2x+3y= -17
5x+2y= -4
You must cancel either the x or y out to solve so i'm going to cancel the x.
-5(2x+3y= -17)
2(5x+2y= -4)
This simplifies to:
-15x -15y=85
15x+4y= -8
The -15x and 15x cancel out leaving you:
-15y=85
4y= -8
You add them top numbers by the bottom and get:
-11y=77
Then divide by -11 to get y by its self.
y= -7
Now that you know what y is just plug it in to either original problem. I will use the second one.
5x + 2(-7) = -4
5x -14 = -4
5x = 10
x = 2
So the answer is (2,-7) or x=2 and y=-7
Answer:
5.01 x 10^-2
Step-by-step explanation:
Move the decimal two times to the right so it becomes 5.01 and since you moved the decimal to the right the exponent will be negative.

Answer:
half the diagonal is given as 7 yards, the full diagonal would be 7 x 2 = 14 yards.
The formula for the length of a side of a square using just the diagonal is:
Side = √2(d/2)
Side = √2 (14/2)
Side = √2(7)
Side = 9.9 yards.
The area of a square is S^2
Area = 9.9^2
Area = 98.01
Area = 98.0 Yards^2
