Answer:
Step-by-step explanation:
x=-2, x=3
---------------
x^2+5x+6=(-2)^2+5(-2)+6=(-2)(-2)-10+6=4-10+6=-6+6=0
x^2+5x+6=3^2+5(3)+6=9+15+6=24+6=30
---------------------------------------------------------------
x^2-x-6=(-2)^2-(-2)-6=4+2-6=6-6=0
x^2-x-6=3^2-3-6=9-3-6=6-6=0
-----------------------------------------------------
(-5)+13 = 8
-9+1=8

Answer:
ok so it would be square root 2
Step-by-step explanation:
Answer:
x=-1/2, y=1/6
Step-by-step explanation:
Use system of equations.
(5x – 3y = -3) *2 to get:
(10x-6y=-6)
+2x + 6y = 0
12x=-6
x=-1/2
Use either equation to find y with the x value we just found.
5(-1/2)-3y=-3
(-5/2)-3y=-3
-3y=-3+(5/2)=(-6/2)+(5/2)
-3y=(-1/2)
y=(-1/2)/(-3)
y=1/6
You can also check this on graphing websites to see where they intersect.
Sin=opposite side/hypotenuse
cos=adjacent side/hypotenuse
tan=sin/cos or opposite/adjacent
