Answer:

They need to sell 3 tees, and incurred $60.

Step-by-step explanation:

What is the revenue equation? R = 20x, where x is the # of tees sold.

What is the cost equation? C = 5x + 45, where x is the # of tees sold.

Set those two equations equal, we get:

20x = 5x + 45, 15x = 45, x = 3.

3*5 + 45 = 60.

I need help on which ever one you would like to do :)

Answer:

a. k = n - 1 b. 15 c. 112

Step-by-step explanation:

I can answer a. b. and c. for you!

For a. let's say that the variable k means keys. And n means bits.

Since Millie can collect one less keys than there are bits, the equation is....

*See top*

For b. if Antonio has a 16-bit system, by looking at our equation we know that k = n - 1.

So, if n = 16, k = 15

For c. if each byte equals 8 bits, and there are 14 bytes, then the amount of bits would be 8 x 14.

8 x 14 = 112

True or false: Two lines with undefined slopes are parallel to each other and parallel to the y axis

BlackZzzverrR [31]

Correct! lines that have undefined slopes are always parallel to the y-axis as the change in x is 0. A gradient is calculated by the change in y divided by the change in x and anything divided by 0 is referred to as undefined.

$\frac{y_{1}- y_{2} }{x_{1}- x_{2} }$

(calculation for a gradient)

Hope that helps sorry if its a bit confusing :)
