Answer:
y = -3x + 4
Step-by-step explanation:
sorry im late
but all you have to do is isolate the y
so to do that we have to get rid of the 3x
3x + y = 4
in order to do that we have to subtract 3x from both sides of the equal sign since it is positive and being added to the y
3x + y = 4
-3x -3x
y = -3x + 4
and now y is isolated
Answer:
- 84 + 10i
Step-by-step explanation:
A complex number in standard form is a ± bi
a is the real part and bi the imaginary part
and
= i
Given
- 84
=
- 84
=
×
- 84
= 10i - 84
= - 84 + 10i ← in standard form
