(B) x = 40
Step-by-step explanation:
4x + 20 = 180
4x = 160
x = 40
Answer:
1) solve x+1/x = 5
2) solve x³+1/x³
substitute x = 1/4 into the expression
No because (0,1) isn't a solution for both equations. It is for the first one, but not the second.

Answer:
-8
Step-by-step explanation:
you need to rewrite it in y=mx+b form where b-is the y-intercept
y-4= -3(x+4)
distribute
y-4 = -3x-12
isolate y
y= -3x-8
compare this with the y=mx+b so y-intercept is -8
