Jane = x years

Tom = x+8

*5 Years Ago

Jane= x-5

Tom= (x+8)-5=>x+3---------------------------
x+3=3(x-5)<span>x+3=3x-15
3x-x=18
2x=18
x=9 
Jane = 9 years
Tome = 9+8 = 17 years</span>

(a 3 - 2a + 5) - (4a 3 - 5a 2 + a - 2)
rosijanka [135]
(a^3 - 2a + 5) - (4a^3 - 5a^2 + a - 2)
=a^3 - 2a + 5 - 4a^3 + 5a^2 - a + 2
= -3a^3 + 5a^2 - 3a + 7

A rental car agency rents cars for $32 per day. They also charge $0.15 per mile driven. If you are taking a 5-day trip and have
xz_007 [3.2K]
So the equation is 32x+0.15y = $250
You know that you’re going to a 5-day trip so you can change x to 5
32(5)+0.15y = $250
You multiply 32 by 5 = 160
$160+0.15y = $250
And to simplify the equation(to make it easier) you subtract 160 on both sides
0.15y = $90
Now you’re trying to find y, so divide 90 by 0.15 to find the maximum of miles you can drive.
y = 600 mi
The maximum amount of miles you can drive is 600

Graph:
I can’t show any pictures sorry
But this is how you do it
Make a number line
Graph 600 with a closed circle, like this: ●
Then make an line going to the left(because you can’t go any more than 600)

Hope this helps! :^)
