Answer:

n = 30

Step-by-step explanation:

since it cost 90 to keep open, the equation needs to equal 90

90 = ?

because it cost 13 for a book and x equals the amount of books

90 = -13x

because you make 16 for each book

90 = -13x + 16x

now you can simply

90 = 3x

x = 30

so the answer is 30

Tamiku [17]

Julie travelled with 30.5 miler per gallon.

<u>SOLUTION: </u>

Given, On Julie's trip to the mountains she traveled 192 miles using 6 gallons of gas.  

On the return trip she traveled 235 miles on 8 gallons of gas.  

We have to find how many miles per gallon did Julie get on the way there?

We know that,

\text { number of miles per gallon }=\frac{\text { total distance travelled }}{\text { total number of gallons }}

Substituting the values we get,

=\frac{192+235}{8+6}=\frac{427}{14}=30.5 \text { miles per gallon }

Hence, Julie travelled with 30.5 miler per gallon on the way there on mountains.

Which equation represents the graph?
frosja888 [35]

Answer:

The answer is A) y+4 =3(x+3)

Step-by-step explanation:

The slope is the rate of change, which you can see from the graph is m = 3/1 = 3.

Your options are given in point-slope form:

y-y1=m(x-x1)

Pick a point from the graph. I used;

(-3, -4). Now plug this into your point slope form equation.

y-(-4) = 3(x-(-3))

y+4=3(x+3)
