Which equation is y= 2x ^2 - 8x +9 rewritten in vertex form.
2 answers:
vertex form wow tht's advance um i'll say what you wrote up there is the answer
<span>y= 2x ^2 - 8x +9
</span>y = a(x - h)2<span> + k, where (h, k) is the </span>vertex<span> of the parabola
</span>so
y= 2x ^2 - 8x + 9
y= 2x ^2 - 8x + 8 + 1
y = 2(x^2 - 4x - 4) + 1
y = 2(x - 2)^2 + 1 ....<---------<span>vertex form</span>

Answer:
The two numbers are -4 and -5.
Step-by-step explanation:
Answer: 40 seconds. This is the equation graphed
102 times 4 =408
i know this because a square has 4 sides and i just need to multiply 102 and 4
q= -1/2
perpendicular slopes are those that are opposite sign and reciprocal of the original given slope
