Answer:
See the graph attached. It has one solution: (6,-4)
Step-by-step explanation:
The slope-intercept form of a line is:

Where m is the slope and b is the intersection of the line with the y-axis.
Given the first equation 
You can identify that:
b=-1
Substitute y=0 to find the intersection with the x-axis

This line passes through the points (0,-1) and (-2,0)
Given the second equation:

Solve for y:

It passes through the point (0,-4).
Now, you can graph. See the figure attached.
It has one solution,which is the point of intersection of both lines: (6,-4)
Answer:
The Answer is: The factors reduce to 60x.
Step-by-step explanation:
First the parenthesis, then the bracket, then the multiplication:
5x[(26 - 4) - (4 + 6)]
5x[22 - 10]
5x[12]
60x

Answer:
3
Step-by-step explanation:
If this isn't a trick question then the answer is 3.
Let width = x then
2x+ 2(x + 2) = 80
4x + 4 = 80
4x = 76
x = 19
so the width is 19 and the length is 21 answer
