Answer:
x = ± 2i
Step-by-step explanation:
The equation has no real roots, gut has complex roots
Given
x² = - 4 ( take the square root of both sides )
x = ± 
= ± 
[ Note that
= i ]
= ±
×
= ± 2i
C
because you just eliminate it
Answer:
A
Step-by-step explanation:
So that is a 90 degree angle and there is an angle of 30. 30-90 is 60. 60 divided by 4 is 15. So thus the answer is A,15.
The equation for this would be 41/4 + 52/3 - 41/3= ?
So then you just change all the denominators to their lcm, which is 12 and multiply the numerator accordingly.
123/12 + 208/12 - 164/12 = 167/12
<h3>
<u>Explanation</u></h3>
- Given two coordinate points.

- Calculate and find the slope by using rise over run formula with two given points.

Substitute the coordinate points in.

Hence, the value of m is - 1/3.
