The y-intercept is -5 and the slope is zero.

here is a link to a graph I made that shows this graph

https://www.desmos.com/calculator/moychqhke9

You see when the line crosses the y-axis which is the line in the middle, that is the y-intercept. in the graph it crosses the y-axis when it's y-value is negative 5. The slope is zero because there is no change in it going up or down. As you can see the line remains flat which gives it this slope of zero.

Hope that helps!

Thought of another one: 76923

Multiples: 

$\begin{matrix} 1 && 076923 \\ 10 && 769230 \\ 9 && 692307 \\ 12 && 923076 \\ 3 && 230769 \\ 4 && 307692 \end{matrix} \: \& \: \begin{matrix} 2 && 153846 \\ 7 && 538461 \\ 5 && 384615 \\ 11 && 846153 \\ 6 && 461538 \\ 8 && 615384 \end{matrix}$

1 1/5   /    3

1  1/5  =  6/5  

3  =  15/5     

So we have

 6

 5                                                                    

__         =  "cancel" the denominators          6    =      2

B = 2 (120) - 227  =  240 - 227  =  13°

C =  120/2 + 13  =  60 + 13  =  73°

Let P be the original price

So...taking 20% off = .20P

So

P  - .20P  = "a"

P ( 1 - .20)  =  "a"

P (.80)  = "a"      divide both sides by .80

P  = "a"  /  .80

That doesn't seem right... why would it be 5a? I think it is either $1.25 or $\frac{5a}{4}$dollars. A 20% disount reduces the price to 80% of the original cost, not 20%!

240 / 4  =  60

So.....each side of the triangle on land will be  60  times the length of the side in the photo.

the longest side  =  9 * 60  =  540 m

the middle side  =  6 * 50  =  360 m

(Also.....do notice that the units are different, but it'll work out like this.)

THANK YOU MUCH!!!

a = 7^2 - 1^2   =   49 - 1   = 48

b = 2(7)(1)  =  14

c = 7^2 + 1^2  =  49 + 1  = 50

a/.2

or

1/.2=2

it might be either of these depending on what you meant. I didn't understand if you meant a dollars as in a is a variable, or as a dollars as in 1 dollar.

If you meant a as a variable it is a/.2. 

if you meant a as in 1 it is 1/.2=2

Hope this helped!

√3sec (3θ) -  2  = 0   add 2 to each side

√3sec (3θ)  =   2        divide both sides by  √3

sec (3θ )  =  2  / √3

Let q  =  3θ

sec (q)   = 2  / √3

And this happens when cos (q)  = √3 / 2    .....so....

q  =  30°,  330°, 390°, 690°, 750°, 1050° , 1110°, 1410°, 1470°, 1770°, 1830°, 2130° 

So  3θ  =   30°,  330°, 390°, 690°, 750°, 1050°, 1110°, 1410°, 1470°, 1770°, 1830°, 2130° 

Divide each side by 3

θ  =  10°, 110°, 130°, 230°, 250°, 350°, 370°, 470°, 490°, 590°, 610°, 710°

Here's the graph :  https://www.desmos.com/calculator/yj6jsij1kc

Notice that the side length of the square is  38 m.

area of square  =  (side length)²  =  (38 m)²   =   1444 m²

Notice that the diameter of the circle is  38 m .

And its radius  =  diameter / 2   =   38m / 2   =   19 m

area of circle  =  pi * radius²  =  pi * (19m)²  =  pi * 361 m²   ≈   1133.54 m²

So......

area of shaded region  =  area of square - area of circle

area of shaded region  ≈       1444 m²     -  1133.54 m²

area of shaded region  ≈    310.46 m²

Wow! Tha's really cool! Do you have any more?

Situation 1: Robert has $1\frac{1}{5}$ cups of fresh popcorn kernels stored in a jar, but the capacity of his popcorn machine maker is a third of the amount of popcorn kernels at a time. 

In this case, $\frac{1\frac{1}{5}}{3}$ represents the capacity, in cups, of the popcorn machine maker.

Situation 2: Robert estimates that his homework for math, science, and history will take $1\frac{1}{5}$ hours to complete. He plans to make this homework load more manageable by working on each subject for an equal amount of time. 

In this scenario. $\frac{1\frac{1}{5}}{3}$ hours represents the amount of time he plans to work on each subject.

$1\frac15\div3$

Convert  1 and 1/5  into a single fraction.

$=(1+\frac15)\div3 \\~\\ =(\frac55+\frac15)\div3\\~\\ =\frac65\div3$

Now we can just divide like this...

$=\frac{6\div3}5 \\~\\ =\frac25$

m∠V  =  20°

m∠X  =  83°

△TVW  is similar to  △XYZ  .     So...

m∠T  =  m∠X  =  83°

So we know two of the angles in  △TVW :   m∠T = 83°     and     m∠V = 20° .

Since the sum of the angles in any triangle  =  180° ,

the third angle in  △TVW ,   m∠W  =  180° - 83° - 20°  =  77°

m∠W  =  77°

Again,  △TVW  is similar to  △XYZ  .     So...

m∠Y  =  m∠V  =  20°

m∠Z  =  m∠W  =  77°

The measure of angle B is

The measure of angle C is

Look at the first line of CPhill's answer......  

can someone answer the bottom question?

2x + 4y  =  22

2x - 2y  =  14

Multiply the second equation through by  2 . So the two equations become:

2x + 4y  =  22

4x - 4y  =  28

Now add the two equations together to get...

6x + 0  =  50

6x  =  50          Divide both sides of this equation by  6 .

x  =  25/3

Now lets plug this value for  x  back into one of the equations to find  y .

2(25/3) + 4y  =  22         Multiply  2(25/3)  to get  50/3 .

50/3 + 4y  =  22              Subtract  50/3  from both sides of this equation.

4y  =  22 - 50/3

4y  =  16/3                      Divide both sides by  4 .

y  =  4/3

(1/2)  / 5   =

(1/2)  /  (5 / 1)  =

(1/2) * (1 / 5)   =

1 / 10

2x+4y=22

2x-2y=14

We need two equations in order to use elimination....
