What is it telling us to do- and what do we know?

To find the perimeter of the problem, add all side lengths together.

To find the area, add all the areas of the piece together.

Imagine your taking the piece apart.

Find the area of each separate piece.

to find the width of c and d, divide 70 by 14. That = 5

There are five separate widths-b- c- d and all in between, so we can safely assume each width is 14.

To find the area of b, multiply 50-12 by 14. 38*14=542

To find the area of c, multiply 25 by 14=350

To find the area of d, multiply 50 by 14, because at the top we can see its equal to 50. That =700

Then finally, to find the area of a, multiply 70 by 12 to get 840. Added all together, the total area is 2432.

To find the perimeter, we take all the data we've gathered about the side lengths and add it together. The total perimeter is 414.

Hope this helps!

Graph the line that passes through the points (6,-4) and (3,-6) and determine

antoniya [11.8K]

Answer:

$y = \frac23x - 8$

Step-by-step explanation:

Hello!

First, let's plot the points and draw a straight line through them (image).

Remember that a coordinate is given in the format of (x,y).

<h3 /><h3>Parts of a Line</h3>

Equation format: $y = mx + b$

m = slope
b = y-intercept

The slope is how the graph changes in y as it does in x. Given our two points, the graph rises 2 units and runs 3. That means that the slope is $\frac23$ .

$y = \frac23x + b$

The y-intercept is the intersection of the graph and the y-axis. The intersection takes place at y = -8, so the y-intercept is -8.

$y = \frac23x - 8$

The equation is $y = \frac23x - 8$ .

The graph below shows a company's profit f(x), in dollars, depending on the price of pens x, in dollars, sold by the company:

Volgvan

The answers to the various part as well as its reasons are given below

The x-intercepts shows a zero profit.
The maximum value of the graph tells or depict the maximum profit.
The function is one that goes up or increases upward until it reach the vertex and then it falls or decreases after it.
This implies that the profit goes up as it reaches the peak at the vertex and it goes down after the vertex up until it gets to zero.
The profits are negative as seen on the left of the first zero and on the right of the second zero.

An approximate average rate of change of the graph from x = 3 to x = 5, shows the reduction in profit from 3 to 5.

Based on the above, the domain is one that is held back or constrained by x = 0 .

We are compelled at x = 6 due to the fact that we have to maneuver a negative profit.
