D is the answer
because you are doing y=2(x+3)^2 - 5
First, do exponents
(x+3)(x+3) = x^2 + 6x + 9
now Multiply your answer by 2
2(x^2 +6x + 9) = 2x^2 + 12x + 18
Then, Subtract 5 from 18
2x^2 +12x + 18-5 = 2x^2 + 12x + 13
bringing you to answer D
Answer:
x = -5
Step-by-step explanation:
The equation y = x^2+10x+25 can be factored to (x+5)^2
when (x+5)^2 = 0
x = -5
meaning the equation has a line of symmetry at x = -5
Answer:
a = -8
Step-by-step explanation:
you can solve this proportion by cross-multiplying:
4(a + 9) = -1(a + 4)
now distribute to eliminate parentheses
4a + 36 = -1a - 4
5a + 36 = -4
5a = -40
a = -8
I thought I already answered this but its -10
Well we know that he sold 20 glasses every hour. if h is the number of hours he worked we know the expression would be 20h
1 hr = 20 glasses
2 hr = 40 glasses
3 hr = 60 glasses
Keep the pattern going to figure out which hour he got his 100th glass sold.
