If you would like to know what is the solution to the system of equations, you can calculate this using the following steps:<span>
2d + e = 8
d - e - 4 = 0 ... d = e + 4
___________________
</span>
<span>2d + e = 8
</span><span>2 * (e + 4) + e = 8
2e + 8 + e = 8
3e = 0
e = 0
d = e + 4 = 0 + 4 = 4
(d, e) = (4, 0)
The correct result would be: C. The solution is (4, 0).</span>
Answer:
the answer is 29x + 72, none of the following options does not have the answer
N=1.5 or -9/-6 start by distributing the -3 and then you want to seclude n by itself in order to solve for it
Answer:
25%
Step-by-step explanation:
The first doubling, from 20 to 40 occurs in a little more than 3 years, so the multiplier each year is a little less than 2^(1/3) ≈ 1.26. That is, each year is a little less than 26% more than the previous year.
The graph also goes near the point (8, 120), so grows by a factor of 6 in 8 years. That suggests a multiplier of 6^(1/8) ≈ 1.251. Each year is about 25.1% more than the previous year.
Both of these multipliers represent yearly growth rates near 25%.
___
Using the "rule of 72", the product of doubling time and percentage growth is about 72. So, for a doubling time of 3 years, the percentage growth is predicted to be near 72/3 = 24 percent.
All of these estimates help you choose the correct answer: 25%.
