Answer: A:3 rolls B: $38.67
Step-by-step explanation:
1. Convert all units to the same value (feet to inches, as the opposite gives fractions)
2. Use new equation and multiply the said new variable (84*3 & 96*3)
3. The new total should amount to the total area (540)
4. Divide found area by 12 to convert back into feet (45)
5. Divide the feet by feet per roll (3)
6. Multiply for Cost
<u>ANSWER: </u>
If two points on line l above have coordinates (0, A) and (2, −3), then the value of A is -1
<u>SOLUTION:</u>
Given, two points on line l have coordinates (0, A) and (2, −3),
And the slope of the line is A,
We need to find a value.
We know that, slope of a line on which (x1, y1) and (x2, y2) are two points is given by

Here,in our problem,

now, substitute the values in formula we get

2A = -3 –A
2A+ A = -3
3A = -3
A = -1
Hence, the value of A is -1.
