First you simplify both sides of the equation to make v+-41/9=-3/4.
Then add -41/9 to both sides to get the answer which is 137/36
v=137/36
-18 +15x = y

Step-by-step explanation:
take 3000 and minus that by 30 percent, then after that, add 7 percent to get your total.
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.
Equation B is written in vertex form, which means you can read the vertex (extreme value) from the numbers in the equation.
Vertex form is
y = a(x -h)² + k
where the vertex (extreme point) is (h, k). Whether that is a maximum or a minimum depends on the sign of "a". When "a" is negative, the graph is a parabola that opens downward, so the vertex is a maximum.
Equation
B reveals its extreme value without needing to be altered.
The extreme value of this equation is a
maximum at the point
(2, 5).
