Answer:
Step-by-step explanation:
The given line passes through points (−3, 2) and (2, 1).
We use the formula 
to find the slope of this line.
We use the point slope formula:
We expand to get:
The slope intercept form of the line is:
To find the total increase, we will subtract -14 from 36.
36--14=50
(A double negative is a positive.)
50 is your final answer.
The described picture frame can be visualized into two separate parts. The first area is equal to the area using the outermost dimensions for the length and width.
Area = Length x Height
Area = (20 in) x (14 in)
Area = 280 in²
We are given that the area is only equal to 192 in². We subtract this value from the computed area.
Difference = 280 in² - 192 in²
difference = 88 in²
This area is equal to the area of the hollow space inside the frame. That is equal to,
height = 20 in - 2x
length = 14 in - 2x
The area,
88 = (20 - 2x)(14 - 2x)
Simplify the right hand side of the equation.
88 = 280 - 68x + 4x²
Divide the equation by 4,
22 = 70 - 17x + x²
Transposing,
x² - 17x - 48 = 0
The factors of the equation is 58.2.
Thus, the thickenss is equal to 58.2 in
1 1/16 is it's simplest form.
3/10
As you know the answer already I don't think you need any further explanation :)
