Answer:
w = 12.38
Step-by-step explanation:
w - 2.58 = 9.8
add 2.58 to both sides
w = 12.38
The answer should be -40 + 16i
(0, -2) and (1, 1) both work in this system of equations.
The best way to find if it is a solution is to look for those points on the graph. When you graph the point, it needs to fall in an area where both lines or shaded or on a solid line.
(0, -2) falls on a solid line.
(1, 1) falls in the double shaded area.
4 1/5a-2.2=
4 1/5a=4.2a So,
4.2a-2.2=2a
__________
-1 4/5a+3.8=
-1 4/5a=-1.8a So,
-1.8a+3.8=+5.6
I think that is it!
