Answer:
f(-3) = 21
Step-by-step explanation:
We "evaluate" the function f(x)=2x^2+3 at x = -3 by subbing -3 for x in f(x)=2x^2+3:
f(-3) = 2(-3)^2 + 3 = 2(9) + 3 = 21.
Thus, f(-3) = 21
Answer:
The lines would be equal, meaning the slope of the red line is also -3.
Step-by-step explanation:
SIMPLE:
Parallel lines have the same slope.
Answer:
The answer to your question is:
Step-by-step explanation:
Given
25² = 625
Show that
5⁻⁴ = 
Process
Find the prime factors of 25
25 5
5 5
1
Then 25 = 5²
Substitution
(5²)² = 625
(5)⁴ = 625
Get the inverse
(5⁴) ⁻¹ = 625⁻¹
But negative powers are not allowed, then,
9 < x
this means that x is a larger number than 9
9 = x
this means that x is equal to 9
