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)
<u>Answer:</u>
- The solution of the inequality is x < -2.
<u>Step-by-step explanation:</u>
<u>Let's simplify the inequality first.</u>
- => -4x < 8
- => -4x/4 < 8/4
- => -x < 2
- => x < -2
Hence, <u>the solution of the inequality is</u><u> x < -2.</u>
Hoped this helped.

Answer:
Parallel
Step-by-step explanation:
QR and ST both parallel to y axis.
<span>y = 5x - 9 a straight line
If y = 0 then 5x-9 = 0 0r x = 9/5
If x = 0, then y = -9
The straight line can be drawn from (9/5,0) to (0,-9) and extended to infinity both ways.
