Kennan took his cousin to the carnival . For every 7 lollipops they won , they received 4 pieces of gum . if keenan counted 28 pieces of gum in their bag . how many lollipops did they have?

well the 1 and -1 are always after the 0 and the 0 is inthe middle. s thats what i would guess. but i dont know what a slope of 2 is sorry

step-by-step explanation:

answer: the first one

step-by-step explanation: use a calculator and divide the minutes by the dollars.

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation

you never say the total so we cant find the percentage used for petrol
