Answer:
f (x) = { 19 + 0.39(x - 300), x > 300
Step-by-step explanation:
Andrew has a cell phone plan that provides 300 free minutes each month for a flat rate of $19. For any minutes over 300, Andrew is charged $0.39 per minute. Let x be the number of minutes Andrew uses per month and f(x) be the charges based on Andrew's cell phone plan. If then If then first 300 minutes are free and each minute of next (x-300) minutes costs $0.39, therefore Hence, { 19 + 0.39(x - 300), x > 300

Answer:
Hi there!
Your answer is:
Small number = 20
Larger number = 77
Step-by-step explanation:
larger= 4s-3
smaller = s
s+ 4s-3 = 97
5s-3 = 97
+3
5s = 100
/5
s= 20
large number = 4(20)-3
80-3
larger = 77
Double check work!
20+77= 97✓
Hope this helps!
Answer: i didnt understand the answer choice but the correct answer is 48/12=width. width=4
Step-by-step explanation:
as we know the area of a rectangle is area=length X width
so we plug in 48 as area and 12 as length
48=12 x width
48/12=width(divide both sides by 12)
The degree of a polynomial is the largest exponent on the variable.
For the given problem there is only one term with an exponent: 5x^2.
The exponent is 2, so the degree would be 2.
