Step-by-step explanation:
Answer:
-2 - 16 = -18
Step-by-step explanation:
-y+4c
You take the values for c and y and substitute them in the original equation.
It would then look like:
-(2) + 4(-4)
Solving that would be -2 -16 = -18
Sq root of 64 =8 so sq root of 65 must be just a little larger than 8
<span>Therefore answer is between 8 & 9

2x-3y=4
x+4y=-9/*(-2)
2x-3y=4
-2x-8y=18
-11y=22/:(-11)
y=-2
x+4*(-2)=-9
x-8=-9
x=-1
I hope this helped.
