Answer:
x^2+6x-4=0 x^2+6x=4 x^2+6x+9=13 (x+3)(x+3)=13 x+3=+or-(13^1/2) x=-3+or-13^1/2

Answer:
x = 0, y = -1
Step-by-step explanation:
10x = 5y + 5
y = 2x - 1
======================
10x = 5(2x - 1) + 5
10x = 10x - 5 + 5
x = 0
======================
y = 2x - 1
y = -1
To get the Y values use the equation Y = MX and substitute the X and M values So for the first one you would get Y = -3 x -1 leaving Y as 3 then for the second you do Y = -3 x 0 giving you Y = 0 the third would be Y = -3 x 1 so Y would be -3 and you give the last one a shot >.O best of luck!
