Hey there!

The difference is that y = kx means the "y directly varies with x", which means that y/x = k. Also, the line of the graph passes directly through the origin. Or, in other words, there is no y - intercept other than (0, 0)

y = mx could have a y - intercept not at the origin. If you have an equation in slope - intercept form, such as y = 5x + 3, than "y" does not directly vary with "x", because you can't get "m" by doing y/x, because first you have to subtract 3. In order to actually find "m", you would have to do (y - 3) / x = m (or, in this case, 5).

Hope this helps! Good luck and have a great day!

We can compare y = kx to the slope-intercept form of a line, y = mx + b.

We can see that y = kx is a linear equation with slope k and y-intercept 0.

For a special sale, a mens tie buyer plans to promote a $39.99 tie. Consequently, the buyer purchases 450 ties and wants to achi
zlopas [31]

Answer:

The average cost of each tie is $56.350

Step-by-step explanation:

We are given that a men tie buyer plans to promote a $39.99 tie. Consequently, the buyer purchases 450 ties

So, Cost of 450 ties = 450 \times 39.99=17995.5

An order for 100 ties that cost $20.00 each

Cost of 100 ties = 100 \times 20 = 2000

Total cost price = 17995.5+2000 = 19995.5

Let the selling price of 1 tie be x

Total ties = 450+100 = 550

So, SP of 550 ties =550x

Now we are given that markup is 55%

So, Profit % = 55%

So, CP = \frac{SP \times 100}{100+P\%}

Substitute the values

19995.5 = \frac{550x \times 100}{100+55}

19995.5 = \frac{550x \times 100}{155}

19995.5 \times 155 = 55000x

\frac{19995.5 \times 155}{55000}=x

56.350=x

Hence The average cost of each tie is $56.350

How many books can you get in a storage bin that is 4 feet high and 9 feet long and 11 feet wide
Ugo [173]
Well, this depends on the size of the books. We can find the volume of the bin by using...
V=bh or l x w x h
So, 9 times 11 is 99.
99 times 4 is 396, which is the volume.
You did not specify the size of the books, so all we can say is that the volume of the bin is 396 cubic feet.

8x+15 = 2x+39

8x =2x+24

6x = 24

x = 24/6 = 4

 angle 4 = 2(4) +39 = 8+39 = 47

 angle 6 = angle 4

angle 6 = 47 degrees
