Answer:
Step-by-step explanation:
Slope intercept form is , so we have to find a way to substitute the given information into the equation. We have because it gives us the slope. The slope is -1, as the directions state. Now, we substitute it in and solve for b:
- Substitute -1 in for m⇒
- Substitute in the point (-1, -4) in for and respectively to get
- Solve the equation to get b= -5
After getting the y-intercept, you have the full equation!
For vertex form, half the middle term and square it
(x2 + 4x + 16) + 18 - 16
so...
(x + 4) ^2 + 2
One operator is missing. I will assume it is a + and that the equation is: 4y -2/5y +4/5 = -3
Solution step by step
1) Sum -4/5 to both sides
4y - 2/5y + 4/5 - 4/5 = -3 -4/5
2) Sum alike terms
18/5 y = -19/5
3) Multiply both sides by 5
18 y = -19
4) Divide both sides by 18
y = -19/18
The answer to this question would be: 5 1/2 pints
A quart is a unit that used for volume. A quart would be equal to 2 pints or 1/4 of gallons. A quart is also roughly equal to 4 cups. In this question, you asked to convert quarts into pints. Then the calculation would be:
Quart = 2 pints
2 3/4 quart = 2 * (2 3/4 pints)= 4 6/4 pints = 5 2/4 pints= 5 1/2 pints
