Answer:
A
Step-by-step explanation:
x | y
0 0
1 4
2 n -> 8
3 12
I've rewritten the x-y table so it's easier to read.
Take a point: 2,8. 2 times 4 is 8.
Take another point: 3,12. 3 times 4 is 12.
Ooh, looks like we have a pattern! After testing all the points (which you should always do in case there's an outlier) each x is multiplied by 4 to get the y. The formula for this is <u>y=kx,</u> where k is the constant of proportionality. So the equation is <u>y=4x.</u> This means x and y are directly proportional.
(They would be inversely proportional if in the form y=k/x; jointly proportional if they were in the form z=kxy, and nonproportional if there was no relationship at all.)
Answer:
300,000
Step-by-step explanation:
you have 290 for the first three numbers the 9 is above 5 making the numbere infront of it go up so it would be 300,000
1-5 stays the same and 6-9 go up.

Title of the video Rounding to the Nearest Hundred Thousand / My Growing Brain
The length of the floor increased by 30% would be 33x1.30 = 42.9 feet.
The scale is 1 cm = 6 feet.
The drawing would be:
42.9 / 6 = 7.15 cm long
The answer is C.
The amplitude here would be 5
