Answer:
Step-by-step explanation:
Let
x ----> the number of minutes
y ----> the total charge in dollars
we know that
For x>700 min
so
For y=48.10
substitute
Multiply by 100 both sides
----> equation without decimals
solve for x
To find out the total minutes we need to sum
Answer:
D: All real numbers
R: All real numbers
Step-by-step explanation:
Another way to put this would be (-∞, ∞) for both, but your teacher has asked for the word statement. The reason it's all real numbers is because both the domain and range continue on forever. There's no ending point.

Answer:
27.73
Step-by-step explanation:

23.73+ 4.00= 27.73
Answer:
(0,-1),(2,5)
Step-by-step explanation:
3x-y=1
0.5+2x-1=y
Substitute the equation of y into the other equation
3x-(0.5+2x-1)=1
3x-0.5-2x+1=1
collect like terms
-0.5+x=0
Solve for x
x(-0.5x+1)=0
0=-0.5x+1
-1=-0.5x
x=2 x=0
Back substitute into the other original equation and solve for y
3(2)-y=1
6-y=1
y=5
(2,5)
3(0)-y=1
-1(-y)=-1(1)
y=-1
(0,-1)
