Answer: D, .1
Step-by-step explanation: 10 marbles and 1 green
50 times she pulled and almost every ten tries she got green meaning there's a high chance of her getting 1 green every 10 tries
Answer:
-3a^3 + 2a.
Step-by-step explanation:
21a3 − 14a / -7
= 21a^3 / -7 - 14a / -7
= -3a^3 + 2a.

Answer:
-3 is the value of k in g(x)=kf(x)
Step-by-step explanation:
Both functions cross nicely at x=-3 so I'm going to plug in -3 for x:
g(x)=kf(x)
g(-3)=kf(-3)
To solve this for k we will need to find the values for both g(-3) and f(-3).
g(-3) means we want the y that corresponds to x=-3 on the curve/line of g.
g(-3)=-3
f(-3) means we want the y that corresponds to x=-3 on the curve/line of f.
f(-3)=1
So our equation becomes:
g(-3)=kf(-3)
-3=k(1)
-3=k
So k=-3.
