Answer:
D) all real numbers
Step-by-step explanation:
The domain is all real numbers because the graph continues to the left and right infinitely.
Answer:
(-10, 0) and (0,-5)
Step-by-step explanation:
For the function
find x-intercept and y-intercept:
1. when y=0, then

2. when x=0, then

You get two points (-10, 0) and (0,-5). Plot them on the coordinate plane and connect, obtained line is the graph of the linear function 
Answer:
-8x=19-3
-8x=16
x= 16/-8
x=-2
Step-by-step explanation:
The distance flown by plane is 750 kilometers.
Step-by-step explanation:
Let,
Distance traveled by plane = x
Distance traveled by car = y
Total distance = x+y
According to given statement;
The distance by car was 125 kilometers less than the distance by plane.
y = x - 125 => x=y+125 Eqn 1
The total distance was 500 kilometers less than three times the distance traveled by car.
Total distance = 3y - 500
x+y=3y-500 Eqn 2
Putting value of x from Eqn 1;

Putting y=625 in Eqn 1

The distance flown by plane is 750 kilometers.
