Jerri's current satellite television service charges a flat rate of 35 dollars per month for the basic channels and an additional 10 dollars per month for each premium. channel. a competing satellite television serive charges a flat rate of 40 dollars per month for the basic channels and an additional 8 dollars per month for each premium channel. a) write an equation in slope intercept form that models the total monthly cost for each satellite service where p is the number of premium channels. b) if jerri wants to include 3 premium channels in her package, which service would be less, her currebt serice or the competing service?

y=10p+35

y=8p+40

y=10*3+35 y=65

y=8*3+40 y=64 (2nd service is cheaper)

Step-by-step explanation:

y=mx+b,

P(x) is the amount of premium channels

b is the flat rate charged for the basic channels

m(slope) is the amount of money for each additional premium channel

Option B is correct.

The relation which has an inverse that is not a function is :(1, 2), (1, 3), (4, 3)

Step-by-step explanation:

Inverse of a function is the set of ordered pairs obtained by interchanging the first and second elements of each pair in the original function.

Let f(x) ={(1, 2), (1, 3), (4, 3)}

To find the inverse:

Inverse of f(x)=g(x)= {(2, 1), (3, 1), (3, 4)}

Function states that a relation in which each input value has only one output value.

Since, g(x) is not a function because the input 3 has multiple output values,.

Therefore, the only relation which has an inverse that is not a function is :(1, 2), (1, 3), (4, 3)
