Asmart phone plan has a monthly base fee that includes 5 gigabytes of data. an overage charge is applied when the data usage exceed 5 gigabytes. the equation c = 59 + 15(g − 5) models the plan, where c represents the monthly cost, in dollars, and g represents the total number of gigabytes used for the month. what does the value 15 represent in the equation a: the base fee per month, in dollars, for the plan b: the cost, in dollars, for each additional gigabyte used. c: the average cost, in dollars, for data usage per month. d: the average data usage, in gigabytes, per month

B The cost, in dollars, for each additional gigabyte used.

Step-by-step explanation:

C = 59 + 15(g − 5)

when g=5, C=59 where it is the monthly cost

when g=6, c=59 +15, interpret that each additional gigabyte used will increase the cost for 15

B. The cost, in dollars, for each additional gigabyte used.

Step-by-step explanation:

We are given that,

The equation modeled for the plan is, .

Since, we have that,

The plan has a monthly charge that includes 5 gigabytes of data and over-charge fee for gigabytes exceeding 5 gigabytes.

Thus, when g= 5, C= 59, in dollars.

Also, when g> 5, .

So, we get that,

The expression represents the cost for the additional gigabytes used.

Thus, 15 represents the cost, in dollars, for the additional gigabytes used.

Thus, option B is correct.

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2

answer:   {x = -1/2 ,   y = -1
