Hello from MrBillDoesMath!

Answer:

Leftmost graph:    x<= -2         or   ( minus infinity, -2]

Middle    graph:    (-5, infinity)

Right       graph:   (-2, 3)

Discussion:

I n the graphs the white circle means that value is NOT included in the set. For example, In the Right graph the values -2 and +3 (the "endpoints") are NOT included in the solution set.

In graphs ")" means the value is NOT included but "]"  (the square bracket)  means the value IS included.


Regards,  

MrB

 P.S.  I'll be on vacation from Friday, Dec 22 to Jan 2, 2019. Have a Great New Year!

Circle A has a radius of 21 meters . Circle B has a radius of 28 meters. Find the circumference if each circle in terms of pi
qwelly [4]

Answer:

Circle A= 42\pi

Circle B =56\pi

Step-by-step explanation:

Circumference of a circle =2\pi r

Since you are given the radius, you put it in place of r

Circle A = 2 *\pi *28\\21*2 = 42\\\\42\pi

                                            Circle B= \\2*\pi *28\\28*2 =56\\56\pi\\\\\\

Sal's Sandwich Shop sells wraps and sandwiches as part of its lunch specials. The profit on every sandwich is $2, and the profit
kap26 [50]
1.) the y intercept is 490 and the slope is -2/3x
2.) First, I would find the point (0,490) and plot a point there. Then I would use our slope -2/3 to figure out what direction and what angle the line goes by counting 2 down and 3 to the right
3.) f(x)= -2/3x+490
The graph represents how many wraps could've been sold for each number of sandwich sales to keep the same profit of $1,470.
4.) graph down below
5.) the profits are the same (slope) but the y intercept is higher then the original graph.
6.) y=-2/3x+300
