Answer:
Step-by-step explanation:
You're given a coordinate in the form of (x, y) and you're also given the vertex in the form of (h, k). We will use those in the vertex form of the equation
and solve for a. Filling in:
which simplifies a bit to
and a bit more to
. Add 3 to both sides to get
-8 = 4a so
a = -2
The equation, then, is
Subtract the 12x^2 first.
5x - 4 = 6
Add the four
5x = 10
Then divide the 5 from both sides
X = 2
Answer:
(5x + 2) - (-9x - 2)
O 11x2 – 5x + 8
14x + 4
–6x2 + 8x 7
-X2 + 6
Step-by-step explanation:
Answer:
-1/4
Step-by-step explanation:
You multiply the numerators, 3 multiplied by -1=-3.
Then the denominators, 4 multiplied by 3=12.
This means the answer is -3/12, but then you can simplify it to -1/4.
15 boys and 16 girls....total is (15 + 16) = 31
probability that a boys name is drawn : boys/total ppl = 15/31
