Answer:
Alright so on this type of problem you just perform the operation they ask for, which in this case is subtraction.
Your first step will be to set up the problem:
f(x) - g(x)
Next you will substitute in your values:
(2x + 1) - (x2 - 7)
The easiest way to do the subtraction problems is to distribute your negative into your second set of parenthesis, so your expression would become:
2x + 1 - x2 + 7
Then combine your like terms:
2x - x2 + 8
Lastly put your expression in standard form (highest exponent to lowest)
-x2 + 2x + 8
Hope this helped!

Step-by-step explanation:
The price of one hat is $2 and price of one pair of mittens is $5.
Step-by-step explanation:
Let,
Price of one hat = x
Price of one pair of mittens = y
According to given statement;
5x+4y=30 Eqn 1
2x+3y=19 Eqn 2
Multiplying Eqn 1 by 2

Multiplying Eqn 2 by 5

Subtracting Eqn 3 from Eqn 4

Dividing both sides by 7

Putting y=5 in Eqn 1

Dividing both sides by 5

The price of one hat is $2 and price of one pair of mittens is $5.
