Answer:
m = 1/3x
Step-by-step explanation:
slope = y^2 - y^1 / x^2 - x^1
m = 4 - 5 / 3 - 6
m = -1 / -3
m = 1/3
m = 1/3x --> the slope
The sum of the complex number 12 – 5i and –3 + 4i is 9 - i
<h3>How to sum complex number?</h3>
The sum of 12 – 5i and –3 + 4i can be done as follows:
Therefore,
12 - 5I + (-3 + 4i)
12 - 5i - 3 + 4i
Hence,
combine like terms
12 - 3 - 5i + 4i
Finally,
9 - i

Step-by-step explanation:
Assuming the readable scores are:
100, 82, 95, __ , 90, 81, 75, 83, __
We know the mean (or average) is 85, so:
85 = (100 + 82 + 95 + x + 90 + 81 + 75 + 83 + y) / 9
765 = 606 + x + y
159 = x + y
We know the lowest score is 75, so x and y must be at least 76. Possible answers are:
76 and 83
77 and 82
78 and 81
79 and 80
80 and 79
81 and 78
82 and 77
83 and 76
38 is 76% of 50 hope this helps:)
