Answer:
n = -4
Step-by-step explanation:
6n + 9 = -3n - 21 - 6
combine like tmers:
6n + 9 = -3n - 27
add 3n to both sides:
9n + 9 = -27
subtract 9 from both sides:
9n = -36
divide by 9:
n = -4
The answer is A because there is a common difference of 3 and that makes it Arithmetric
A = 54 + 5t
A = 84 + 2t
54 + 5t = 84 + 2t
5t - 2t = 84 - 54
3t = 30
t = 30/3
t = 10....they will reach the same investment in 10 years
Answer:
Yes, (0,4) is a solution
Step-by-step explanation:
We have to plug in 0 in x and 4 in y IN BOTH THE INEQUALITIES.
IF BOTH ARE TRUE, then the system of inequalities is TRUE.
<u>Let's check:</u>
y ≤ -3x+4
4 ≤ -3(0)+4
4 ≤ 4
Is 4 less than OR equal to 4? Yes. THis is satisfied.
<u>Now, checking 2nd one:</u>
y > x^2 + 3x - 2
4 > (0)^2 + 3(0) - 2
4 > -2
Is 4 greater than -2? Yes, it is. So this is satisfied as well.
Hence, (0,4) is a solution to the system of inequalities shown.
