m = (-1 - 4) /(2-3) = -5/-1 = 5
slope = 5
passing (3, 4)
y = mx + b
4 = 5(3) + b
4 = 15 + b
4 -15 = b
-11 = b or b = -11
answer:
equation
y = 5x - 11
To find the mean, add all the numbers together and divide by the amount of numbers there is
89 + 92 + 97 + 81 + 96 = 455
455/5 = 91
91 is Andrew's mean score, and is your answer
hope this helps
Answer : C
i.e. f(x) =12 when x = 9
Explanation :
Since we have given that
![f(x) =6x^2+2\text{ if} -6](https://tex.z-dn.net/?f=f%28x%29%20%3D6x%5E2%2B2%5Ctext%7B%20if%7D%20-6%3Cx%3C9%5Ctext%7B%20and%20%7D%20f%28x%29%20%3D%2012%20%5Ctext%7B%20if%20%7D9%5Cleq%20x%5Cleq%2013)
x=9 lies in the interval [9,13]
so f(x) will be 12 for x=9
in another interval i.e (-6,9)
x can't be 9 as it is an open interval which does not include 9 .
so we'll go for f(x)=12 when x=9.
