property of integer exponent states that to multiply two powers with the same base, add the exponents .
aˣaⁿ = a⁽ˣ⁺ⁿ⁾
So last option is the correct choice.
Okay so the mean is 3, standard deviation is 2.16 and the variance is 4.66.

Answer:
1st Graph
Step-by-step explanation:
Step 1: Find the inverse
y = 2x - 2
x = 2y - 2
x + 2 = 2y
y = (x + 2)/2
Step 2: Graph the inverse
Simply use a graphing calculator and we should see our answer is the top left graph.
Answer:
5x+3x=8x
