Answer:
x=11
Step-by-step explanation:
Combine like terms:
3x +4 +6x =12- 41+ 6x
9x +4 =12 -41 + 6x
Subtract the numbers:
9x+ 4= 12- 41+ 6x
9x + 4= -29 +6x
Rearrange terms:
9x+4=-29+6x
9x+4=6x-29
x=11
Given: <span>y = x^2 + 6x - 5. Then a = 1, b = 6 and c = -5.
The x-coord. of the vertex is given by x = -b / (2a), which here is x = -6 / (2*1) = -3.
Use the given formula </span><span>y = x^2 + 6x - 5 to find the value of y when x = -3:
y = (-3)^2 + 6(-3) - 5 = 9 - 18 - 5 = -14
Then the vertex is (-3, -14).</span>
