First off need to plot the equation on the graph..
After doing this you determine that the slope of the line it is perpendicular to is 3/7 and it has a y-intercept of 36/7.
Slope intercept is y= mx+b
"m" being the slope and "b" being your y-intercept.
Well..
This isn't your final answer..
All you have to do is reverse the slope by making it negative to make it perpendicular to the line.
So..
Final Answer is: y= -3/7x+36/7 or y= -3/7x+5.142 (rounded to the nearest thousandth).
In the slope intercept form equation, y =mx+b, m is the slope, or the coefficient of x.
Therefore, the slope, or m, in this situation is -2/3.
Hope this helps!
Answer:
Mean = 52.6
Median = 50
Mode = 50
Range = 9
Step-by-step explanation:
How to find the mean
- The mean of a set of numbers is the sum divided by the number of terms.
- You add 59,50,54,50,50 then divide it by 5 because there are 5 numbers
How to find the median
- Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
How to find the mode
- The mode is the element that occurs most in the data set. In this case,
- 50 occurs 3 times.
How to find the range
- Subtract the minimum data value from the maximum data value to find the data range. In this case, the data range is 59
−
50
=
9

Answer:
Given: x²5x - 10 = 0
On comparing the given equation with ax² + bx + c = 0, we get: a = 1, b = -5 and c = -10
For ax²+bx+c = 0, we know that,
-b ± √b² - 4ac 2a X =
[Quadratic
formula]
5± √(-5)² - 4 × 1 × (-10) ... X = 5± √65 2
2 x 1
5 ± 8.06 2
5 +8.06 5-8.06 2 2
13.06 3.06 2 2
Hence, x = 6.53, or x = -1.53.
