It would have to be letter B because the exponents add up to the lines in the graph so in conculsion it is letter B.
<em>Product hints at multiplication so -5n is AT LEAST meaning that it is at or greater than 35....</em>

-5n ≥ 35
Answer:
9, 10, 2 and 1/5, 42, 8, 12
Step-by-step explanation:
Answer:
28:35
Explanation:
Given the reason for step 5, Corresponding sides of similar triangles are in proportion, we are looking for sides that will be corresponding to 2x+28 and 95. 2x+28 is the length of QP and 95 is the length of PR. The matching option in our list is 28:95, because 28 is the length of SP and 35 is the length of PT.
Answer: The car is 6.6 years old.
Step-by-step explanation:
Hi, to answer this question we have to replace the values in the equation given:
Y = 1/2 (half the value)
A = 1 (total value)
r =10% = 0.10 (decimal form)
Replacing:
y = A(1-r)^t
1/2 = 1 (1-0.10)^t
Solving for t:
(1/2)/1 = 0.9^t
1/2 = 0.9^t
log 1/2 = log 0.9^t
log 1/2 = (t) log 0.9
(log 1/2)/ log 0.9 = t
6.57 =t
6.6 years (rounded)
