Let f(x)= 7x² + 4x and g(x) = -9x -- 2. What function represents a new function, h(x), for which h(x)=(f+g)(x)
a. h(x)= -2x² + 2x
b. h(x) = 7x2 + 5x - 2
c. h(r)= -2x² + 4x - 2
d. h(x) = 7x- 5x - 2

Answers

Answer 1

Answer:

Option D

Step-by-step explanation:

h(x) = (f+g)(x) = f(x) + g(x)

= 7x² + 4x +(-9x-2)

= 7x² -5x -2

Nicolas is setting up water stations for a 10-mile run. He already has the first one set up 8 miles from the starting line. He needs to set up two more that are 1.5 miles on either side of the first water station. Where will he put the two additional water stations?

A number line divided into increments of 1 and labeled 0 through 10. The number 8 is labeled with Nicolas.

The absolute value equation that models this situation is |x –
|=

.

The two additional water stations will be
and

miles from the starting line.

Answers

Answer:

Step-by-step explanation:

The two additional water stations will be 6.5 miles  and 9.5  miles away from the starting line.

Given Nicolas is setting up 3 water stations for a 10-mile run.

He already has the first one set up 8 miles from the starting line. He wants to set up two more that are 1.5 miles on both side of the first water station.

We have to calculate the distance of 2 other water station from starting point.

Now A number line divided into increments of 1 and labeled 0 through 10. The number 8 is labeled with Nicolas.

The absolute value equation that models this situation is |x –8 |=1.5

The two additional water stations will be (8-1.5) miles or 6.5 miles and other will be (8+1.5) or 9.5 miles away from the starting line.

The two additional water stations will be 6.5 miles  and 9.5  miles away from the starting line.

Answers

Answer:

60°

Step-by-step explanation:

Complementary angles sum 90°

a + b = 90°      Eq. 1

b = a/2             Eq. 2

Replacing Eq. 2 in the Eq. 1

a + a/2 = 90

2a/2 + a/2 = 90

3a/2 = 90

a = 90*2/3

a = 60

from the Eq. 2

b = 60/2

b = 30

Check:

from the Eq. 1

60 + 30 = 90

Susan buys a new computer 1200 dollars.Sales tax is 11%. How much does Susan actually have to pay?

Answers

Start by finding 11% of 1,200. To do so, multiply .11 by 1,200 to get 132. Add 132 to 1,200 to get 1,332.

In short, Susan has to pay *$1,332*

The amount that Susan actually have to pay should be considered as the $1,332.

Calculation of the amount:

Since the purchase price of the computer is $1,200

And, the sales tax rate is 11%

So here the total amount be like

= $1,200 + 11% of $1,200

= $1,200 + $132

= $1,332

hence, The amount that Susan actually have to pay should be considered as the $1,332.

Jenny is making tie dyed shirts for her class with her school colors, blue and yellow she used a total of 8 ounces of fabric paint the amount of blue paint is 3 times the amount of yellow make a diagram to show the ratio of blue to yellow paint

Answers

Answer:

The ratio of blue paint to yellow paint is 3:1

Step-by-step explanation:

Let

x -----> the amount of blue paint in ounces

y ----> the amount of yellow paint in ounces

we know that

x+y=8 -----> equation A

x=3y -----> equation B

Solve the system by substitution

Substitute equation B in equation A

3y + y = 8

4y = 8

y = 2

Find the value of x

x = 3(2) = 6

therefore

The amount of blue paint is 6 ounces and the amount of yellow paint is 2 ounces

Find the ratio

To find out the ratio of blue paint to yellow paint, divide the amount of blue paint by the amount of yellow paint

x/y = 6/2 = 3/1

That means -----> Of every 4 parts of paint, three parts are blue and one part is yellow.
