Answer: it will take 5 months for both plans to cost the same.

Step-by-step explanation:

Let x represent the number of months before the cost of the two phones and monthly service fees would be the same.

check sell offers a new phone for $50 and unlimited service for a monthly fee of $40. This means that the total cost of using this plan for x months would be

50 + 40x

cellular offers a new phone and unlimited service for a monthly fee of $50. This means that the total cost of using this plan for x months would be

50x

For both plans to cost the same, the number of months that it will take is

50 + 40x = 50x

50x - 40x = 50

10x = 50

x = 50/10 = 5

Determined to find the slope<br>(1 7K), and (-3,5K)​
Helga [31]

Answer: \dfrac{K}{2} .

Step-by-step explanation:

As we know ,

The slope of a line that passes through (x_1,y_1) and (x_2,y_2)  is given by :

\dfrac{y_2-y_1}{x_2-x_1}

The slope of a line that passes through (1 , 7K), and (-3,5K)​ =

\dfrac{5K-7K}{-3-1}\\\\=\dfrac{-2K}{-4}\\\\=\dfrac{K}{2}

Hence, the slope of the given line is \dfrac{K}{2} .

Find the domain and range of the function y = f(x) = r2.=Domain:help (inequalities)Range:help (inequalities)
Juliette [100K]

we have the function

y=f(x)=x^2

the domain is all real numbers -------> interval (-∞, +∞)

the vertex of the vertical parabola is the origin (0,0)

the parabola opens upward

the vertex is a minimum

so

the range is the interval [0, ∞)
