If y varies directly as x, and y is 20 when x is 4, what is the constant of variation for this relation?

Ludmilka [50]

Answer:

Step-by-step explanation:

y = k*x This is the formula for a direct variation.

y = 20
x = 4 Substitute these values into the direct variation

20 = 4 * k Divide by 4

20/4 = 4k/4

k = 5

Answer: the constant of variation is 5

Answer:

1) (4,4) 2) (4,0) 3) (6,1)

Step-by-step explanation:

$(\frac{5+13}{2} )(\frac{7+1}{2} )\\(\frac{8}{2} )(\frac{8}{2} )\\(4,4)$

$(\frac{-3+7}{2} )(\frac{-3+3}{2} )\\(\frac{4}{2} )(\frac{0}{2} )\\(4,0)$

$\frac{-5+x_2}{2} =1$ multiply 1 by 2=2 then write $(+5)-5+x_2=1(+5)\\x_2 = 6$

$\frac{3+y_2}{2} =2$ multiply 2 by 2= 4 then write $(-3)3+y_2=4(-3)\\y_2=1$
