Let f(x) = 5x - x+1 and g(x) = -3x. Evaluate the composition (f • g)(1).

Replace the variable x with 1 in the expression

f(1)=5(1)−(1)+1

f(1) = 5

Replace the variable x with 1 in the expression.

g(1)=−3⋅1

g(1) = -3

Multiply 5 by −3

.

−15⋅1

Multiply −15

by 1

.

−15

Thus, the answer is -15

I am unsure about this answer, I have doublechecked it several times.  Please take this with a grain of salt

54 km / hours

step-by-step explanation:

we need to convert seconds to hours

60 seconds = 1 minutes

60 minutes = 1hour

15 m         60 second   60 minutes

  * *         = 54000 meters/ hour

second     1 minute             1 hour

now we need to convert meters to km

1000 m = 1 km

54000 m       1 km

*   = 54 km / hours

hour               1000m

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2
