Suppose there is a rectangle with a width and length of x and y. The area would be xy.
A rectangle with width and length 2x and 2y would have an area of 4xy.
In essence, when you multiply the lengths by 2, the area multiplies by 2 SQUARED.
4(4(x+3)) = 16(x+3).
The ratio will be the same for any value of x because the area is still being multiplied by the same 2².
The graph is attached in the figure below.
Step-by-step explanation:
To graph a point we perform the following steps.
- Consider point J(-5,2.5)
- Here x = -5, and y = 2.5
- Find -5 in x axis and 2.5 in y-axis. the point where both meet is the point for J on graph.
All other points are also drawn in the graph following the above steps.
The graph is attached in the figure below.

Answer:
x = 10
y = 9
Step-by-step explanation:
First, you need to write two equations that represent the information given. I'm going to set the two numbers and x and y.
x - y = 1
x + y = 19
This turns it into a systems of equations. When you add the two equations, keeping everything on each side, you eliminate a variable, and solve for the other.
2x = 20
x = 10
Now, you'd plug x into either original equation.
(10) - y = 1
-y = -9
x = 10
I hope this helped!
Answer:
9
Step-by-step explanation:
81= 1,3,9,27,81
72= 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36,72
9 is the most common so GCF will be 9.
The answer will be -8
y=8-2x x=8
8-2(8)
8-16=-8
