y = 3(x + 4)^2 + 31
Step-by-step explanation:
We can convert the given quadratic equation into its vertex form by completing the square:
y = 3x^2 + 24x + 43
= 3(x^2 + 8x) + 43
= 3(x^2 + 8x + 4) + 31
= 3(x + 4)^2 + 31
This is the vertex form of the given quadratic equation with (-4, 31) as its vertex
Answer:
The variable is z
Step-by-step explanation:
Answer:
Take the slopes, such that 7-4/-4+3= 3/-1=-3
So one endpoijt is (-5,10)
5.7t < 420 divide both sides by 5.7
5.7 5.7
t < 73.68
