Simplify what's in brackets first, then move to what's in the parenthesis
3(x+4)=9
3x+12=9
3x=-3
x=-1
Hope this helps :D
(2,-5),(-1,4)
slope = (4 - (-5) / (-1 - 2) = (4 + 5) / -3 = -9/3 = -3 <==
To find the unit rate, divide total miles by number of gallons:
418 miles / 16 gallons = 26.125 miles per gallon
Round the answer as needed.
