I hope this helps
Step-by-step explanation:
carbonhydrates protein water fats minerals and vitamins
Subtract 85 from both sides to get 12x>165
Divide both sides by 12 to get 165/12
<span>X+(X+1)=31
</span>x is the first number and the second number should be x+1, since they are consecutive
To find both f(8) and f(-5), we will need to plug in their values for x and solve for each. Then, we can subtract them to find the final answer.
Finding f(8):
f(8) = 3(8) - 2
f(8) = 24 - 2
f(8) = 22
Finding f(-5):
f(-5) = 3(-5) - 2
f(-5) = -15 - 2
f(-5) = -17
Subtracting f(8) and f(-5):
f(8) - f(-5)
22 - - 17
22 + 17
39
