Answer:
Step-by-step explanation:
Given:
If there is a coefficient in front of a or , that means it becomes an exponent.
Simplify the exponent.
When there is addition between two logarithms or natural logarithms, it means they multiply together.
Answer:
640.5 cm^2
Step-by-step explanation:
So the formula for trapezoid is height times the average of the bases. So 25+36=61, and then we divide that by 2 to get 30.5 as our average. Then, we take 30.5 and multiply it by 21 and we get 640.5.
AB means A X B so you have to do 14 / 9 which is 1.5 or there abouts.
51.25 per month which is $615 per year
They save 5 per month if they pay full year
(51.25-5)= 46.25 per month is $555
so it costs $555 if they pay all at once.
Answer: C) y = -5x + 27 and D) y = 2x - 15
<u>Step-by-step explanation:</u>
Substitute x = 6 and y = -3 into each of the given equations to see which result in a TRUE statement.
A) y = -3x + 6
-3 = -3(6) + 6
-3 = -18 + 6
-3 = -12 FALSE
B) y = 2x - 9
-3 = 2(6) - 9
-3 = 12 - 9
-3 = 3 FALSE
C) y = -5x + 27
-3 = -5(6) + 27
-3 = -30 + 27
-3 = -3 TRUE!
D) y = 2x - 15
-3 = 2(6) - 15
-3 = 12 - 15
-3 = -3 TRUE!
E) y = -4x + 27
-3 = -4(6) + 27
-3 = -24 + 27
-3 = 3 FALSE
