Answer:
-10x+10y-6
Step-by-step explanation:
-4x+17-2y-6x+12y-23
-10x+17-2y+12y-23
-10x+10y+17-23
-10x+10y+-6
If anything is in parentheses do that first, however if there isn’t you always do exponents next so evaluate 6 squared
Hope this helps!!

Answer:
Step-by-step explanation:
In any "solve for" scenario, you identify what operations are performed on the variable of interest, then undo them in reverse order.
Here, the square root of d is multiplied by a constant. To undo these operations, we first divide by the constant. That gives ...
Then, we square both sides of the equation to undo the square root:
This matches choice C.
Xy 14
x + y = -4
x + y = -4
x - x + y = -x - 4
y = -x - 4
xy = 14
x(-x - 4) = 14
x(-x) - x(4) = 14
-x² - 4x = 14
-x² - 4x - 14 = 0
-1(x²) - 1(4x) - 1(14) = 0
-1(x² + 4x + 14) = 0
-1 -1
x² + 4x + 14 = 0
x = -(4) ± √((4)² - 4(1)(14))
2(1)
x = -4 ± √(16 - 56)

x = -4 ± √(-40)

x = -4 ± 2i√(10)

x = -2 ± i√(10)
x + y = -4
-2 ± i√(10) + y = -4
- (-2 ± i√(10)) - (-2 ± i√(10))
y = -2 ± i√(10)
(x, y) = (-2 ± √(10), -2 ± √(10))
The two numbers that multiply to 14 and add up to -4 are -2 ± i√(10).
