Answer:
4 = -5/2 * (-8) + b
4 = 20 + b
Subtract 20 from both sides:
= (16)4-20 = 20 + b -20
-16 = b
The equation would then be: <em>y = -5/2 x -16</em>
4.2530487 but you round it to $4.25
You get the answer by dividing 2.79 by 16.4 times 25
It's an isosceles triangle because they have two angles and two sides that are identical
Since the first angle should be 40 degrees more...

We Have in make 90 degrees with the rules, the complement angle must be 25
