question 1:

determine whether y varies directly with x. if so, find the constant of variation k and write the equation.

x y
2 4
6 12
10 20
14 28

a. yes; k=1 ; y=x
b. yes; k=2; y=2x
c. yes; k=3; y=3x
d. no

question 2:

determine whether y varies directly with x. if so, find the constant of variation k.

2x-4y=0

a. yes; k= 1/2
b. yes; k=2
c. yes; k=-4
d. no

the entire expression should be subtracted from 30. to subtract the quantity, distribute the negative sign, which changes the signs on the terms. so, the –2 changes to positive and gets added to 30 instead of subtracted from it.

hope this ! ^w^

function 2 has a greater rate of change than function 1

function 2 has a greater y-intercept than function 1

step-by-step explanation:

the formula for the equation of a circle is (x – h)2+ (y – k)2 = r2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. if a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
