Answer:
<em>-120m+60</em>
Step-by-step explanation:
You have to distribute the -15 into the numbers in the 8m-4.
So, <u>-15 times 8m</u> plus <u>-15 times -4</u>
-15 times 8m is <u>-120</u>
-15 times -4 is <u>60</u>
Therefore, the answer is -120m+60
48% of 50
Find 10%= 5 ( move the decimal place once)
5x4=20
To find the 8% find 1% which equals 0.5 ( move the decimal point 2 places) then 0.5x 8= 4
Add 40% =20 and 8%=4
=24

Answer:
a(n) = 1/2(-8)^(n-1)
Step-by-step explanation:
The general term of a geometric sequence is ...
a(n) = a(1)×r^(n-1)
where a(1) is the first term, and r is the common ratio.
Here, the first term is a(1) = 1/2. The common ratio is the ratio of any two sequential terms: r = 32/-4 = -8. Then the explicit formula is ...
a(n) = 1/2(-8)^(n-1)
