Photo please? and a function means that it cant have the same number of x axis'
example,
function;
15 6
-46 37
36 -37
27 -25
not a function;
-1 3
5 7
-5 6
-1 8
7+3x=2x+2
Send constants to one side and others to one side
3x-2x=2-7
x=-5
Remember
i²=-1 so
i³=-i
i⁴=1
so
5i⁴+2i³+8i²-4
5(1)+2(-i)+8(-1)-4
5-2i-8-4
-7-2i is the form
The straight angle ;
60 + x = 180
So x = 120
Please give me a brainliest answer
