Answer:
r(-2) = -5 , r(0) = -7 , r(5) = -12
Step-by-step explanation:
Plug in the numbers for x and then solve. : )
r(-2) = - (-2) - 7
r(-2) = 2 -7
r(-2) = -5
r(0)= -0 -7
r(0)=0-7
r(0) = -7
r(5) = -5 - 7
r(5) = -12
Answer:
x=1
Step-by-step explanation:
(15x^3- 2)^3= 2197
Take the cube root of each side
(15x^3- 2)^3 ^ 1/3= 2197^ 1/3
15x -2 = 13
Add 2 to each side
15x^3- 2+2= 13+2
15x^3 =15
Divide each side by 15
15x^3 /15 =15/15
x^3 =1
Take the cube root of each side
x^3 ^1/3 = 1^1/3
x=1
