Answer:
-4a+48
Step-by-step explanation:
Using the distributive property, you would multiply -4 with the values inside the brackets, which are a and -12.
-4*a + (-4*(-12))
= -4a+(48)
= -4a+48

Answer:
the answer of the question is 9.5
The given sum for n = 1 to n = 15 is equal to 255, so the correct option is B.
<h3>
How to find the sum of the given series?</h3>
We want to find the sum of the series whose elements are of the form:
(2n + 1)
From n = 1 to n = 15.
Then our sum will be:
(2*1 + 1) + (2*2 + 1) + ... + (2*15 + 1).
3 + 5 + ... + 31
This is the sum of all odd numbers in the interval [3, 31]
Which gives:

So the correct option is B.

Answer:
x y
2 76
4 64
7 47
9 34
13 10
Step-by-step explanation:
If we have an initial value of 88, that would be the y intercept
The rate of change -6 which is the slope
y = -6x+88
Let x =2
y = -6(2) +88 =
-12+88
= 76
Let y = 64
64 = -6x +88
Subtract 88 from each side
64-88 = -6x
-24= -6x
Divide by -6
-24/-6 =x x=4
Let y = 46
46 = -6x +88
Subtract 88 from each side
46-88 = -6x
-42= -6x
Divide by -6
-42/-6 =x x=7
Let x =9
y = -6(9) +88 =
-54+88
= 34
Let y = 10
10 = -6x +88
Subtract 88 from each side
10-88 = -6x
-78= -6x
Divide by -6
-78/-6 =x x=13
