-7n + 9 because the common difference is -7, so you have -7n, and then by plugging in the term numbers and the values, you find out that you need to add 9 to the -7n, so the answer is -7n + 9

We need 6.5% to a decimal so..
6.5% /100 = 0.065

$21.30 X 0.065 = 1.3845 tax on the shirt
 
So.. we add the price of the shirt, and the amount of tax on the shirt
$21.30 + 1.3845 = $22.6845

Answer = $22.68

If B is the midpoint of AC, AB = 8x + 5, and BC = 5x2 - 16, then find x and AC
Murljashka [212]

Answer:

Step-by-step explanation:

AB = 8x + 5

BC = 5x² - 16

5x² -  16 = 8x + 5

5x² - 8x - 21 = 0

Quadratic formula

x = [8 ± √(8² – 4·5(-21))] / [2·5]

 = [8 ± √484] / 10

 = [8 ± 22] /10

 = -1.4, 3

-1.4 is an extraneous solution.

x = 3

AB = 8x+5 = 29

AC = 58

You're using inverse operation to solve this equation. Now you just have to think about it. What number plus 20 would equal the same number squared? The answer would be 5, since
5+20=5^2
25=25
 The statement above is true :)
Another number that would work for the equation would be x= -4
-4+20=-4^2
16=16
The statement above is also true so your answer would be x=-4 and 5
