<span>(5 + 3i)(8 - 2i) =
40 - 10i + 24i - 6i</span>² =
40 + 14i - 6(-1) =
40 + 14i + 6 =
46 + 14i
Answer:
r=5
Step-by-step explanation:
1.simplify both sides of the equation.
2.substract 2r from both sides.
3.substract 12 from both sides.
4.multiply both sides by 5/(11)
5. your answer will be 5.
r=5
My answer is 16 cause if you add 10 and 3 and 3 the =16
Answer:
-3
Step-by-step explanation:
A = midpoint
-17 + 5 = -12
-12/2 = -6 = A
-6 + 0 = -6
-6/2 = -3 = B
2. y=2x+3
When x =0 and y= something, the 'something' is your y-intercept which is b in the y=mx+b formula. Then we look at what is changed in the x and y value to determine the m part. the x increase by 1 and y increase by 2 so the m part is 2.
3. y=-7x
Same as the last one, there is no y-inter this time because the y=0 when x=0/ So the y deceased by 7 each time and x incease by 1 so it is -7 for the m part.
