Answer:
Step-by-step explanation:
Given the equation
Divide both sides by 
Simplify
Add 9 to both sides
Simplifying
as
Therefore,
-3/4x + 5/6 y = 15
Multiply through by 6
-9/2x + 5y = 90
Add 9/2x to both sides
5y = 90 + 9/2x
Divide both sides by 5
y = 18 + 9/10x
y = 9/10x + 18
Comparing with the general equation of a straight line y = mx + c
Gradient (m) = 9/10 or 0.9
and the y - intercept (c) = 18
Answer:
i think 10 because in triangle there is 180 and 180-170 = 10
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.
