Answer:
B. 5^2
Step-by-step explanation:
When an exponent has an exponent, they are multiplied. The negative exponents go to the denominator. 5^14/5^-12 Since the terms are divided the exponents are subtracted. 5^2
Answer:
The inverse function is f(x) = (x - 1)/2
Step-by-step explanation:
To find the inverse of any function, start by switching the x and f(x) values.
f(x) = 2x + 1
x = 2f(x) + 1
Now solve for the new f(x). The result will be your inverse function.
x = 2f(x) + 1
x - 1 = 2f(x)
(x - 1)/2 = f(x)
5x + 4 + 2x + 5
First add the like terms.
You will get this: 7x + 9
And these can't be simplified anymore because they do not both go into the same multiple.
So your answer will be:
7x + 9
Answer:
16-4x^2
Step-by-step explanation:
u start multiplying them by each other .
4×4= 16
4×2x= 8x
-2x×4= -8x
-2x×2x= -4x^2
now u combine like terms
8x+-8x = 0
16-4x^2
I hope u understood.... lol
Answer:
9
Step-by-step explanation:
√x+5-2=0
√x+3=0
√x= -3
x=9 [(-3)*(-3) = 9]
