Answer:
John can use no more than 2 GB of additional data
Step-by-step explanation:
Monthly fee = $40
Additional fee = $15 for each 1 GB of data (rounded up) over his 8 GB.
Let x be the number of additional data in GB over his 8 GB of data that comes with his plan.
Total monthly charge is
It is given that monthly charge before taxes to be at most $70.
Divide both sides by 2.
Therefore, John can use no more than 2 GB of additional data.

Answer:
(x,y) = (8,7)
Step-by-step explanation:
Solve equation [2] for the variable x
[2] x = y + 15
Plug this in for variable x in equation [1]
[1] (y +15) + y = 1
[1] 2y = -14
Solve equation [1] for the variable y
[1] 2y = - 14
[1] y = - 7 By now we know this much :
x = y+15
y = -7
// Use the y value to solve for x
x = (-7)+15 = 8
Solution :
{x,y} = {8,-7}
Answer:
His rate of change is 7 pounds per week.
Step-by-step explanation:
Rate of change = change in weight ÷ change in time
change in weight = 188 - 167 = 21 pounds
change in time = 6 - 3 = 3 weeks
Rate of change = 21 ÷ 3 = 7 pounds/week
