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: 3:27
you would divide both by 3
3/3 =1
27/3= 9
so your ratio in simplest form is 1 cup of sugar: 9 cups of milk
Answer:
w = .5
Step-by-step explanation:
-4w + 18w+2=10 -6w
14w + 2 -2 = 10 -2 -6w
14w + 2w = 8 - 2w + 2w
16w = 8
16w/16 = 8/16
w = .5
Answer:
22
Step-by-step explanation:
Answer:
Step-by-step explanation:
1.
Equation one:
x = -5, x = -1 (Both are real)
Equation two:
No real solutions
Equation three:
x = -3 (Real)
Equation four:
No real solutions
2.
The easiest way to figure out if an equation has real solutions is to factor it. If it is factorable, then it has real solutions. If it isn't, then it doesn't have real solutions.
