Answer:

B

Step-by-step explanation:

(f - g)(x) = f(x) - g(x), then

f(x) - g(x)

= 49 - x² - (7 - x) ← distribute by - 1

= 49 - x² - 7 + x ← collect like terms

= - x² + x + 42 → B

Answer:

x

Step-by-step explanation:

Answer:

a rational number

Step-by-step explanation:

The value of the expression is 1.12 x 10^6

The expression is given as

(14.1 x 10^5) - (2.9 x 10^5)

Factor out 10^5 from the above expression

So, we have:

(14.1) x 10^5 - (2.9) x 10^5

Factor out 10^5 from the above expression

So, we have:

(14.1- 2.9) x 10^5

Evaluate the difference

11.2 x 10^5

Rewrite as

1.12 x 10^6

Hence, the value of the expression is 1.12 x 10^6

Answer:

t < 3.8 minutes

Step-by-step explanation:

We are told that the temperature "t" minutes after being cooled is

60(5/6)^t

We want to find After how many

minutes will the temperature of the solution be less than 30°C

Thus;

60(5/6)^t < 30

Divide both sides by 60 to get;

(5/6)^t < 0.5

t In(5/6) < In 0.5

-0.1823t < -0.6931

t < 0.6931/0.1823

t < 3.8 minutes

Answer:

A. The y intercept the y coordinate when the line passes through the point that is on the y coordinate and the x is 0. In this context, the y intercept is 10.

B. The slope is the number of units the line goes up every number of units it goes to the right. This line goes up 50 every 20 units to the right so the slope is 50/20 which simplifies to 5/2

C. The equation is y = 5/2x + 10

Answer:

8(7+6)

Step-by-step explanation:

The given inequality holds for the open interval (2.97,3.03)

It is given that

f(x)=6x+7

cL=25

c=3

ε=0.18

We have,

|f(x)−L| = |6x+7−25|

          = |6x−18|

          = |6(x−3)|

          = 6|x−3|

Now,

6|x−3| <0.18  then |x−3|<0.03 ----->−0.03<x-3<0.03---->2.97<x<3.03

the given inequality holds for the open interval (2.97,3.03)

Answer: 19, 35

Step-by-step explanation:

Two numbers: x and y.

x+y=54

x+16=y

x+x+16=54

2x+16=54

2x=38

x=19

19+y=54

y=35

19, 35

Answer:

x = 35

y = 19

Step-by-step explanation:

16 + x + y = 54

-16              -16

x + y = 38

          ÷2

x = 19

y = 19

The larger number is 16 more than the smaller number

x = 19 + 16 = 35

x = 35

y = 19

35 + 19 = 54

54 = 54

Answer: 8% Error

Step-by-step explanation:

Lets go ahead and change the equation to a format that we're more familiar with.

Original:

50 -> 46

But what's easier is if we are working with 100's because of 100% right?

So lets do this.

100 -> 92

All I did was multiply both by 2 to get 100 to 92. Now it's easier to determine because of what we're looking at. 100-92 is 8% which also makes 50 to 46 an 8% error because of the symmetry between both equations. Enjoy!

Answer:

x=9

Step-by-step explanation:

10+5(x−4)=35 Step 1: Simplify both sides of the equation. 10+5(x−4)=35

10+(5)(x)+(5)(−4)=35(Distribute)

10+5x+−20=35

(5x)+(10+−20)=35(Combine Like Terms)

5x+−10=35

5x−10=35

Step 2: Add 10 to both sides.

5x−10+10=35+10

5x=45

Step 3: Divide both sides by 5.

5x/5 = 45/5

x=9

Answer:

x=13

Step-by-step explanation:

10+5(x-4)=35

10+5x+-20=35

5x+-30=35

5x=65

65 divided by 5=13

x=13

Answer: Store Z has the best sale price of $28.

Step-by-step explanation:

Here is the complete question:

Leo wants to buy some shoes. He found the shoes at three different stores for a price of $35. The stores are each having a sale.

Store X is offering 15% off the price of the shoes.

Store Y is offering $5 off the price of the shoes.

Store Z is offering a discount 1/5 off the price of the shoes.

Which statement about the sale price of these shoes is true?

a. Store X has the best sale price of $20.

b. Store Z has the best sale price of $28.

c. Store Y has the best sale price of $30.

d. Store Z has the best sale price of $7.

