Answer:

1. y=0.35x+35

2. If 979 minutes are used, the total cost will be $377.65 dollars.

Step-by-step explanation:

1. Let $x be the flat monthly fee and $y be the amount of money paid per minute used on the phone.

If a customer uses 210 minutes, the monthly cost will be $108.5, thus

x+210y=108.5

If the customer uses 620 minutes, the monthly cost will be $252, then

x+620y=252

Subtract from the second equation the first one:

x+620y-(x+210y)=252-108.5\\ \\x+620y-x-210y=143.5\\ \\410y=143.5\\ \\y=0.35

Substitute it into the first equation

x+210\cdot 0.35=108.5\\ \\x=108.5-73.5\\ \\x=35

We get the flat fee is $35 and the amount of money per minure used is $0.35. So, the equation of the function is

y=35+0.35x,

where x is the number of monthly minutes used and y is the total monthly of the NextFell plan.

2. When x=979, then

y=35+0.35\cdot 979=377.65

Can anyone please help me?​
Yanka [14]

Answer:

B.

Step-by-step explanation:

Parentheses mean multiplication in this case. So it would be 2 x -3 OR -3 + -3. When multiplying a negative and a positive the answer will ALWAYS be negative. So you would move to the left on a number line.

If x = 2 calculate the value of x squared- x
monitta
Plug the x value which is 2 back to the x and solve.

I gave you two answers because I wasn’t sure if the question was (x^2) - 2 or x^2-2.
Those two functions look similar but is totally different so keep that in mind.

Hope you have a victorious day!
