If the cell phone company charges a flat $40 fee monthly, then the equation would be y = 40.
The company does charge $40 a month, but also charges $2 per minute out of service area (x).
So the equation is y = 2x + 40
To graph this linear function, plug in values for x then plot the plots. Then draw a line to connect the points.
y = f(x)
f(0) = 40
f(1) = 42
f(2) = 44
f(3) = 46
f(4) = 48
f(5) = 50
So at x=0, draw a point at y=40 and so on.
1) f/3 + 22 = 17
2) f/3 + 22 - 22 = 17 - 22
= f/3 = -5
3) 3 • f/3 = 3(-5)
= f = 3(-5)
= f = -15
Your answer would be f = -15

Answer:
y intercept = (0,-1.2)
x intercept = (3.6,0)
Step-by-step explanation:
For y-int, x=0
3(0)-9(y)=10.8
9y=-10.8
y= -1.2
For x-int, y =0
3x - 9(0)=10.8
3x=10.8
x=3.6
Answer:
The value of x is 23.
Step-by-step explanation:
5x-20+85=180
5x+65=180
5x=115
x=23