Since Store X is offering 15% off the price of the shoes, the price of the shoe at store X will be:

= $35 - (15% × $35)

= $35 - (0.15 × $35)

= $35 - $5.25

= $29.75

Since Store Y is offering $5 off the price of the shoes, the price of the shoe at store Y will be:

= $35 - $5

= $30

Since Store Z is offering a discount off the price of the shoes, the price of the shoe at store Z will be:

= $35 - (1/5 × $35)

= $35 - $7

= $28

Base on the analysis above, Store Z has the best sale price of $28.

Answer:

-14

Step-by-step explanation:

Find out how many times (-11) , (-1) and 17 appears.

(-11) is four times and (-1) is four time.

4 * (-1) + 4 * (-11) = 4 * (-1 - 11)

17 is appearing two times.

2*17

Now, the expression is,

4 * (-1 - 11) + 2 *17

4 * (-1 - 11) + 2 *17 = 4 *(-12) + 34

                            = - 48 + 34

                             = -14

Answer:

length of the rectangle is 19 cm and the width of the rectangle is 8 cm.

Step-by-step explanation:

The formula for the perimeter of a rectangle = 2L + 2 W

Where:

L = length and W = width

The rectangle shown has a perimeter of 54 cm

Its length is 3 more than twice its width.

2L + 2W = 54 .... Equation 1

"length is 3 more than twice its width."

L = 2W + 3.....Equation 2

Substituting 2W + 3 for L

We have:

2L + 2W = 54 .... Equation 1

2(2W + 3) + 2W = 54

4W + 6 + 2W = 54

6W = 54 - 6

6W = 48

W = 48/6

W = 8cm

L = 2W + 3.....Equation 2

L = 2(8) + 3

L = 16 + 3

L = 19 cm

Therefore:

length of the rectangle is 19 cm and the width of the rectangle is 8 cm.

Answer:

The area of the triangle is 16 feet because the are of the rectangle is 32 feet.

Step-by-step explanation:

The length of the rectangle is 8 feet. Since the dotted line is exactly in the middle of the rectangle, the bottom of the triangle s 4 feet. With 4 feet as the bottom and 4 as the height, we can calculate the area of one of the triangles ( 4 * 4 /2 ), so each of the triangle's area is 8 feet. Add them together, and you get 16!

Answer:

f(3) = - 2

Step-by-step explanation:

To evaluate f(3), substitute x = 3 into f(x) , that is

f(3) = 3 - 5 = - 2

Answer:

If [tex]f(x)=x-5[/tex], f(3) = -2

Step-by-step explanation:

We are given [tex]f(x)=x-5[/tex] and we need to find f(3)

For finding f(3), we put x= 3 in the given function.

[tex]f(x)=x-5[/tex]

Putting x=3

[tex]f(3)=3-5\\f(3)=-2[/tex]

So, if [tex]f(x)=x-5[/tex], f(3) = -2

Answer:

34 + 8n

Step-by-step explanation:

a₁ = 42

[tex]a_{n} = a_{n-1} + 8[/tex]

a₂ = a₁ + 8    = 42 + 8   = 50

a₃ = a₂ + 8   = 50 + 8 = 58

a₄ = a₃ + 8 =   58 + 8  = 66

Arithmetic sequence: 42, 50 , 58 , 66, ......

a₁ = 42 ; d = 8

[tex]a_{n}[/tex] = a₁ + d(n-1)

    = 42 + 8(n - 1)

    = 42 + 8n - 8

   = 34 + 8n

Answer:

[tex]a_{n}[/tex] = 8n + 34

Step-by-step explanation:

The explicit rule for an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Given the recursive rule

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 8

where + 8 is the common difference d , then

[tex]a_{n}[/tex] = 42 + 8(n - 1) = 42 + 8n - 8 = 8n + 34

Explicit rule is

[tex]a_{n}[/tex] = 8n + 34

Answer:

128 fluid ounces

Step-by-step explanation:

As per linear equation, there are 128 ounces of fluid in a gallon.

"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation.

The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, A is a coefficient and B is constant. The standard form of a linear equation in two variables is of the form Ax + By = C. Here, x and y are variables, A and B are coefficients and C is a constant."

Given relations for any fluid is:

1 cup = 8 ounces

1 pint = 2 cups

1 quart = 2pints

1 gallon = 4 quarts

Therefore,

1 gallon

=  4 quarts

= 4 (2) pints

= 8 pints

= 8(2) cups

= 16 cups

= 16(8) ounces

= 128 ounces

Therefore, for any particular fluid 128 ounces equal to 1 gallon.
