Answer:

$\boxed{\sf (f - g)(x) = x^2 + 10}$

Given:

f(x) = 2x² + 3

g(x) = x² - 7

To Find:

(f - g)(x)

Step-by-step explanation:

(f -g)(x) = f(x) - g(x)

= (2x² + 3) - (x² - 7)

= 2x² + 3 - x² + 7

= 2x² - x² + 3 + 7

= x² + 3 + 7

= x² + 10

A collection of nickels and quarters are worth $2.85. There are 3 more nickels than quarters. How many nickels and quarters are

Alex777 [14]

Answer:

nickels = 12

quarters = 9

Step-by-step explanation:

Let number of quarters be "q", and

number of nickels be "n"

Nickels are worth $0.05 and Quarters are worth $0.25

Since all of them are worth 2.85, we can write:

0.25q + 0.05n = 2.85

Also, we know, there are 3 more nickels than quarters, so we can write:

n = 3 + q

Now, we can substitute equation 2 into equation 1 to get:

$0.25q + 0.05n = 2.85\\0.25q + 0.05(3+q) = 2.85\\0.25q+0.15+0.05q=2.85$

Now, we solve for q:

$0.25q+0.15+0.05q=2.85\\0.3q=2.70\\q=9$

There are 9 quarters.

We know n = 3 + q

So,

n = 3 + 9

n = 12

There are 12 nickels
