Which equation shows y=−1/2x+4 in standard form?
a. 2x+y=8
b. x+2y=8
c. x+2y=-8
d. 2x-y=8

B. x+2y=8

Explanation:

The original equation is:

The problem asks us to convert the equation in the standard form, so in the form

with a,b and c being integers.

In order to do that, first of all let's bring on the same side both x and y:

Now we want the coefficient in front of x to be an integer, so let's multiply each term by 2, and we get

and this corresponds to option B.

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).
