<span>A tutor charges $40 plus $2/minute to do algebra homework.
Cost = 2*x + 40, where x is the number of minutes.

Answer:
closed circle on -9 and shaded to the right
Step-by-step explanation:
Since it has "≥", the circle would be closed.
Now, it states that "x is greater than or equal to -9"
So that means x would be positive and would start at -9.
Since x is unknown, the line would extend to the right side(positive side).
Answer:
9 times
Step-by-step explanation:
first you do 14 - 2.75 which equals 11.25. you divide that number by 1.25 which equals 9 in total, getting you your answer
One answer is 2 it makes each of the sides 12
-47 - 15y =-17.....Equation A
-x+ 5y=-13..........Equation B
Solve B for y.
-x + 5y = -13
5y = x - 13
y = (x - 13)/5
Plug y into A.
-47 -15y = -17
-47 -15(x - 13)/5 = -17
-47 -3(x - 13) = -17
-47 -3x + 39 = -17
-3x - 8 = -17
-3x = -17 + 8
-3x = -9
x = -9/-3
x = 3
Now that we know x is 3, plug 3 for x into EITHER Equation A or B (your choice) to find y.
I will let you do that.
