Answer:
B
Step-by-step explanation:
(x,y) = P + (a)t
(x,y) = (4,7) + t(3,8)
(x,y) - (4,7) = t(3,8)
(x-4, y-7) = t(3,8)
So this way we can do it. Thankyou!
Answer:
the amount of matter is mass. how much space you take up
Step-by-step explanation:
Direct variation in mathematics is when two numbers are written in an equation where one of the numbers multiplied by a constant term to equal the other.
In the table in the equation, we see direct variation.
<u>X</u> <u>Y
</u><u></u>1 7
2 14
3 21
4 28
We can find the constant of the variation by dividing y by x. This constant should remain the same for all terms of x in the table with their corresponding y values.
y/x
7/1=7
14/2=7
21/3=7
28/4=7
As we can see, the values in the table all share a direct variation between x and y with the value 7.
This can be expressed in an equation: y = 7x.
