The exam started at 11:20 AM after 1hour and 20 minutes billy finished and left the room he left 15 minutes before me At what time did i leave the exam room

12:55 PM

Step-by-step explanation:

11:20AM + 1 Hour = 12:20PM

12:20PM + 20 Mins. = 12:40PM

12:40PM + 15 Mins. = 12:55PM

12:55.

Step-by-step explanation:

11:20 + 1 hour 20 minutes = 12:40

Plus the 15 minutes that you stayed behind.

12:40 + 15 = 12:55.

this shows a reflection over the x-axis and is translated one unit down and 6 units to the right (x + 6, y - 1)

hope this !

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
