<h3>Answer:  x^2 + 6</h3>

Work Shown:

(f o g)(x) = f(g(x))

f(x) = x + 7

f( g(x) ) = g(x) + 7 ... replace every x with g(x)

f( g(x) ) = x^2-1 + 7 .... plug in g(x) = x^2-1

f( g(x) ) = x^2 + 6

(f o g)(x) = x^2 + 6

A van travels 260 miles on 13 gallons of gas. Find how many gallons the van needs to travel 500 miles?
FinnZ [79.3K]

Answer:

  25 gallons

Step-by-step explanation:

Assuming miles-per-gallon is a constant, the amount of gas is proportional to the miles driven:

  gallons/(500 mi) = (13 gal)/(260 mi)

  gallons = (500 mi)/(260 mi)(13 gal) . . . . multiply by 500 mi

  gallons = 25 gal . . . . do the arithmetic

The van will need 25 gallons of gas to go 500 miles.

Hello can u please help
Andrei [34K]

y = mx + b

-3 = -2(-5) + b

-3 = 10 + b

-13 = b

y = -2m - 13

The line would pass through -13 on the y-axis and it would go down 2 and move to the right 1 for every new point.

Hope this helps! ;)
