2y^2+ 2(9y^2 -8)
= 2y^2+ 18y^2 -16 (distributive property)
= 20y^2 -16
The final answer is 20y^2 -16~
Step-by-step explanation:
First, find the vertex. The x coordinate is -b/2a, or 12/-4=-3. Plug this back in to get -18+36-21 or -3, so the vertex is (-3, -3). Now, slowly make the x -2, -1, 0, 1, on and on. Because parabolas are symmetric along the vertex, they will have the same values as -4, -5, -6, on and on.
Answer:
with what?
Step-by-step explanation:
2y+4=3(y-1)
2y+4=3y-3
4+3=3y-2y
Y=7
X=2
Answer:
It is a function.
Step-by-step explanation:
Functions are relations in which one domain value is assigned to exactly one range value. The x-value must not repeat in the relation set for it to be a function.
{(2,3), (4,3), (6,3), (5,9), (3,9)}
There are no repeating x-values given.
The relation should be a function.
Hope this helps.
