3(-y+2)+2y=12
-3y+6+2y=12
-y +6 = 12
-y = 6
y= -6
x = 6 + 2 = 8
(8, -6)
Answer:
quadrant 1 that the graph is mainly in
The area of the entire circle = pi r^2
The area of the shaded area = (40/360) * pi r^2
r = 9 cm
Area of the shaded area = 1/9 * 3.14 * 9^2
Area of the shaded area = 3.14 * 9
Area of the shaded area = 28.26
Notice one of the 9s disappeared. Where did it go?
You could begin the problem by writing out 9^2
Area = 1/9 * 3.14 * 9 * 9 Notice that 1/9 will cancel out 1 of the nines.
28.26 yds = Shaded area.
Answer:
Only the mean increased.
Step-by-step explanation:
The mean is the total divided by the number of scores, and since adding 21 will increase the total score significantly, the mean increases.
The median is still 7.
Answer:
(-4)(9), (6)(6)(-2), (6)(-6)
Explanation
Ok so when you multiply (-4)(9) you get (-36)
6×6 = 12 × (-2) = (-24)
And 6×(-6) = (-36)
The rest that I worked out all result in postitive numbers.
Hope this helps you!
