<u>Equation of a Line</u>
We can find the equation of a line by using two sets of data. It can be a pair of ordered pairs, or the slope and a point, or the slope and the y-intercept, or many other combinations of appropriate data.
We are given a line
And are required to find a line perpendicular to that line. Let's find the slope of the given line. Solving for y
The coefficient of the x is the slope
The slope of the perpendicular line is the negative reciprocal of m, thus
We know the second line passes through (2,3). That is enough information to find the second equation:
Operating
Simplifying
That is the equation in slope-intercept form. Intercept: y=4
The percentage that the number of airlines with an average airplane age of 14 is less than the number of airlines with an average airplane age of 11 is:
B. 20%.
<h3>What is a percentage?</h3>
The percentage of an amount a over a total amount b is given by a multiplied by 100% and divided by b, that is:
The percentage of airlines with an average age of 14 years is:
The percentage of airlines with an average age of 11 years is:
The difference is:
33.33% - 13.33% = 20%.
Hence option B is correct.

Answer:
3 units
Step-by-step explanation:
Hello
The sphere volume is:
(4/3)*Pi*r^3
then
36 = (4/3)*Pi*r^3
36/[(4/3)*Pi] = r^3
8,5 = r^3
r = 3

Answer:
(26, 
)
Step-by-step explanation:
Hi there!
We are given the coordinates (26, 56) and (26, 1)
We want to find the midpoint of these two points
The midpoint can be found using the formula 
, where 
& 
are points
We have 2 points, which is what we need to find the midpoint, but let's label the values of the points to avoid confusion and mistakes when actually calculating
Now substitute these values into the formula.
Add the numbers together
Divide
(26, )
Hope this helps!
