The graph above shows the costs of two phone plans. How many minutes does a person need to call each month so that Plan B is the less expensive plan to use?

A. Less than 10 minutes

B. More than 10 minutes but less than 20 minutes

C. More than 30 minutes but less than 40

D. More than 40 minutes

Answer: for b: function one has a greater rate of change

Step-by-step explanation: sorry i don't know the first one

Answer:

a) -2 and 4, b) function 2

Step-by-step explanation:

Rate of change is the same thing as slope. For the first function, the table, we can use two of the points and the slope formula. I'll use (-1,3) and (-2,5). Remember the slope formula:

[tex]m=\frac{y2-y1}{x2-x1}[/tex]

Plug the points in:

[tex]m=\frac{5-3}{-2-(-1)}\\m=\frac{2}{-1}\\m=-2[/tex]

(Remember that subtracting a negative = adding. I look at it like the two 'minus' signs form one plus sign, if that helps)

So the slope of function 1 is -2.

We can do the same thing with the second function. Two points that I notice on the graph are (-1,0) and (0,4). Let's use the same slope formula.

[tex]m=\frac{4-0}{0-(-1)}\\m=\frac{4}{1}\\m=4[/tex]

And the slope of function 2 is 4. That answers the first part. The second part asks about rate of change.

Function 2 has a greater rate of change, since 4>-2.

Hope this helps!

Answer:

"Team C scored 130 points."

Step-by-step explanation:

Let x represent how many points team B scored.

Team A: 3x + 6

Team B: x

Team C: x + 45

Total: 476 points

476 = (x) + (3x + 6) + (x + 45)

476 = x + 3x + 6 + x + 45

476 = 5x + 51

425 = 5x

x = 85

Team A:

3(85) + 6

= 261 pts

Team B:

= 85 pts

Team C:

(85) + 45

= 130 points

m = 7.25

Step-by-step explanation:

8m + 7 - 5 = 60

Evaluate like terms.

8m + 2 = 60

Isolate 8m.

8m = 60 - 2

Evaluate.

8m = 58

Find m.

m = 58 ÷ 8

m = 7.25

Answer:

Step-by-step explanation:

l8m+7l = 65

(8m+7) = 65     or    -(8m+7) = 65

8m = 65-7   or      -8m = 65 + 7

m= 58/8    or       m = 72/(-8)

m= 7. 25 or      m = -9

71 cookies were sold at $2.00 each, whereas 35 cookies were sold at $3.00

What are simultaneous equations?

Simultaneous equations are related equations that are solved together to determine their unknown variables

Given : bags of cookies sold for $2.00, $2.50, or $3.00, depending on the size. altogether, 106 cookies were sold, and $256 was earned for the sales.

Let X be number of cookies sold at $3.00

Then  cookies sold at $2.00 would be 2X

2X+X=106

3X=106

X=106/3

X=35(cookies sold at $3.00)

cookies sold at $2.00=106-35

cookies sold at $2.00=71

Inverse: If G is not at 4, the GH is not 3

Contrapositive: If GH is not 3, then G is not 4

2: Converse: If QR =(~) RS, then R is the midpoint of QS

Inverse: If QR does not =(~) RS, then R is not the midpoint of QS

Contrapositive: If R is not the midpoint of QS, the QR does not =(~) RS.

Step-by-step explanation:

Converse is to switch the two

Inverse is to make them both untrue, like if 1 +1 is 2, then 2+2 is 4, you could say if 1+1 is not 2, the 2+2 is not 4

Contrapositive is to switch them around and make them both untrue

Based on the calculations using the given x-intercept of this graph, the value of a is equal to 11.

A linear function can be defined as a type of function whose equation is graphically represented by a straight line on the cartesian coordinate.

In Mathematics, the y-intercept of any graph (parabola) occurs at the point where the value of "x" is equal to zero (0). Similarly, the x-intercept refers to the point at which the graph of a function crosses the x-axis and the value of "y" is equal to zero (0).

Given that the x-intercept is at (a, 0), we would simply substitute the given points as follows:

y = (x − 4)^2 − 49

0 = (a − 4)^2 − 49

(a − 4)^2 = 49

Taking the square of both sides, we have:

a - 4 = √49

a - 4 = 7

a = 7 + 4

a = 11.

Given the total number of notes is eight and their value total is $550, then you have 5 notes of $50 and 3 notes of $100

As per the question statement, You have [tex]x[/tex] number of $50 notes and [tex]y[/tex] number of $100 notes. Their total value of $550 and total number of notes are eight. We are supposed to calculate the value of [tex]x[/tex] & [tex]y[/tex]

This question is a classic example of how to form and solve linear equations. For solving this, we will have two equations, both in two variable x and y.

As we have total 8 notes, therefore,

[tex]x+y=8[/tex]

And their total value is 550, therefore,

[tex]x*50+y*100=550[/tex]

From 1st equation we get, [tex]y=8-x[/tex]

substituting this in another equation, we get

[tex]x*50+(8-x)(100)=550\\50x+800-100x=550\\800-50x=550\\50x=250\\x=5[/tex]

Solving for y, we get

[tex]y=8-x\\x=5\\y=8-5\\y=3[/tex]

Therefore we have 5 notes of $50 i.e., [tex]x=5[/tex] and 3 notes of $100 i.e., [tex]y=3[/tex]

A location that is halfway between two other points is considered to be a line segment's midway. The distance between the midway and each endpoint is the same.

Given that the coordinates of the midpoint of a segment with the given points. 16,5 and 28,-13.

The midpoint will be calculated as:-

M = ( x₁ + x₂ ) / 2 , ( y₁ + y₂ ) / 2 ,

M = ( 16  + 28 ) / 2 , ( 5 - 13  ) / 2 ,

Answer:

k = 10

Step-by-step explanation:

For f(x) = x³ + kx² - kx - 93 to be divisible by (x+3) with no remainder, it means that at (x + 3) is a factor of the polynomial f(x).

Thus, it means that at x = -3, f(x) must be equal to zero.

Thus;

(-3)³ + k(-3)² - k(-3) - 93 = 0

-27 + 9k + 3k - 93 = 0

12k - 120 = 0

12k = 120

k = 120/12

k = 10

Answer: ) (0,0), (0,2), (2,0), (4,2); Maximum value of 10

Answer:

balloons= 9

candles= 8

Step-by-step explanation:

let the number of balloons be x

and candles be y

So

15x+8y=192----------1

x+y=17--------------2

from 2, x= 17-y

put x= 17-y in 1

15( 17-y)+8y=192

255-15y+8y=192

solve for y

-7y=192-255

-7y=-63

x=63/7

x=9

put x= 9 in 1

9+y=17

y= 17-9

y=8.

Answer:

26/9

Step-by-step explanation:

whenever you divide fractions, they turn into a multiplication problem and use the second fraction's reciprocal. so it would look something like this:

13/2 * 4/9

just do straight multiplication

numerators: 13*4 = 52

denominators: 2*9 = 18

52/18 = 26/9
