Aguest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent. this can be represented by the equation y = 30(0.92)d, where y is the number of phone calls after d days. how many phone calls should she expect after a week?
a. 28
b. 23
c. 17
d. 2

C. 17

Step-by-step explanation:

Given: A guest on a talk show tends to receive many phone calls right after she is on the show, and then the calls become less frequent.

This can be represented by the equation , where y is the number of phone calls after d days.

Now, the number of days in a week = 7 days

Then, the number of phone calls she should expect after a week is given by :-

Hence, the number of phone calls she should expect after a week is 17.

option 3 . (5x + 1) - (-10x + 6)

step-by-step explanation:

option 1 :

(4x + 3) + (-9x + 4)

or 4x+3 -9x + 4

or -5x + 7

option 2

(x - 2) - (6x - 9)

or x-2-6x + 9

or -5x + 7

option 3

(5x+ + 6)

or 5x + 1 + 10x -6

or 15x -5

option 4

-4x+2x+7-3x

-7x + 2x + 7

-5x + 7

hence only option 3 did   not satisfy the given simplify expression.

is there a question here?
