Step-by-step explanation:
Given the information above, we can simply set up an equation so we can find the value of x.
Subtract 42 on both sides.
Divide 14 on both sides.
So, the value of x is equal to -1/2 when f(x) is 35.

Answer:
500 and 900
Step-by-step explanation:
3(x - 300) + 2(x + 100) = 3300 ← distribute parenthesis
3x - 900 + 2x + 200 = 3300
5x - 700 = 3300 ( add 700 to both sides )
5x = 4000 ( divide both sides by 5 )
x = 800
Then
cost of book = x - 300 = 800 - 300 = 500
cost of pen = x + 100 = 800 + 100 = 900
The line is horizontal, therefore the slope is 0.
Answer=0
