Answer:
c.
Step-by-step explanation:
the most that can be factored out is -1.5,
-1.5 * w = -1.5w
-1.5 * -5 = 7.5
-1.5w + 7.5, so it's
-1.5(w-5)
Answer:
-6
Step-by-step explanation:
common ratio r=102/(-17)=-6
Continuous interest is Pe^(rt), but you are doubling your money in nine years so you want 2P=Pe^9t. Now divide both sides by P so 2=e^9t. Now take the ln of each side so ln2=9t. then just divide by 9. You will get a decimal, so move the decimal two places to the right to get your interest rate.
