Well given these 2 pieces of information, we can easily obtain the equation for the line which would be the following :
Y = 5x - 1.
The 4 points including the y intercept:
(0,-1)
(1,4)
(2,9)
(3,14).
Say the width is W and the length is L
L=3W (and of course W=W)
Now you use the perimeter formula P=2L+2W
80=2(3W) + 2W)
80=6W+2W
80=8W Divide both sides by 8
W=10
Now that you know the width, substitute it back into L=3W to find the length
L=3(10)
L=30
The dimensions are length: 30 cm and width: 10 cm
Answer:
The hours times 4 equals the miles. The answer is B.
Step-by-step explanation:
Plug in any value for x and then you will get y. Use the coordinates to plot.
Example
x= 2
5/2(2)-6
5-6
-1
(2,-1)
Then continue to do the same.
