2. AT&T charges $40 for a smartphone with unlimited minutes plus data charges. In addition to the smartphone charges, AT&T charges $20 for up to 2gb of data, $30 for data above 2gb but below 6gb, $40 for data from 6gb up to 10gb, and $40 for any data 10gb and above.
Draw the graph of these fees
2a. How much is your total bill if you use 6.5gb of data?

2b. How much is your total bill if you use 9.5gb of data?

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

i think the answer would be c

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.
