Step-by-step explanation:
Answer:
See below
Step-by-step explanation:
First, I would choose three different points with some distance between. Let's do x = -5, x = 0, and x = 5. Next, I would plug those numbers into the equation, like so:



Next, I would plot the points [(-5, 45), (0, 25), (5, 5)] on an x-y graph. Finally, I would take a ruler, line it up with the three points, and draw a line through those three points, extending from one side of the graph to the other to show the equation is continuous.
Answer:
3.5 miles
Step-by-step explanation:
Lydia:
3 gallons of gas = 114 miles
We want to know how many miles a friend can travel on one gallon of gas, so we divide both sides by 3
1 gallon of gas = 114/3 miles = 38 miles
Lucy:
One point is
10x corresponds to 415y
10 gallons = 415 miles
divide both sides by 10 to get one gallon on a side
1 gallon = 41.5 miles
Lydia:
38 miles = 1 gallon
Lucy:
41.5 miles = 1 gallon
For 1 gallon, the difference is 3.5 miles, with Lydia having 3.5 miles less than Lucy.
Answer:
Step-by-step explanation:
Given the perimeter of a rectangle P = 80 inches
Let 'x' be the width of a rectangle.
i.e.
x = width
As the length of a rectangle is three times its width. Thus,
length = 3x
We know that perimeter is the sum of all the sides (width and length) of a rectangle. So,
The Perimeter of a rectangle = 2(width + length)
substituting P = 80, width = x, length = 3x
80 = 2(x + 3x)
80 = 2x + 6x
80 = 8x
divide both sides by 8
80/8 = 8x/8
10 = x
Thus, the value of x = 10
Therefore,
The width = x = 10 inches
The length = 3x = 3(10) = 30 inches
Thus,
