Skylar has a smart phone data plan that costs $50 per month that includes 7 GB of data, but will charge an extra $30 per GB over
1 answer:
Answer:
If Skylar went 5 GB over the limit she will have to pay $200 for that month;
If she went "x" GB over the limit, she will have to pay 50 + 30*x.
Step-by-step explanation:
Skylar's plan has a fixed fee of $50 for any value of data usage that is below 7 GB, but charges an extra of $30 per GB over that. For cases where she went over the limit by "x" GB, the cost of her plan is given by:
If she went 5 GB over the limit, she'll have to pay:
She will have to pay $200.

Look at the graph below carefully
Observe the results of shifting ={2}^{x}f(x)=2x
vertically:
The domain, (−∞,∞) remains unchanged.
When the function is shifted up 3 units to ={2}^{x}+3g(x)=2x +3:
The y-intercept shifts up 3 units to (0,4).
The asymptote shifts up 3 units to y=3y=3.
The range becomes (3,∞).
When the function is shifted down 3 units to ={2}^{x}-3h(x)=2 x −3:
The y-intercept shifts down 3 units to (0,−2).
The asymptote also shifts down 3 units to y=-3y=−3.
The range becomes (−3,∞).
