What is the ordered pair of the solution -4x plus 8y equals 40 and -2x-2y equals 2?
[x = -4, y = 3]. There is more than 1 way to solve. Here's one:
- multiply second equation by 4: -8x - 8y = 8
- add to first equation {eliminating y}: -12x = 48
- divide this by -12: x = -4.
Now substitute x = -4 into either of the original equations:
- -2(-4) - 2y = 2
- 8 - 2y = 2 ---> -2y = -6 ---> y = 3.
Check in the other equation: -4(-4) + 8(3) = 16 + 24 = 40 [checks out]

What is the ordered pair to 2x-5y equals -1?
The equation 2x-5y=-1 has a graph that is a line. Every point on that line is an ordered pair that is a solution to the equation. So pick any real number x and plug it in. You will find a y and that pair (x,y) is an ordered pair that is a solution to this equation. For example, let x=0 Then we have -5y=-1so y=1/5 The ordered pair (0, 1/5) is a point on the line and a solution to the equation.

Is this ordered pair a solution to the inequality?
To determine if an ordered pair is a solution to an inequality, you need to substitute the values of the ordered pair into the inequality and check if the statement holds true. If the left side of the inequality evaluates to a value that satisfies the inequality when compared to the right side, then the ordered pair is a solution. If not, it is not a solution. Please provide the specific ordered pair and the inequality for a definitive answer.
