So 29-4 =25... which is a perfect square
Answer= +/- 5
Are you missing something?
2xy=7
5xy=9
does not have a solution.
If you mean
2x+y=7
5x+y=9
please say so.
Answer:
48, since the numbers are next to each other with no sign, they need to be multiplied, and a negative times a negative is a positive
Step-by-step explanation:
hope this helps
Y= -6 --> plug this -6 into the y of the 2nd equation
y= 4x+12 --> -6 = 4x+12 --> 4x = -18
x = -18/4 = -9/2 --> now this is the x solution coordinate, and we know that y must equal -6 from the 1st equation, so our solution point is:
(-9/2, -6)
Hope that helped!
