Vertex form is
y=a(x-h)²+k
vertex is (h,k)
to solve
input the given vertex and then the given point, solve for a
vertex at (-2,2) and a point is (-4,-10)
y=a(x-(-2))²+2
y=a(x+2)²+2
put point (-4,-10)
-10=a(-4+2)²+2
-10=a(-2)²+2
-10=4a+2
-12=4a
-3=a
y=-3(x+2)²+2
Answer: (2p + 1.5d) + (5*(2)) = T
Step-by-step explanation: (2p + 1.5d) + (5*(2)) = T
Since there are no costs, i'll make up my own uwu;
Matinee = $5
Popcorn = $2
Drink = $1.5
T = total
(2p + 1.5d) + (5*(2)) = T
2p ($2 for each bag of popcorn - p represents popcorn)
1.5d ($1.5 for each drink, - d represents drinks)
5*2 ( 5 * 2 because we are already given the amount of matinee tickets they buy.
Answer:
D: x < 20
Step-by-step explanation:
-4x + 16 > -64
subtract 16 from both sides because you must isolate x.
-4x + 16 - 16 > -64 - 16
-4x > -80
Then divide -4 on both sides... I believe that when you divide a number by a negative number you must flip the sign...
-4x/ -4 < -80/ -4
x < 20
(negative divided by a negative will result in a POSITIVE.)
Hope this helped... I truly apologize if this is wrong..
Answer:
62.22%
Step-by-step explanation:
First, find how many total marbles there are:
12 + 11 + 17 + 5
= 45
Then, find how many marbles that are not blue:
12 + 11 + 5
= 28
Then, divide 28 by 45, and multiply by 100
(28/45) x 100
= 62.22% is the probability of not choosing a blue marble
