Solution:
we have been asked to find
Which equation represents the graphed function?
As we can see in the graph, the line is passing through the point (2,0) and (0,-3).
As we know the equation of the passing through two points is given by the formula
So the equation of the line will be
The line passes through (2,-3) and (4,2).
Calculate the slope of the line.
m = (2+3)/(4-2) = 5/2
The equation of the line is therefore
Cross multiply.
2(y-2) = 5(x-4)
2y - 4 = 5x - 20
2y = 5x - 16
Rewrite as
5x - 2y = 16
Answer: C. 5x - 2y = 16
Answer:
5
Step-by-step explanation:
The interquartile range is the difference between the upper quartile and the lower quartile.
First find the median.
The median is the middle value of the data set arranged in ascending order
1 5 5 7 9 ← data in ascending order
↑ median
The lower quartile is the middle value of the data to the left of the median. If there is not an exact middle then it the average of the values on either side of the middle.
1 5
↑ lower quartile = = 3
The upper quartile is the middle value of the data to the right of the median.
7 9
↑ upper quartile = = 8
Thus
interquartile range = 8 - 3 = 5
Step-by-step explanation:
-24=4+4w
-24-4=4w
-28=4w
4w÷4=-28÷4
w=-7
The equation of a parabola is:
If a>0, then the parabola opens up;
If a<0, then the parabola opens down.
