Answer:
x=0 x=9
Step-by-step explanation:
f(x) = x^3 - 9x^2
Set equal to zero to find the zeros
0= x^3 - 9x^2
Factor out x^2
0=x^2 (x-9)
Using the zero product property
0=x^2 0=x-9
x=0 x=9
100 = 10^2
so 10^9 * 10^2 = 10^11 kilometers in 100 years
Answer:
464 $
Step-by-step explanation:
Answer:
18x
Step-by-step explanation:
Since all 3 are monomial terms with the same variable, we can add them together:
5x + 3x = 8x + 10x = 18x
z = -11
Steps:
8z+12 = 5z-21
Subtract 12 from both sides
8z+12-12 = 5z-21-12
Simplify
8z = 5z-33
Subtract 5z from both sides
8z-5z = 5z-33-5z
Simplify
3z = -33
Divide both sides by 3
3z/3 = -33/3
Simplify
z = -11
