Question

Find the value of y for given value of x.

1.)x+5;x=3
2.)7x;x=-5
3.)y=1-2x;x=9
4.)y=3x+2;x=0.5
5.)y=2x^3;x=3
6.)y=x/2+9;x=-12

Answer 1

1.)x+5;x=3
(3) + 5
8


2.)7x;x=-5
7(-5)
35


3.)y=1-2x;x=9
y = 1 - 2(9)
y = 1 - 18
y = -17


4.)y=3x+2;x=0.5
y = 3(0.5) + 2
y = 1.5 + 2
y = 3.5


5.)y=2x^3;x=3
y = 2(3^3)
y = 2(3)(3)(3)
y = 2(27)
y = 54


6.)y=x/2+9;x=-12
y = (-12)/2 + 9
y = -6 + 9
y = -3
