graphing calculator help you find the solution to a system of equations? Consider this system:
5x - y = 35
3x + y = -3
a. First graph the system in a standard window. Can you see the solution on your screen?
b. To find the solution you will need to change the window on your calculator. Discuss with your team what maximum value, minimum value, and scale
you should use for the 2- and y-axes in order to see the intersection. After you have decided, check your conclusion on the graphing calculator.
c. Use a "trace" function on your calculator to find the solution from the graphs. Then solve the system algebraically.
d. Discuss the two methods with your team. Explain which one your team prefers and why.

If Hawa pays a flat cost of $51.50 per month and $3 per gigabyte and she wants to keep her bill at $64.10 per month. then the equation which can be used to determine gigabyte is 51.50+3x=64.10 and the number of gigabytes of data Hawa can be used is 4.2 gigabytes

Given,

The flat cost = $51.50 per month

The cost per gigabyte = $3

She wants to keep her bill = $64.10

Consider the number of gigabytes used as x

Then the equation is

51.50+3x=64.10

3x=12.6

x=4.2

Hence, if Hawa pays a flat cost of $51.50 per month and $3 per gigabyte and she wants to keep her bill at $64.10 per month. then the equation which can be used to determine gigabyte is 51.50+3x=64.10 and the number of gigabytes of data Hawa can be used is 4.2 gigabytes.

Step-by-step explanation:

Answer:

x = 16

Step-by-step explanation:

The dimension of the triangle whose perimeter is 18 feet will be 4 feet, 6 feet, and 10 feet.

The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.

The perimeter of the triangle is determined by adding together all of its sides.

Let 'x' be the first side of the triangle. Then the second and third sides of the triangle will be (x + 2) and (2 + x + 2). Then the equation is given as,

x + (x + 2) + (x + 2 + 2) = 18

3x + 6 = 18

3x = 12

x = 4

Then the dimension of the triangle will be given as,

x = 4

x + 2 = 4 + 2 = 6

x + 2 + 2 = 4 + 6 = 10

The dimension of the triangle whose perimeter is 18 feet will be 4 feet, 6 feet, and 10 feet.

Answer: 20

Step-by-step explanation:

Everything within the parenthesis gets an exponent of two, so you should have (x^2+y^2).

After this, you plug in the 'x' and 'y' given, so the next part should look like (2^2+(-4)^2)

After step 2, do 2*2 and -4*-4 (exponents ask you to multiply numbers by a specific amount. In this case, both numbers are multiplied by themselves 2 times).

A negative times a negative is a positive, so -4^2 or -4*-4 is 16. 2^2 or 2*2 is simply 4.

Add 4 and 16 together to get your final answer of 20.

Answer:3.2

Step-by-step explanation:

The least ton is 4 ton and the greatest ton is 8 ton.

Given an approximation for the weight of African bush elephant.

If we take x as the weight of an African Bush elephant, then

4.4 < x < 7.7.

We are asked to find the least and greatest weights rounded to the nearest ton.

The least weight is 4.4. But when rounded to the nearest ton, we can consider the least weight at 4 tons.

Likewise, the greatest weight is 7.7 tons.

But the greatest weight rounded to the nearest ton = 8 tons

We rounded 4.4 to 4 because the decimal digit 4 is less than 5.

Also we rounded 7.7 to 8 because the decimal digit 7 is greater than 5.

Answer: -6/7

Step-by-step explanation: combine like terms.

Same signs; add, different signs; subtract.

The length of the hypotenuse of the triangle is; AB = 2√106 ≈ 20.591

The Pythagorean theorem says the square of the hypotenuse is equal to the sum of the squares of the legs. Thus;

For median AM, we have;

AM² = CM² +AC² = (BC/2)² +AC²

For median BN, we have;

BN² = CN² +BC² = (AC/2)² +BC²

The sum of these two equations gives us;

AM² +BN² = BC²/4 +AC² +AC²/4 +BC² = (5/4)(AC² +BC²)

AM² +BN² = (5/4)(AB²)

Thus, we conclude that the length of the hypotenuse of triangle ABC is;

AB = √(4/5(AM² +BN²))

AB = 2√((19² +13²)/5)

AB = 2√106 ≈ 20.591

4.92*10^5 times the annual flow of the Mississippi River fit in the Atlantic Ocean

Given that,

Volume of the Atlantic Ocean = 3.1*10^17cubicmetres

Annual flow of the Mississippi River = 6.3*10^11cubicmeters

Now, we have to find how many times the annual flow of the Mississippi River fit in the Atlantic Ocean

So,

= Volume of the Atlantic Ocean / Annual flow of the Mississippi River

= 3.1*10^17 / 6.3*10^11

= 0.4921*10^6 (Approximately)

=4.92*10^5

Therefore,

It takes 4.92*10^5 times for the Mississippi River to fit into the Atlantic Ocean.

The "machine" is subtracting 6 from whatever number she puts in. Ergo, 77 - 6 = 71.

Measurement is closest to the number of kilometers between these

two lighthouses is 219.2 kilometers.

