If comparing x^2 to x^3, which value of x gives the greatest difference:x=6,x=8,x=10?
VMariaS [17]

Answer:

the value of x that gives the greatest difference is 10.

Step-by-step explanation:

Given;

x² and x³

values of x = 6, 8 and 10

When x = 6

6³ - 6² = 216 - 36 = 180

When x = 8

8³ - 8² = 512 - 64 = 448

When x = 10

10³ - 10² = 1000 - 100 = 900

Therefore, the value of x that gives the greatest difference is 10.

Cell Phone Company A charges $20 each month plus $0.03 per text. Cell Phone Company B charges $5 each month plus $0.07 per text.
Ymorist [56]
Cost of company A=monthlyfee+text=20+0.03t where t=number of texts
A=20+0.03t

company b is monthlyfee+texts=5+0.07t
B=5+0.07t



1.
c=20+0.03t
c=5+0.07t
using c for cost is confusing because we can't tell which is for which company



2.

equal, means the costs are equal so
20+0.03t=5+0.07t
minus 5 from both sides
15+0.03t=0.07t
minus 0.03t from both sides
15=0.04t
divide both sides by 0.04
375=t
the answer is 375 texts
