There are 2 terms with x so you add them
Answer: 9x+5y
The vertex of the function is at x = -3/2. We cannot find the y value with an incomplete equation.
To find the x value of a vertex, we use the equation -b/2a, in which a is equal to the coefficient of x^2 (in this case 1) and b is equal to the coefficient of x (in this case 3).
-b/2a
-3/2(1)
-3/2
This gives us that value. To find the y value, you would plug this into the equation. Since this equation is not complete, you cannot do that yet.
Answer:
look below
Step-by-step explanation:
x - 5 = 7
x = 12
.................
x - 8 = 20
x = 28
.................
x + 2 = -1
x = -3
................
x - 9 = 12
x = 21
...............
x + -6 = -7
x = -1
.................
x - 8 = -3
x = 5
..................
-7 - x = -9
-7 = x - 9
2 = x
