LCM - means least common multiple
The answer for this question is B
Answer:
Question 6. M(5, 2)
Question 7. M(-6, 0)
Step-by-step explanation:
1. C(3, -5) and D(7, 9)
Use the midpoint formula:
(x1 + x2/2, y1 + y2/2)
(3 + 7/2, -5 + 9/2)
(10/2, 4/2)
(5, 2)
2. S(-8, -6) and T(-4, 6)
Use the midpoint formula:
(x1 + x2/2, y1 + y2/2)
(-8 + -4/2, -6 + 6/2)
(-12/2, 0/2)
(-6, 0)
Sum of interior angle of polygon: S = (n-2) * 180°,
where n is number of sides and where S is total degrees.
With 6 sides, n = (6-2)*180 = 720°
Then set all of the interior equations equal to the sum, or
720 = 5x + 4x+2 + 5x+6 + 2x-2 + 3x+5 + x-10
720 = 20x + 1
719 = 20x
x =
= 35.95
Answer:
70
Step-by-step explanation:
It gives you two data points, (5, 350) and (6.5, 455). Constant rate of change also means slope, and the formula for slope is (y(1)-y(2))/(x(1)-x(2)). If you plug in the data points you got for this, you get (350-455)/(6.5-5), which is equal to 105/1.5. Drop that in a calculator and you get 70.
