Answer:
y = -2x - 2
Step-by-step explanation:
Slope-Intercept Form: y = mx + b
Points: (3, 4)
Slope: -2
y = -2x + b
4 = -2 ( 3 ) + b
4 = -6 + b
b = -2
y = -2x - 2
Well... Basically, you should prove this by SSS property(side-side-side). It's fair to say that the length of a side is equal to itself so The line that cuts through the rectangle is a side for both rectangles. Thus because of the given, all the sides of the triangles are equal to one another. This is a very important trick for geometry(I remember using it a lot).
Hope this helps!
There would be $13410 because 4500 x 0.22 x 9 = 8910
4500 + 8910 = 13410
