Answer:
The Answer is 2
Step-by-step explanation:
The rule is 4 or less let it rest. 5 or more raise the score. 6 is greater than 5 so you raise it to two
Y = 3x + b
Now plug in points
-7 = 3(-1) + b
-7 = -3 + b
b = -4
The y intercept is -4
-21/10 or -2&1/10 I used my calculator
The average has to be at least 120 and at most 130
To calculate the average we need the sum of all values divided by the number of values, in this case, three (135, 145 and the third result).
120 ≤ (135 + 145 + n)/3 ≤ 130
In inequalities like this, what we change in one side, must be changed in the othe rside as well.
360 ≤ 280 + n ≤ 390
80 ≤ n ≤ 110
