Answer:

43

Step-by-step explanation:

W = 4B - 1

W + B = 54

4B - 1 + B = 54

5B = 55

B = 11

W = 4(11) - 1

W = 43

Answer: There are 43 white marbles.

Step-by-step explanation:

t = total number of marbles = 54

w = white marbles = 4b - 1

b = blue marbles

54 = b + (4b - 1)

b + 4b = 5b

54 = 5b - 1

+1

55 = 5b

/5

11 = b

There are 11 blue marbles.

4(11) - 1

44 - 1 = 43

43 + 11 = 54, therefore our solutions are correct.

So, the anti derivative= x^2 -.8x +C. Ignore C.
Plug in 2= 4-(2)(.8)=2.4
Plug in .4= .16-(.4)(.8)=-.16

A path 1 m wide is build around a garden that is a 30-meter square. What is the area taken by the path?
Rudik [331]

Answer:

Blue = 116 m^2

Step-by-step explanation:

The area of the path and the square  =  30*30 = 900 m^2

The size of the square = 30 - 2 = 28. The square = 28^2 = 784

The path takes up the difference between the two 900 - 784 = 116

Which equation represents this line in point-slope form?
KiRa [710]

Answer:

The Answer is Option A or Option B

Step-by-step explanation:

First let's review what point slope form is.

y - y 1 = m(x - x1)

To take a line and put it into point slope form you need to identify one of the points. In this case the point is either (-3, -4) or (-3, 4) but <em>without</em><em> </em><em>a</em><em> </em><em>graph</em><em> </em><em>attached</em><em> </em>I cannot personally say which one it is.

You will also need to identify the slope of the line (m) based on the graph, so identify if the graph is ascending or descending. This alone can determine your answer

Again, <em><u>there</u></em><em><u> </u></em><em><u>is</u></em><em><u> </u></em><em><u>no</u></em><em><u> </u></em><em><u>graph</u></em><em><u> </u></em><em><u>provided</u></em><em><u> </u></em> so it is up to you to determine if it is Option A or B.

I really hope this helps and you have a great rest of your day!

Note: I am <em>not</em><em> </em><em>a</em><em> </em><em>professional</em><em> </em><em>educator</em><em> </em>so take my opinion carefully.

=)
