Answer:

Step-by-step explanation:
Since the dot in the illustration isn't filled in, that means that x can not be a part of -14, which means it is greater than 14
f(x) = mx + b
m = slope = -5
f(2) = 10 = (-5)(2) + b
b = 10 + 10 = 20
Ans. m=-5, b = 20
The answer has to 2.26 because 2.26 is bigger than 2.25
77+72=149
149/2=74.5
through the process of elimination, I found that Jim needs to get an 88 or higher to receive an average of 79 or greater.
77+72+88=237
237/3=79
6 times (7+5) plus 3 or 6x(7+5)+3
