Answer:
The answers to your questions are:
a) x = 14
b) x = 25
Step-by-step explanation:
a) (7x -1) + (6x -1) = 180
7x -1 + 6x -1 = 180
7x + 6x = 180 + 1 +1
13x = 182
x = 182/13
x = 14
b) 5x +4 = 8x - 71
8x - 71 = 5x + 4
8x - 5x = 71 + 4
3 x = 75
x = 75 / 3
x = 25
For two lines to be parallel, their slope must be the same.
To find the slope, we can use the form:
For the top line, the change in height (y value) can be seen as a - 0 or simply a, and the change in base is just -b (because our
is just 0, from the origin.
Hence, line 1's gradient is:
Now, we can repeat this process for line 2:
Change in height is -d, change in base is c
Hence, line 2's gradient is:
For the two lines to be parallel, both gradients must be the same:
Okay, so for the discount rate let's first make 15% to a decimal. 15% as a decimal is 0.15 and 82.95-0.15=82.80. Therefore, that is the price of the bike with the discount. There's no need to round to the nearest cent I don't think because 80 is a solid number. Hope this helped!
Answer:
Invoice price
Step-by-step explanation:
The actual price paid to the manufacturer or distributor by the end-customer retailer, which is known as the invoice price. However, in many industries, the "invoice cost" actually varies from the "net purchase cost," or the actual price of a product. -Wikipedia (I am not sponsoring I am stating my source)
