Answer:
k = 10
Step-by-step explanation:
X progresses by 25, while y progresses by 250.
So divide 250 ÷ 15 and your answer is 10.
Since all the option shows the variation is direct..
I. E y=kx let's take the first one to find the k and as well the relationship
When y=24,x=20
24=k*20
K=24/20
k=6/5
K=1.2....
30 of the divisors are multiples of 3
The factors of 2160 are 1, 2160, 2, 1080, 3, 720, 4, 540, 5, 432, 6, 360, 8, 270, 9, 240, 10, 216, 12, 180, 15, 154, 16, 135, 18, 120, 20, 108, 24, 90, 27, 80, 30, 72, 36, 60, 40, 54, 45, 48
These are all divisors of 2160 but only 30 are multiples of 3.
The ones that are NOT are 1, 2, 4, 5, 8, 10, 16, 20, 40 and 80
You can also do this using prime factors 2x2x2x2x3x3x3x5 = 2160 but it is harder to explain.
What Do you need help with if you added a picture we cant see it
right 3 units down 5 units
right 3 units = (3,0)
down 5 units = (0,-5)
vertex = (h,k) therefore.
Then convert the vertex form into standard form for the equation in the choice.
Thus, the answer is B.
