Need help with 7 and 8

Question 7 answer = 31

Question 8 answer = 128

Step-by-step explanation:

If n represents the number in the sequence, then for Question 7, you would do 5(8) - 9. 5 times 8 = 40 - 9 = 31.

Then, for question 8, 6-1 = 5, and you raise 2 to the 5th power because it is the one in parentheses. 2^5 = 32. Then, you multiply 4 times 32 to get 128.

5x + 5

step-by-step explanation:

you should always add the diagrams and graphs we cannot see. this particular question is kind of borderline because we can make a graph for you.

(f + g)x = -x^2 +3x + 5 + x^2 + 2x

(f + g)x = 5x + 5

the graph of z = 5x + 5 is shown below. always use desmos when in doubt.

step by step solution :

step   1   :

1.1     4 = 22

(4)3 = (22)3 = 26

equation at the end of step   1   :

  ((23) • 26)2

step   2   :

equation at the end of step   2   :

  (23 • 26)2

step   3   :

final result :

  218
