If f(x) = 8 - 10x and g(x) = 5x + 4, what is the value of ()?
-196
-168
22
78

()=-168

step-by-step explanation:

() means f(-2) times g(-2).

so if we can find the value of each of the functions at x=-2, all we have to do at the end is multiply our results to find ().

let's begin.

f(-2):

f(x)=8-10x for x=-2

f(-2)=8-10(-2)

f(-2)=8+20

f(-2)=28

g(-2):

g(x)=5x+4 for x=-2

g(-2)=5(-2)+4

g(-2)=-10+4

g(-2)=-6

so now finally f(-2) times g(-2) gives you:

28(-6)

-168

answer: given that the roller coaster can accommodate 1600 riders per hour, thus the roller coaster can accomodate 1600 / 60 = 26.67 riders per minute.

given that there are 345 people in the line, the number of minutes it will take for the 345 persons to get into the roller coaster is given by 345 / 26.67 = 12.94 minutes.

therefore, it will take you 12.94 minutes to get to the front of the line.

step-by-step explanation:

the answer is: the length is 5/6 yards.

give me a or a 5 star rating if this is correct!
