Compose the result function for 400 by replacing the function designators with the actual functions 400
The slope of a line is simply a ratio of the change in y-value to the change in x-value
Change in y = y₂ - y₁
= 12 - (-6) = 18
Change in x = x₂ - x₁
= 6 - 3 = 3
Ratio of change in y to change in x = 18/3 = 6
The slope is 6

Step-by-step explanation:
![8 \log_5 x^5\\\\=8(5) \log_5 x~~~~~~~~~~~~~~~~~~~~;[\log_b m^n = n \log_b m]\\\\=40 \log_5 x](https://tex.z-dn.net/?f=8%20%5Clog_5%20x%5E5%5C%5C%5C%5C%3D8%285%29%20%5Clog_5%20x~~~~~~~~~~~~~~~~~~~~%3B%5B%5Clog_b%20m%5En%20%3D%20n%20%5Clog_b%20m%5D%5C%5C%5C%5C%3D40%20%5Clog_5%20x)
To get an average score of 80% (out of four exams), a total of 4*80%=320% is needed, so the minimum required for the 4th test is 320-(75+97+60)=88.
To get an average score of 89% (out of four exams), a total of 4*89%=356% is needed, so the maximum required for the 4th test is 356-(75+97+60)=124, which is impossible.
So the next exam grade must range between 88 and 100 to get a grade b in the class.
