Answer:
$1.93 per quart
Step-by-step explanation:
There are 4 quarts in a gallon and the jug of juice is 3 gallons.
4 * 3 = 12
Thus we have 12 quarts for a price of 23.16. If we divide the price by the quarts, we get price per quart.
23.16/12 = 1.93
Price per quart is $1.93
Do 9+4 because you need to get m alone. you get 13 plug 13 in for m (13-4=9) and then 9=9
This is the same as showing the following system of equations doesn't have a solution:
or in matrix form,
The quickest way to check if there is a solution is to check whether the coefficient matrix is invertible. If its determinant is 0, then it is not invertible.
And the quickest way to show that the determinant is 0 is by observing that the third row is a linear combination of the first two rows:
(-2, 9, 6) - (-3, 2, 1) = (-2 + 3, 9 - 2, 6 - 1) = (1, 7, 5)
So there are indeed no such scalars <em>c₁</em>, <em>c₂</em>, and <em>c₃</em>.
You are right, the third one is correct
Direct variation means that as x increases, y increases and as x decreases, y decreases
