f(x) = x^2 -3x +2

Replace x with 2:

f(2) = x^2 -3(2) +2

f(2) = 4-6 +2

f(2) = 0

g(x) = 4x-5

replace x with -1

g(-1) = 4(-1) -5

g(-1) = -4-5

g(-1) = -9

Now subtract

f(2) - g(-1) = 0 - (-9) = 0+9 = 9

The answer is 9.

Jackson rides his bike from his home for 30 minutes at a fast pace. He stops to rest for 20 minutes, and then continues riding i

Dimas [21]

Answer:

For the first 30 minutes, we will have a line with a given steepness, this will represent the 30 minutes riding at a fast pace.

Then he stops for 20 minutes, we will represent this with a constant line.

Then he again moves for another 30 minutes, but with a slower pace than in the first 30 minutes, then this line will be less steep than the first line.

A sketch of this situation can be seen below.

Oliver was counting his spare change. He had ten dimes and two quarter. How many times as many dimes does Oliver have than quart

zalisa [80]

1 quarter = 25 cents (he has 2 therefore its 50 cents)
10 dimes = 100 cents = 1 dollar
Oliver has twice as many dimes than he does quarters because 100 divided by 50 = 2. Hope this helps!
