Answer:
If x varies directly as y, then x=ky. y=5 and x=2.5 are substituted into x=ky to find k.
2.5=5k
k=2.5/5
k=5.
K =5 is substituted in x=ky to find y where x is 10.
x=5y
10=5y
y=10/2
y=2
y=mx+b
first find the y intercept or b or x=0
b=5
now find the slope
y²-y¹/x²-x¹--> 5-2/0-(-2)
m=3/2
the equation is D. y=3/2x+5
Answer:
3rd one
Step-by-step explanation:
2l + 2w = P
2w = P - 2l
w = P - 2l / 2
The relationship between the 7's is not different in any way because the sevens are all in the same place. The sevens are in the hundreds and thousands place.
1:2 means for every 1 drop of green there was 2 blue
6/2 = 3
