Answer:
B
Step-by-step explanation:
p(x) = r(x) * s(x)
= (x + 5) *(-7) {Use distributive property}
= x * -7 + 5 * -7
= - 7x - 35

Step-by-step explanation:

First, we are going to find the common ratio of our geometric sequence using the formula:
. For our sequence, we can infer that
and
. So lets replace those values in our formula:
Now that we have the common ratio, lets find the explicit formula of our sequence. To do that we are going to use the formula:
. We know that
; we also know for our previous calculation that
. So lets replace those values in our formula:
Finally, to find the 9th therm in our sequence, we just need to replace
with 9 in our explicit formula:
We can conclude that the 9th term in our geometric sequence is <span>

Answer:
90/x=70/100 that's my answer
Lets say the initial cost is 100 dollars. The agent would buy it for 70 dollars. If he sold it for 10% more than what he bought it for, he would be selling it for 77 dollars, making a total profit of 37 dollars. This would mean that he made a 48% profit.
