You find the x coordinates using x = -b/2a = -6/2(-1) = 3
Substitute 3 in the equation and find y
y = -(3^2) + 6(3) - 12 = -9 + 18 - 12 = -3
Vertex (3,-3)
Answer:
Y= -4 :)
Steps:
Apply rule
-y + 3 = 7
Subtract 3 from both sides
-y + 3 - 3 = 7 - 3
Simplify
-y = 4
Divide both sides by -1
-y/-1 = 4/-1
Simplify
y = -4
The equation for a line that passes through the point of (3, 9) and has a slope of 2 in slope intercept form is y=2x+3
3, 6, 9, 12, 15, 18, 21, 24, 27, 30.
By order of operation
5+1x10
5+10
15
By normal solving
