<span>x2 + 9x = 0
x(x+9) = 0
x=0
x+9 = 0; x = -9
answer is </span><span>a 0, -9</span>
Given:
Nick has x toy race cars. This is one-third of what Bob has.
So, the number of Nick toys = one-third of what Bob has.
Let the Bob has y toys
So, we can write the following expression:

Solve for y, multiply both sides by (3):

So, the answer will be:
Bob has (3x) toy race cars.
-3/x is the answer I believe
I hope this helped:)
Answer:
a = 
Step-by-step explanation:
Given
ga + q = r ( subtract q from both sides )
ga = r - q ( isolate a by dividing both sides by g )
a = 
Look at the picture.
Mark the point (-1, 5) in the coordinate system.
We have a slope of m = 2 = 2/1.
Therefore, go 2 units to the right and 1 unit to up.
Mark the second point.
Draw a line passing through the given points.
