y =mx+b
in the slope intercept form of the equation of a line
m is the slope and b is the y intercept of the line
Answer:
C and D
Step-by-step explanation:
the answers are C and D.
First we have the work out the area of 1 room. So that is 8ft * 12ft which is 96ft^2. And if there are 2 of these rooms, then we multiply this value by 2. Giving us a total area of 192ft^2.

Answers: Choice B and Choice D</h3>
======================================
Work Shown:
c = price of coat before discount
0.33c = discount = amount you save
c - 0.33c = original price minus discount = final price
c - 0.33c = 1c - 0.33c = (1-0.33)c = 0.67c = final price
In short, c - 0.33c = 0.67c
They are two ways of expressing the same thing.
You can think of it like saying 100% - 33% = 67%
If you save 33%, then you still have to pay the remaining 67% of the original cost.
-------------
Example:
Let's say the coat is $100 before the discount
c = 100
0.33*c = 0.33*100 = 33 dollars is how much you save
c - 0.33c = 100 - 33 = 67 dollars is the final price
0.67c = 0.67*100 = 67 matches with the previous figure above
Answer:
A = {3,5,6}
B = {1,3}
<u><em>A x B</em></u> = {(3,1),(3,3),(5,1),(5,3),(6,1),(6,3)}
Domain of A x B = (The x figures in ascending order)
=> {3,5,6} (Figures repeating more than once must be written only 1 time)
Range of A x B = (The y figures in ascending order)
=> {1,3}
<u><em>B x A </em></u>= {(1,3),(3,3),(1,5),(3,5),(1,6),(3,6)}
Domain of B x A = {1,3}
Range of A x B = {3,5,6}