Assume the distance between two lighthouses is x kilometers in 137 miles.

It knows there are approximately 8 kilometer in 5 miles.

The solved polynomial is 66x² -304x+94.

We are given a problem related to the polynomial function,  where Polynomial functions are expressions that will contain factors of changing degrees, coefficients, positive types, and constants.

Since the given  equation (11x-47)(6x-2),  both the term are in the form of multiplication, so here we use the distribute rule,

we  multiply the 6x-2 individually  with  the 11x and 47

11x(6x-2) -47(6x-2 )= 66x² -22x -282x + 94

Step-by-step explanation:

The slope intercept of the line is y = -1/3x -11

Slope-intercept is one of the special forms of line equation

The slope intercept of a line can be found by solving the slope-intercept equation of a line which is parallel to that line.

Slope-intercept equation is

y = mx + b

where m is the slope and b is the intercept.

The slope-intercept equation of the parallel line is

y = -1/3x + 4

The slope will be the same for both lines as they were parallel to each other.

Thus m = -1/3

The point in which the line passes is given as (-6,-9)

So with these data, We can find the intercept of the line

y = mx + b

where m = -1/3 and (x,y) is (-6,-9),Thus

-9 = -1/3(-6) +b

-9 = 6/3 +b

-9 = 2 + b

b = -9-2

b = -11

Thus the intercept of the line passing through the point (-6,-9) is -11

Thus, the slope-intercept equation of the line we need to find is

y = -1/3x -11

Answer: 161-80=81

(or 161-x=y?)

Step-by-step explanation:

subtract the the amount of snowballs made before Adrianna's dad called them in for lunch from the total number of snowballs (161-80)

161-80=81

He finished the number of books by the time he arrived = 3.3 books, b) she withdrew $15 from her bank account. c) 6 people have nothing on their feet.d) He must wait before he can buy the pair of shoes = 20 minutes. e) After dividing the bank gives him 700 nickels = $35. f) She spent more money on lunch than breakfast  = $3. g) After eating the mirage slices left = 6 slices. h) He has more green highlighter than blue  = 3

a) professor finished  3 books by the time he arrived.

   Professor x traveled to see jean grey = 1500 miles

   He read one book he traveled = 450 miles

    So,

   He finished books by the time he arrived by dividing both the numbers = 1500/450

      He finished total books by the time he arrived = 3.3 books

b) Storm had money = $74

She bought a pair of slacks = $34

She bought two shirts = $16

She bought a pair of shoes = $24

After shopping she left with = $15

Storm expenses on the items = $34 + $16 + $24

                                              = $74

So, after shopping she left with $15 so it is clear that she withdrew $15 from her bank account.

c) Pacific northwest geocachers in wolverine’s living room = 12

Wearing shoes = 4

Wearing socks = 6

Wearing both socks and shoes = 4

As we know 4people wearing both socks and shoes

So, 2 people are wearing only sock

And no people wearing only shoes = 4-4=0

So, in total 4+2+0= 6

Now, 12 people are there

So, 12-6=6

So, 6 people have nothing on their feet.

d) Cyclops waited 20 minutes

Cyclops will buy a new pair of shoes = 1200 seconds

Here, 60 minutes = 3600 seconds

Now, divide 1200 seconds by a minute (1 minute = 60 sec)

 He must wait before he can buy the pair of shoes = 1200/60

  He must wait before he can buy the pair of shoes = 20 minutes

e) Quicksilver collected nickels in a jar  = 700

First, we have to calculate  how many cents are there in 700 nickels by multiplying 700 * 5, and then dividing that result by 100 cents

=700 nickels x 5 cents

= 3,500 cents   ( 100 cents = $1)

= 3,500 cents / 100 cents

The bank gives him 700 nickels = $35

f) For breakfast, Mystique bought a bagel = $1.55

A glass of orange juice = $2.25

At lunch,

On sandwich, she spent = $6.25

On a carton of milk, she spent = $0.55

Total spent on breakfast = $1.55+$2.25

                                       = $3.80

Total spent on lunch = $6.25+$0.55

                                = $6.80

She spent more money on lunch than breakfast =  $6.80-$3.80

She spent more money on lunch than breakfast  = $3

g) Mirage had 3 pizzas

Each pizza had = 8 slices

So, After multiplying total number of slice we have of the pizza = 3*8

                                                                          = 24 slices

He ate 75% of the pizza slices                         = 75/100 * 24

                                                                          = ¾ * 24

After multiplying,  he ate pizza slice                =   3 * 6

                                                = 18 slices

So, after eating by the mirage slices left = 24-18

                                                               = 6 slices

h) He has 3 more green highlighters than blue highlighters.

 In the iceman desk drawer, the number of  yellow highlighters are = 19

 As given, there are 15 more blue highlighters than yellow in his desk drawer

 Then,

 the number of blue highlighters  = 19+15

                                                           = 34

There are total numbers of green highlighters = 37

He has more green highlighters than blue highlighters = 37-34

                                                                                      = 3
