Answer:
Ben needs to get a 99% on his second test
Step-by-step explanation:
The average is the sum of both test scores, divided by the total number of test scores (2).
Let x by the grade Ben must receive on his second test.
(89 + x)/2 = 94
Multiply by 2 on both sides
89 + x = 188
Subtract 89 on both sides
x = 99
Check work:
(89 + 99)/2 = 188/2 = 99
The answer is (6,9) because of the slope given . you put it in stat edit. i just made this up so i can complete the first steps of signing up.
15y -8y + 12 = -3
7y = - 15
y = -15/7
or
y = 2.1
D there is really no solution unless u get the value of x which I do not have so it can only be simplified into this equation above I hope this is correct and helpful
