Answer:
it isn't the equation so it can't be any roots...
Step-by-step explanation:
Start by converting your two equations into slope-intercept form.
3x - 3y = -9
-3y = -3x -9 Subtract 3x from both sides
y = x +3 Divide both sides by -3
2x + y = 9
y = -2x + 9 Subtract 2x from both sides.
Then graph both lines (in which case the point where they intersect is the solution) or substitute in each point until both equations are true.
In this case the solution is (2,5); both equations become 5=5 when you substitute in the point's coordinates.
The custodian will be able to repaint 4 6/7 bookcases with 1 4/7 gallons of paint because you have to divide the fractions 1 4/7 and 1/3. 1 4/7 divided by 1/3. You’d turn 1 4/7 into a mixed fraction, change the division sign to a multiplication sign, and flip 1/3. Now the equation is 11/7 • 3/1. Multiply 11 and 3 which equals 33 then multiply 7 and 1 which equals 7. The fraction you get should be 33/7 and then you simplify it and it becomes 4 6/7 which is the answer.
