D: neither
If you plug in x and y’s and multiply them neither of them will equal -5

good luck bro I believe in u
Answer:
2 months
Step-by-step explanation:
you can set up equations for each sister:
(Sarah) y = 3x + 30
(Anna) y = -2x + 40
you can graph them to find where they intersect (2,36) or:
you can set them equal to each other like the following:
3x + 30 = -2x + 40
5x = 10
x = 2
We want to write a linear equation for the recipe that describes the amount of oil that we need in terms of the vinegar.
The linear equation is: L = 3*V
So we know that the recipe calls for 1/3 tbsp of vinegar for every tbsp of oil.
Defining:
- V = amount of vinegar used
- L = amount of oil used.
The original equation is written as:
V = (1/3)*L
Now we want to rewrite this for L, this means, isolating L.
To do that we just multiply both sides by 3, so we get:
V*3 = (1/3)*3*L
V*3 = L
L = 3*V
This equation says that we will use 3 times more oil than vinegar.
