Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7

Answer: I think it's 583...
Step-by-step explanation:
Hypotenuse or C (x) can be found with the equation

After solving you get about 6.32
6.32 about the same as
B- -3
If x is two according to the coordinate points, that means the equation is now -8+3y=-17
Add 8 to each side- 3y=-9
And divide -9 by 3
This gets you y=-3
