How to solve the function problem for this one?

a. f(12) = - 1

b. x = 27 when f(x) = 4

Step-by-step explanation:

We are given that and we want to find f(12) and f(x) = 4

To find f(12) we simply plug in 12 into x and evaluate it

plug in 12

multiply 12 and 1/3 to get 4

subtract 5 from 4 to get -1

Now we want to find the value of x when f(x) = 4

To do this we substitute 4 for f(x) and solve for x

substitute 4 for f(x) and solve for x

add 5 to both sides

multiply both sides by 3

27 = x

And we are done.

So f(12) = -1 and x = 27 when f(x) = 4

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

part a

in a city ice cream is mostly only bought when the temperature is very high as ice cream cools down our

so we can derive the conclusion that as the temperature increases the number of ice creams sold also increases

part b

y intercept is 5

slope is 2
