The equation has a slope of 4
The graph has a slope of 1
The equation has a greater rate of growth.
Would it help if you wrote it as
?
Then you can cross multiply if you know how to do that.
1*x = (-11)(-3)
x = 33 but what happened to the 2 minus signs?
Remember that a ( - ) times a ( - ) = a plus. The two minus signs become a plus.
Positive.
I'm assuming its like:
What's - / -.
If that's the case the quotient would be positive.
The two horizontal lines are parallel, so the smaller triangle is similar to the entire triangle.
That means the sides are proportional to each other. So pick two sides of the triangle and find the ratio between them. The ratio must be the same for both triangles.
(15/5) = (15+x)/8
Solve for x.
15*8 = 5(15+x)
120 = 75 + 5x
5x = 45
x = 9
