Answer:

Step-by-step explanation:

Let the renter drives 'x' miles

Company A:

Rental cost = 30 + 0.15x

Company B:

Rental cost = 20 + 0.20x

Given rental cost are same

20 + 0.20x = 30 + 0.15x

Subtract 20 from both sides

20 + 0.20x - 20 = 30 + 0.15x - 20

0.20x = 10 + 0.15x

Subtract 0.15x from both sides

0.20x - 0.15x = 10 + 0.15x - 0.15x

0.05x = 10

Divide both sides by 0.05

0.05x/0.05=10/0.05

x = 1000/5

x = 200

a) The renter has to drive 200 miles

b) Rental cost charged by company A = 30 +0.15*200

= 30 + 30

= $ 60

Rental cost charged by company B = 20 + 0.20**200

= 20 + 40

= $ 60

G(b) = 5b- 9 h(b) = (b - 1)^2 Evaluate. (hog)(-6) =

laiz [17]

Given:

The two functions are:

$g(b)=5b-9$

$h(b)=(b-1)^2$

To find:

The value of $(h\circ g)(-6)$ .

Solution:

We have,

$g(b)=5b-9$

$h(b)=(b-1)^2$

We know that,

$(h\circ g)(b)=h(g(b))$

$(h\circ g)(b)=h(5b-9)$

$(h\circ g)(b)=[(5b-9)-1]^2$

$(h\circ g)(b)=[5b-10]^2$

Putting $b=-6$ , we get

$(h\circ g)(-6)=[5(-6)-10]^2$

$(h\circ g)(-6)=[-39-10]^2$

$(h\circ g)(-6)=[-49]^2$

$(h\circ g)(-6)=2401$

Therefore, the value of $(h\circ g)(-6)$ is 2401.

Witch of these has a slope of -3/4 and a y intercept of 3/2

Arada [10]

Answer:

See explanation. (Also you can write an equation several different ways so without the choices I cannot tell you which)

Step-by-step explanation:

Slope-intercept form is y=mx+b

So one way to write the equation is y=-3/4 x +3/2

There are more ways to write it.

Every line about to write is a way to write it.

Multiply both sides by 4: 4y=-3x+6

Add 3x on both sides: 3x+4y=6

Subtract 6 on both sides: 3x+4y-6=0

There are a lot of ways to write an equation like this.

To better assist you I would need to see options.

Santino bought a book for $23.54. The price of the book was $22. What was the sales-tax rate?

IRINA_888 [86]

The sales tax rate would be 7%

23.54 - 22 = 1.54

1.54 / 22 = .07

.07 = 7%
