If you have any more questions feel free to ask in the comments!
Hope this helps!!!
Sure what do you need help on
Answer:

Step-by-step explanation:
A linear function has the following format:

In which a is the slope(rate of change) and b is the y-intercept, that is, the value of y when x = 0.
Rate of change of 3
This means that 
So

A solution at (6, 12).
This means that when x = 6, y = 12. So



The linear function is:

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
Answer: angle B will be 90°
Sum of the angles = 180°
