Which situations can be presented by an exponential function?
select each correct answer
a. in a structure made of soup cans, each row has 6 more cans that the previous row
b. a doctor’s office accepts 20 new patients each month
c. the value of a motorcycle decrease by 12% each year
d. every year, the number of online subscribers to a service is 4 times what it was the previous year

It’s C and D I just finished the text and finished with 100% thanks to the person in the comments in the question below

Step-by-step explanation:

c and d

Step-by-step explanation:

i just took the test

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

the answer is (-8,-5)

step-by-step explanation:

the endpoint to midpoint is half the length. the length is (-2,-1) so when you are at the midpoint just add it to it to find your answer -6+(-2)= -8 and -4+(-1)=-5 so (-8,-5)
