The ordered pair (2,2) satisfies which of the following equations?:
Select one:
a. 2x+2y=11
b. 2x+2y=4
c. 2x−4y=−4
d. 2x+y=5
Nevermind, I just figured out what to do.
yes 4 - 8
To determine which equation the ordered pair (2,2) satisfies, we need to substitute the values of x and y into each equation and see which equation holds true.
Let's start with option a:
2x + 2y = 11
Substituting x = 2 and y = 2:
2(2) + 2(2) = 11
4 + 4 = 11
8 ≠ 11
The equation does not hold true for option a.
Moving on to option b:
2x + 2y = 4
Substituting x = 2 and y = 2:
2(2) + 2(2) = 4
4 + 4 = 4
8 ≠ 4
The equation does not hold true for option b.
Next is option c:
2x - 4y = -4
Substituting x = 2 and y = 2:
2(2) - 4(2) = -4
4 - 8 = -4
-4 = -4
The equation holds true for option c.
Finally, let's check option d:
2x + y = 5
Substituting x = 2 and y = 2:
2(2) + (2) = 5
4 + 2 = 5
6 ≠ 5
The equation does not hold true for option d.
Therefore, the ordered pair (2,2) satisfies the equation 2x - 4y = -4, which is option c.
