Answer:
y - 10 = 2(x - 4)
Step-by-step explanation:
Recall this: The slope of a new line perpendicular to a given line is the negative reciprocal of the slope of the given line.
Thus: The slope of the new line is the negative reciprocal of (-1/2), or +2.
Using the point-slope formula for the equation of a line,
y - k = m(x - h)
becomes
y - 10 = 2(x - 4)
This could also be written as y = 2x - 8 + 10, or y = 2x + 2
To find the mean is to find the average, which means add all the data values together and divide by the number of data values. In this case, we add those values together and divide by 6, which equals 82.5/6= 13.75
Answer:
D.30,40,50
Step-by-step explanation:
A.4,5,6
B.2,3,4
C.10,20,30
D.30,40,50
The Pythagoras theorem : a² + b² = c²
where a = length
b = base
c = hypotenuse
4² + 5² = 25 is not equal to the square of 6 which is 36
2² + 3² = 10 . 10 is not equal to the square of 4 which is 16
10² + 20³ = 500. 500 is not equal to the square of 30 which is 900
30² + 40² = 2500. this is equal to the square of 50
The number 4.2 from the set will make the equation x+2=6.2 true.
