Answer: 
or (1,1)
Step-by-step explanation:
You can apply the Method of substitution.
Knowing that 
(second equation), you can substitute it into the first equation and solve for the variable y:
Now you need to substitute 
into the second equation to calculate the value of the variable x. Then:
Then, the solution is:
or (1,1)
Answer: OPTION C.
Step-by-step explanation:
The systems of linear equations can have:
1. <u>No solution:</u> When the lines have the same slope but different y-intercept. This means that the lines are parallel and never intersect, therefore, the system of equations has no solution.
2. <u>One solution</u>: When the lines have different slopes and intersect at one point in the plane. The point of intersection will be the solution of the system
3. I<u>nfinitely many solutions</u>: When the lines have the same slope and the y-intercepts are equal. This means that the equations represents the same line and there are infinite number of solution.
Therefore, based on the explained above, the conclusion is: Systems of equations with different slopes and different y-intercepts <em><u>never</u></em> have more than one solution.

Answer:
the answer is nonagon
A nonagon is a polygon made up of 9 sides and 9 angles.
Step-by-step explanation:
you know the area of a rectangle is length × width.
we know length = 10 m.
and we know the area = 60 m².
60 = 10×width
width = 60/10 = 6 m.
the fence is the perimeter, which is for a rectangle
2×length + 2×width
which is logical, as when you fully go around a rectangle, you have to pass the length 2 times and the width 2 times, right ?
length of fence = 2×10 + 2×6 = 20 + 12 = 32 m.
