Answer: Option A. The solution set is (4,5)
Step-by-step explanation:
Solve the equation for<em> </em>y to obtain the form of the equation of the line.
You have:
y=-x+9 (The slope is -1 and the y-intercept is 9)
y=x+1 (The slope is 1 and the y-intercept is 1)
When you graph it you obtain the graph shown in the figure attached.
The solution is the intersection of the lines.
Then, the solution set is (4,5)

Step-by-step explanation:
-102-
98 so the answer is -86
Domain: {x>= -9} x belongs to real numbers
graph is attached
It will take both of them 2 11/12 hours to complete the room
<h3>Fractions and proportions</h3>
Fractions are written as a ratio of two integers. For instance a/b is a fraction.
Let the time it will take them to complete the job together be "x" such that;
1/x = 1/5 + 1/7
Simplify
1/x = 7+5/35
1/x = 12/35
Cross multiply
12x = 35
x = 35/12
x = 2 11/12 hours
Therefore it will take both of them 2 11/12 hours to complete the room
