Answer:
y = 4
Step-by-step explanation:
y = 4
The line will always go along y = 4 and therefore is parallel to the x axis
X²+20=0
x=±√(-80)/2
x=±4i√5/2=2i√5
factorised it is then
(x+2i√5)*(x-2i√5)
Answer:
6=y
Step-by-step explanation:
5y + 6 = -3y +54
isolate y
+3y
8y +6 =54
subtract 6 to isolate y.
8y = 48
divide by 8 so y is alone w no coefficient other than 1
y=6
