The correct answer is A.
Exponents should be multiplied when the expression is in the form (x^a)^b. In this case, the result is always equal to x^(a*b).
For B and D, the exponents should be added since the base is the same. Exponents in C should be subtracted since they are divided and cancel each other out

Step-by-step explanation:
I got this question right on a quiz. Hope this helps!!
G[(f(x)] = 2(-8x) + 3 = -16x + 3
- you replace the x in formula for g(x) by that for f(x) (ie -8x).
Answer:
C. 5 Red marbles
Step-by-step explanation:
If she started with 5 red marbles and had a probability of 1/5 of drawing a red marble, then there were 20 blue marbles, and 25 total marbles.
5/25 = 1/5
If she added 5 red marbles, she now would have 10 red marbles and still 20 blue marbles, giving her 30 total marbles in the bag.
10/30 = 1/3, so C is the right answer.
You can rule out other choices by repeating the above steps and substituting appropriate values
The line is wrong you would have to put a dot on -3 and then go up two and one over to the right and make a line
