D= 10 Dollars each month
Step-by-step explanation:
You find this answer by subtracting the one time fee of 20 from the total payed of 70, leaving you with 50. You then divide that 50$ by 5 months.
Answer:
y=-x+3
Step-by-step explanation:
The general slope-intercept equation of a line is y=mx+b where m is the slope and b represents the y intercept. y and x are simply a point the line passes through. In this case, y=x-5, meaning m=1 and b=-5.
In order to find the perpendicular slope, we should take the current slope's <u>negative reciprocal</u>. We have:

Therefore, our perpendicular slope is -1. We now have equation:

We can plug in the known values of the point (-1,4) to solve for b.

If we now put what we found together, we have equation

Answer:
x=8
Step-by-step explanation:
3(x+4)=36
Divide each side by 3
3/3 (x+4)=36/3
x+4 = 12
Subtract 4 from each side
x+4-4 = 12-4
x = 8
Answer:
93
Step-by-step explanation:
Add 36 to both sides of the equation:
36 -36 + ___ = 36 +57
0 + ___ = 93
___ = 93
The integer 93 goes in the blank.
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
