Answer:
Doesn't exist
Step-by-step explanation:

Hence, the slope of line doesn't exist.
Answer:
Place compass point on the vertex of the angle (point B), Stretch the compass to any length that will stay ON the angle, Swing an arc so the pencil crosses both sides (rays) of the given angle, Place the compass point on one of these new intersection points on the sides of the angle.
Step-by-step explanation:
6.665 grams of the 13 grams remain after 8 hours.
<h3>How much of a 13 gram sample of iron-52 would remain after 8 hours?</h3>
The decay equation for the 13 grams of iron-52 is:

Where N is the amount of iron-52, and t is the time in years.
Where we used the fact that the half-life is exactly 8.3 hours.
Now, the amount that is left is given by N(8h), so we just need to replace the variable t by by 8 hours, so we get:

So 6.665 grams of the 13 grams remain after 8 hours.

Answer:
if there is 4 students then each student gets about 4 1/2 cups of sugar.
Step-by-step explanation:
3+4+5+6=18
18/4=4.5
Answer:
1 no
2 I don't know
3 no
4 yes
5 2.5 is the slope
6 -0.5
7 no slope
Step-by-step explanation:
1 no because the y overlaps
2 not sure
3 it over laps
4 it never overlaps
5 y=2.5x-3
6 y=-0.5x+1
7 no slope it's just x=-2
for the 5-7 you can type that into demos and get more info
y=mx+b
m is the slope and b is y intercept
