What is the slope of a line perpendicular to the line whose equation is
15x + 9y = 189. Fully reduce your answer.
Answers
We want to find the slope of a line perpendicular to 15*x + 9*y = 189.
The slope of the line perpendicular to the given line is 9/15.
First, a general line written in the slope-intercept form is written as:
y = a*x + b
Where a is the slope and b is the y-intercept.
And two lines are perpendicular if one has a slope that is equal to the inverse of the opposite of the other line's slope.
So, to find the slope of the line perpendicular to 15*x + 9*y = 189, first, we need to find the slope of this line.
To do it, we need to isolate y.
9y = -15x + 189
y = (-15/9)*x + 189/9
So the slope is -15/9
A perpendicular line to this must have a slope equal to the inverse of the opposite of this, so the slope of the perpendicular line is:
-(-9/15) = 9/15
The slope of the line perpendicular to the given line is 9/15.

Suppose the average yearly salary of an individual whose final degree is a master's is $45 thousand less than twice that of an individual whose final degree is a bachelor's. Combined, two people with each of these educational attainments earn $117 thousand. Find the average yearly salary of an individual with each of these final degrees.
Answers
Answer:
$58500Step-by-step explanation:
let the degree holder earn x
then a masters degree holder earns= (2x-45,000)
the comnined amount of the two degree holders= (2x-45,000)+x
2x-45000+x=117000
3x=117000+45000
3x=162000
x=162000/3
x=$54000
so bachelor'sdegree hold earns= $54000
a masters degree holder earns= (2(54000)-45,000)
a masters degree holder earns= (108000-45,000)
a masters degree holder earns=$63000
the average= (54000+63000)/2
the average= (117000)/2
the average=$58500
One car rental company charges $35 for the rental, plus $2 per mile driven. A second rental car company charges $20 for the rental, plus $5 per mile driven. At how many miles will the two companies cost the same?
Answers
Answer:
b
Step-by-step explanation:
For 5 miles will the two companies cost the same.
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division.
Given that;
One car rental company charges $35 for the rental, plus $2 per mile driven.
A second rental car company charges $20 for the rental, plus $5 per mile driven.
Now,
Let distance for the two companies cost the same is x miles.
Then, for first condition we can formulate;
Total cost for x miles = $35 + $2x
And, For the second condition;
Total cost for x miles = $20 + $5x
So, For distance of the two companies which has cost the same;
$35 + $2x = $20 + $5x
$35 - $20 = $5x - $2x
$15 = $3x
x = 5
Thus, For 5 miles will the two companies cost the same.

find the slope, m and y-intercept of the line y=4x
Answers
Answer:
The answer is m=4
Step-by-step explanation:
Although it may not look like it this equation is in slope-intercept form. The slope-intercept form of a linear equation is:
y = m x + b
Where m is the slope and b is the y-intercept value.
Therefore:
The slope is:
m = 4
The y -intercept is: b = 0 or ( 0 , 0 )
The slope of the line is 4 and the y-intercept is 0.
We are given that;
Line equation y=4x
Now,
The slope-intercept form of a linear equation is y = mx + b, where m is the slope and b is the y-intercept.
To find the slope and y-intercept of the line y = 4x, we can compare it with the slope-intercept form and identify the values of m and b.
In this case, m = 4 and b = 0.
So, the slope of the line is 4 and the y-intercept is 0.
This means that the line passes through the origin (0,0) and rises 4 units for every 1 unit it moves to the right.
Therefore, by slope answer will be 4 and 0.

Answer:
x = 3
Step-by-step explanation:
Since the 3 angles in the triangle are equal, then the triangle is equilateral.
Thus the 3 sides are congruent.
Equate any 2 of the sides and solve for x, that is
12x - 13 = 7x + 2 ( subtract 7x from both sides )
5x - 13 = 2 ( add 13 to both sides )
5x = 15 ( divide both sides by 5 )
x = 3

2.You would multiply 3*2 giving you six and then you would add the exponents together giving you 5 leaving 6p^5 as your final answer
3.When solving an equation like this you have to use The Product Rule meaning exponents with the same base number you would add the exponents which in this case results in 3+7=10 therefore leaving you with a^10
