The line perpendicular to x = 2 will be y = something. This line passes through (0,-4) so its equation is y = -4 (answer)
X=20. Hoped this helped! If you need an explanation ask away....
y=3x-2 y=-2x+8
3x-2=-2x+8 (plus 2 each side)
3x=-2x+6 (plus 2x each side)
5x=6 (divide by 5 each side)
x=1.2
Plug x back into an equation
y=3(1.2)-2
y=3.6-2
y=1.6
Answer: (1.2, 1.6)
The correct answer for this question is 4.
We have to bear in mind that any number should be less than 5 to make the square root be an imaginary number.
Starting with 4
= square root (4 - 5)
= square root (-1)
= imaginary
