Answer: 
Step-by-step explanation:
<h3>
The missing question is: "What is the Functions formula A(t)=?"</h3><h2 />
The equation of the line in Slope-Intercept form is:

Where "m" is the slope and "b" is the y-intercept.
According to the data given in the exercise, you know that:
-
represents the area to paint the Hiros' romm as a function of time.
- The rate he painted the room was 8 square meters per hour.
- The area left to paint after 3 hours was 28 m².
Therefore, based on this, you can idenfity that:
1. The slope of the line is:

2. One of the point on the line is:
So you must substitute the slope and the coordinates of that point into
and then solve for "b" in order to find its value:

Therefore, you can determine that the function
is:

Answer:
The correct answer should be C.
The 4th option.
The values with no x or y attached are the y intercept
6x - 7y = 21
Subtract 6x from both sides
6x - 7y - 6x = 21 - 6x
-7y = 21 - 6x
Divide both sides by - 7
-7y/-7 = 21/-7 - 6x/-7
Y = -3 +6x/7
The why intercept, -3 is the same as the one in the question
Answer:
Formula: width x depth x height
Step-by-step explanation:
times 100 and 3. As we know that the formula for a box is width x depth x height.
We need to measure the box from all side so 4 sides. so times the 2 number by 2 cause there is 4 sides each.
Hope this helps
