F(x) = 3x^2+6x-2
= 3(x^2+2x-2/3)
= 3(x^2 +2x + 1 - 1 - 2/3)
= 3((x+1)^2 - 1 - 2/3)
= 3((x+1)^2 -5/3))
= 3(x+1)^2 - 5
So our function is in the form:
f(x) = 3(x+1)^2 - 5
where a = 3, h = -1, k = -5
14x + 11y = 896
x = number of adults
y= number of kids
if nine adults went then 70 kids went

Answer:
Step-by-step explanation:
We have been given that in a recent year, 304 of the approximately 300,000,000 people in the United States were struck by lightning.
Therefore, the probability that a randomly selected person in the United States will be struck by lightning this year is .
U plug in the y
2 (3x) -5x=4
simplify
6x -5x =4
solve
x=4
so now you know x=4 so plug that in for x
y= 3(4)
y=12
check your answer
2(12)-5(4)=4
solve
24-20=4
4=4
so you now you got the answer right !
hope that helps!
