Answer:
Option (2)
Step-by-step explanation:
Given : y = 
If x = 7i
y = 
By simplifying denominator of the given rational expression,
y = 
y = 
y = 
y =
[Since, i² = (-1)]
y =
y = 
y = 
Therefore, Option (2) is the correct option.
Answer:
3
Step-by-step explanation:
We know x = -2, so we can substitute -2 in for x
3x^2- 9
3*-2^2-9
Solve the exponent first (PEMDAS)
3*4-9
Multiply next
12-9
Subtract
3
Answer:
y = -1/3x + 6
Step-by-step explanation:
the slope is -1/3 because you find the the reciprocal and switch the sign. To find the y intercept you plug in the points to the equation.
5 = -1/3(3) + b
5 = -1 + b
6 = b
