The equation in slope intercept form is y= 1x - 70
Answer:
<h2>a = 400/21, b = 580/21</h2>
Step-by-step explanation:
Small triangles are similar. Therefore, the sides are proportional
<em>cross multiply</em>
<em>divide both sides by 21</em>

For b, we can use the Pythagorean theorem:

A. 2x + 1 (2x is the "twice a number")
b. x - 6 (x is the number being decreased)
c. 2/3x
