Create the expression:
x^2 = 100
Take the square root of both sides:
x = 10
Answer:
-7/9
Step-by-step explanation:
the slope of a line between two points is 'rise over run', or the vertical distance between the points divided by the horizontal distance between them.
Finding the change in either direction is done by simply subracting our starting value from our ending value. It does not matter which point you start at, but lets choose (-6,-7) as our starting point, and (-24,7) as our end point.
The 'rise' of this line is 7 - (-7), which equals 14
The 'run' would then be -24 - (-6), which equals -18
Thus the slope is 14/(-18). Reducing this fraction gives us an answer of -7/9.
First you to eliminate i from denominator.
mult by (7+3i) above and below
=(49+42i-9)/(49-9)
which is (40+42i)/40 which can simplify
