Find the area of this figure (50 points)
Softa [21]

Answer:

A_{total} = 14\ in^2

Step-by-step explanation:

<u>Step 1:  Determine the area of the left rectangle</u>

We can tell that the total shape seems like two rectangles glued together.  We can separate the left rectangle and determine the area of it and then determine the area of the right rectangle and combine them.  Lets first solve the left rectangle.

A = l * w

A_{left\ rectangle} = 2\ in * 4\ in

A_{left\ rectangle}  = 8\ in^2

<u>Step 2:  Determine the area of the right rectangle</u>

A = l * w

A_{right\ rectangle} = 3\ in * 2\ in

A_{right\ rectangle} = 6\ in^2

<u>Step 3:  Determine the total area</u>

A_{total}=A_{left\ rectangle} + A_{right\ rectangle}

A_{total} =  8\ in^2 +  6\ in^2

A_{total} = 14\ in^2

Answer: A_{total} = 14\ in^2

What’s the slope of this graph? Can y’all guys help please ! Thank y’all
Anvisha [2.4K]

Answer:

3

Step-by-step explanation:

we can think of the <em>slope</em> of a graph as \frac{rise}{run}

the "rise" is the difference in y-values between two points (the change in y)

the "run" is the difference in x-values between two points (the change in x)

when we divide these (rise/run), we find the slope

you can choose any two well-defined points (with clear x and y values), here are the two we will be using:

(remember, points are written as (x, y)  )  

(0 , 2)

(-1 , -1)

for the "rise", we have risen 3 (difference between 2 and -1 = 3 [2- -1 = 3] )

for the "run" we have ran 1 (difference between 0 and -1 = 1) (0 - - 1 = 1)

so, the slope for this graph is: 3/1 ; which simplifies to 3

So, the slope of our graph is 3

<em>--------------------------------------------------------------</em>

<em>technical layout:</em>

<em />

m=\frac{y_{2} -y_{1}}{x_{2}-x_{1}}               (note: slope is called "m" in the format of y=mx + b)

y_{1} means one y-value, y_{2} means other y-value

x_{1} means one y-value, x_{2} means other x-value

{note: it is important to keep the y1 and x1 from the same point, and the y2 and x2 from a shared point}

our equation in this layout:

m=\frac{2 -(-1)}{0-(-1)} = m=\frac{3}{1}

                     m = 3
