Answer:
C
Step-by-step explanation:
The formula to find the slope of a line is:
(y2 - y1) / (x2 - x1)
We can substitute the points (-4, 7) and (5, -8) to find the slope:
(-8 - 7) / (5 - (-4))
(-15) / (5 + 4)
(-15) / 9
This can be simplified to
- 5 / 3
which is option C
Answer:
x=43
Step-by-step explanation:
(22+21)=43
Answer:
Improper: 2 42/9 proper: 6 6/9
Step-by-step explanation:
2 7/9 x 2/3
find the common denominator which is 9 so now we have,
2 7/9 x 2/9
find the numerator which is,
2 7/9 x 6/9
multiply
2 42/9
This fraction is improper so lets make it proper,
42 goes into 9 four times
so we have,
6/9 + 2 + 4
final answer,
6 6/9
Answer:
a. 199,389
b. b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.
Step-by-step explanation:
a. Population in 2009 = 192,370
This means that in 2005 the population = 192,370 x 1.009 x 1.009 x 1.009 x 1.009 = 199,389
b. From the part A, the question suggests a 0.9% yearly decrease which amounts to 199,389. This answer does not correspond to their recorded figure because the 0.9% decrease was just an average taken over the period. There could be years that the decrease was way smaller than the recorded average, thus using average may not be a good way for calculating population decrease over a period of time.
M is also the midpoint of the diagonal BD.
In a parallelogram, the diagonals are perpendicular bisectors of each other. That means that midpoint of one of the diagonals is also the midpoint of the other diagonal.
