Answer:
{x,y} = {67/16,-15/4}
Step-by-step explanation:
// Solve equation [2] for the variable y
[2] 2y = -8x + 26
[2] y = -4x + 13
// Plug this in for variable y in equation [1]
[1] 4x + 5•(-4x+13) = -2
[1] -16x = -67
// Solve equation [1] for the variable x
[1] 16x = 67
[1] x = 67/16
// By now we know this much :
x = 67/16
y = -4x+13
// Use the x value to solve for y
y = -4(67/16)+13 = -15/4

Answer:16
Step-by-step explanation:8 times 2
You have to multiply the 6 by both s and -9
So you will get 6s - 54 which is the answer
<h3><u>The correct answer is A and B.</u></h3>
Both A and B represent functions, as the same x value is not used twice.
However, with option C, the x value -2 is used twice, and thus it is not a function.
