Answer:
Step-by-step explanation:
A) Let x represent minutes used, and C represent monthly charge. We are given two (x, C) pairs: (370, 133.00) and (530, 181.00)
We can use these in the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
C = (181 -133)/(530 -370)(x -370) +133
C = 48/160(x -370) +133
C = 0.30x -111 +133
C = 0.30x +22
__
B) For x = 477 minutes, the charge will be ...
C = 0.30(477) +22 = $165.10 . . . . for 477 minutes

Answer:
22/24
Step-by-step explanation:
To figure this out, both the numerator and the denominator of the equivalent fraction have to be proportional to 11/12.
To do that, multiply the numerator (11) by 2, (because the denominator of the second fraction is 2 times the denominator of the first fraction).
The second, proportional fraction is 22/24.
Answer:
- The second graph, top right
Step-by-step explanation:
#1, top left
- Has repeating x- values at x = -2, not a function
#2, top right
- No repeat, input or outputs, is a function
#3, bottom left
- Has repeating x- values at x = 0, not a function
#4, bottom right
- Has repeating x- values at x = -1, not a function
