Answer:
2-7i is the correct option.
Step-by-step explanation:
We have been given the complex number real part 2 and imaginary part 7 it can be expressed as:
2+7i
And the conjugate means in the complex number is opposite sign of imaginary part that is in general:
a+ib will have conjugate a-ib
So, the conjugate of 2+7i is 2-7i
Hence, Option d is correct.
Answer:9+(7n-3)
Step-by-step explanation: and when n=8, the value of the expression is 62.
Answer:
Step-by-step explanation:
Slopes can be negative, zero, positive or undefined.
A slope that is less than zero is a negative slope, which you see dropping (moving downward) as you move to the right.
The line from the point to its reflection should be perpendicular.If we imagine a line from (5,7) to (2,2), it would have a slope of (2-7)/(2-5) = 5/3.
For that line to be perpendicular to y=-2/5x+6, their slopes should be each other's negative reciprocals.
-2/5 negative reciprocal is 5/2, which is not equal to our calculated 5/3, so (2,2) cannot be the reflected point. Evan was wrong.
Q1-74: AB have slope 6/5, C has -5/6, D 6/5, E -5/6 again.
The answer would definitely be between June-November, because the US is where my aunt lives, and she nearly died! :0
