Answer:
y = 2 x = -7
Step-by-step explanation:
2x+5y=-4 2x + 5y = -4 Add both equations
(-x-3y=1)2 -2x - 6y = 2
-y = -2
y = 2
Plug in 2 for y in the equations
-x - 3(2) = 1
-x -6 = 1
-x = 7
x = -7
Answer:
Step-by-step explanation:
Firstly convert each number into an improper fraction. 2 1/4 would become: 9/4 (because we multiply 2 and 4 and plus the numerator, to get the numerator and keep the denominator the same). Do this to all the numbers then multiply the numerator by the numerator and the denominator by the denominator. simplify normally and convert to a mixed number.

Step-by-step explanation:
I (did) the math for you
(look it up)
Answer: (x+(-4))^2 + (-67)
Step-by-step explanation:
To get -8, you must have (x-4)^2, and the expanded form of that is x^2-8x+16, so you need to subtract 67 to get 51.
