<u>Answer:</u>
3x - 2y = 10
<u>Step-by-step explanation:</u>
We are given that the sum of two numbers is 0 and twice the smaller number subtracted from 3 times the larger number is 10.
Assuming x to be the large number and y to be the smaller number we can write an equation to represent this.
Sum of two numbers is 0:

Twice the smaller number subtracted from 3 times the larger number is 10:

If you mean similar as same ratio, the ratio for length to width is 2:1. the width would be 3 inches.
finding the perimeter of rectangles is basically 2L + 2W so the perimeter is 18 inches
Hey!
This could be rewritten as:
2x + 1 + 5x
We can add like terms together:
7x + 1
Since you have not included the plot, I'll just tell you how to find the function of the graph that you are looking for.
Function of the straight line has the general formula: y = mx + c
where:
m is the slope of the line and c is the y-intercept
So first we will need to find the slope (m):
Taking two points from the graph (x1,y1) and (x2,y2), the slope can be calculated as follows:
m = (y2-y2) / (x2-x2)
Then, we will need to find the y intercept.
we have the equation y = mx + c and we have m calculated
Take any point that belongs to the line and substitute with the values of x,y and m and then calculate c.
Now you have both m and c calculated, just substitute with the values in the formula.
Answer:
b squared minus 4ac describes the discriminant which means the amount of solutions that the equation will have.
