Answer:
=
9
Step-by-step explanation:
x^2 =144 has 2 solutions
x=sqrt(144)
x=+-12
x= 12 and x=-12
12*12 = 144 and (-12) * (-12) = 144
a square root has 1 positive and 1 negative solution
x^3 = 27
(x^3)^(1/3)=(27)^(1/3) ^(1/3) is the cube root
x = 3
it only has one solution because a negative * a negative * a negative would be negative
Answer:
y = x + 2
Step-by-step explanation:
