Answer:
y = -8
Step-by-step explanation:
There is no x-variable as that would make the line tilt.
Hope this helps! Have a nice day!
Answer:
(x-13)(x+3) = f(x) = x^2 -10x -39
Step-by-step explanation:
Equation 1) 10x + 2y = 30
Equation 2) 4x + y = 4
Multiply all of equation 2 by 2.
2) 2(4x + y = 4)
2) 8x + 2y = 8
1) 10x + 2y = 30
Subtract equations from each other.
-2x = -22
Divide both sides by -2.
x = -22/-2
x = 11
B) x = 11
~Hope I helped!~
We have 
, to find inverse switch y and x then solve for y.
.
Hope this helps.
