A direct variation function contains the points (2, 14) and (4, 28). Which equation represents the function?

lara [203]

Answer:

$y=7x$

Step-by-step explanation:

we know that

A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form $y/x=k$ or $y=kx$

we have the points (2,14) and (4,28)

Find out the constant of proportionality k

$k=y/x$

For (2,14) ----> $k=14/2=7$

For (4,28) ----> $k=28/4=7$

the value of $k=7$

therefore

The equation is

$y=7x$

If G is the midpoint of FH find FG<br>fg=11x-7 gh= 3x+9

gavmur [86]

Solution:

we are given that

If G is the midpoint of FH, it mean that

$FG=GH$

we are also given that

$FG=11x-7 ,GH= 3x+9$

So we can write

$11x-7=3x+9\\
\\
11x-3x=7+9\\
\\
8x=16\\
\\
x=2$

So $FG=11x-7=11*\frac{1}{2}-7=11*2-7=15$
