Answer:
5y+3x=-9
Step-by-step explanation:
Let us start by the general form of the standard equation, Ax+By=C. One way we can solve this problem is by finding the <u>slope-intercept form</u> of this equation, y=mx+b, and converting it into the standard equation. In the slope-intercept form, m represents the slope, b represents the y intercept.
From this problem, we are given both the slope and the y intercept. We know have the equation:
Great! Now let us rearrange the terms so that the y and x terms are on one side of the equation.
This seems right, but a standard equation must have coefficient values that are real numbers. So, A and B must be real numbers. We can do this by multiplying the entire equation by 5 and ridding the denominator of the A term.

Answer:
A. Drink 1
B. Drink 2
Step-by-step explanation:
We are given that,
The quantities of fruit juice in original recipe are:
Apple juice = =
Orange juice = =
= 3
Pineapple juice =
So, we get that,
The proportion of apple juice to pineapple juice in the original recipe is =
.
Now, according to the options , we will check which drink have apple to pineapple juice ratio equal to .
Simplifying the mixed fraction into rational numbers, we get,
Drink A: =
.
Drink B: =
.
Drink C: = 5
Drink D: =
= 4
Drink E: =
.
So, we see that,
Drinks A and B have the same proportion of apple to pineapple juice as that of the original recipe.
