Answer:

The vertices are the following intersection points:

1) y = 0 and x 0 0 => (0,0)

2) x = 0 and 2x - 6y = - 3 => (0, 1/2) = (0, 0.5)

3) 2x + 3y = 6 and 2x - 6y = - 3 => (3/2, 1) = (1.5, 1)

4) y = 0 and 2x + 3y = 6 => (3,0)

Answer: (0,0) , (0, 0.5) (1.5, 1), (3, 0) = the third option.

D

your welcome.

5x+2y=20

Substitute 0.3 for x

5(0.3)+2y=20

Multiply 5 by 0.3

1.5+2y=20

Subtract 1.5 from both sides

2y=18.5

Divide 2 on both sides

Final Answer: y= 9.25

Let car b be travelling at x mph. as they are travelling towards each other their speed of approach is (x + x + 15 ) mph. So we have the equation

speed = distance / time

2x + 15 = 250 / 2

2x = 125 - 15 = 110

x = 55 mph

Car b travels at 55 mph and car a travels at 70 mph Answer
