Step-by-step explanation:
5 gallons 3 quarts +4 gallons 2 quarts
5.3
+
4.2
=9.5 gallons
So first you distribute the 5 to the x and the +2 and get
5x+10=3(x+8)
then you distribute the 3 to the other x and the +8 and get
5x+10=3x+24
subtract 3x from both sides
2x+10=24
subtract 10 from both sides and get
2x=14
divide both sides by 2 and get
x=7
Yes, it is an equivalent expression because even though you move two pieces of an equation it will still equal the same thing, unless there are parentheses involved.
Midpoint coordinates are ( - 2 + 2) / 2 , (-1+3) / 2
= (0,1) Answer
Y=2x+6
gradient is found from the formula,

y intercept is found by subbing the values of (-1,4) into the equation y=2x+c
