Two parallel lines are cut by a transversal as shown below.
Suppose
Answer:
m < 2 = 36
m < 3 = 148
Step-by-step explanation:
180 - 148 = 32
The measure of <2=32 and <3=148
What is are parallel lines?Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect.
Given:
m<5 = 148
As, by alternate interior angle
m<5 = m<3
So, m<3 = 148
Also, <2 and <3 forms a linear pair.
So,
m<2 + M<3 = 180
148 + m<2 = 180
m<2 = 32
Hence, the measure of <2 = 32 and <3 = 148.

LCM : least common factorProfit is revenue minus expenses. If your profit is $3,000 and your revenue is $50,000, what are your expenses?
a) $45,000
b) $46,000
c) $47,000
d) $48,000
The expenses with the given profit and revenue is $47,000. Therefore, option C is the correct answer.
Given that, the profit is $3,000 and the revenue is $50,000.
What is gain or profit?The profit or gain is equal to the selling price minus the cost price. Loss is equal to the cost price minus the selling price.
Here, Profit = Revenue - Expenses
3000 = 50000 - Expenses
⇒ Expenses = 50000-3000
= 47000
The expenses with the given profit and revenue is $47,000. Therefore, option C is the correct answer.

Shaniqua brings home $250 per week working 25 hours. She is able to save $30 of her earnings each week.
Shaniqua wants to have $750 saved at the end of 15 weeks. She is allowed to work up to 30 hours per week if she
wants. She can save all the money earned working extra hours. How many hours (as a whole number) each week
must Shaniqua work to save $750 at the end of 15 weeks? Show your work.
Answer: She'd have to work 27 hours a Week because by her working 2 more hours shed be able to save up 50 a week.
Explanation: 750 divided by 15 (the weeks) is 50. Shed need to save 50 a week instead of 30 to reach her goal and the amount 50 divided by the number of hours she works (25) is 2. Add the 2 to 25 and you get 27 weeks.
Find the slope of the line $5x + 2y + 9 = 0$.
The slope of the line is -5/2
Slope m = -5/2
What is an Equation of a line?
The equation of a line is expressed as y = mx + b where m is the slope and b is the y-intercept
And y - y₁ = m ( x - x₁ )
y = y-coordinate of second point
y₁ = y-coordinate of point one
m = slope
x = x-coordinate of second point
x₁ = x-coordinate of point one
The slope m = ( y₂ - y₁ ) / ( x₂ - x₁ )
Given data ,
Let the equation of the line be A
Now , the equation of line is expressed as
5x + 2y + 9 = 0
Now , the equation of line is expressed in the form y = mx + c
5x + 2y + 9 = 0
Subtracting 9 on both sides of the equation , we get
5x + 2y = -9
Subtracting 5x on both sides of the equation , we get
2y = -5x - 9
Divide by 2 on both sides of the equation , we get
y = ( -5/2 )x - 9/2
So , the slope of the equation is y = mx + c
The slope of the line is m
The slope is m = -5/2
Hence , The slope of the line is -5/2

General Formulas and Concepts:
Order of Operations: BPEMDASExpand by FOIL (First Outside Inside Last)Step-by-step explanation:
Step 1: Define
f(x) = x² - 3x - 2
f(x + 3) is x = x + 3
Step 2: Find
Substitute: f(x + 3) = (x + 3)² - 3(x + 3) - 2Expand by FOILing: f(x + 3) = x² + 6x + 9 - 3(x + 3) - 2Distribute 3: f(x + 3) = x² + 6x + 9 - 3x - 9 - 2Combine like terms: f(x + 3) = x² + 3x - 2the number of successes and the sample size are given for a simple random sample from a population. determine the sample proportion for x
Complete Question
The number of successes and the sample size for a simple random sample from a population are given below. x-4, n 200, [tex]H_o[/tex]: p- 0.01, Ha p>0.01, a 0.05 . determine the sample proportion of x
Answer:
The sample proportion of x is [tex]\^ p = 0.02[/tex]
Step-by-step explanation:
From the question we are told that
The number of success is x = 4
The sample size is n = 200
The null hypothesis is [tex]H_o : p = 0.01[/tex]
The alternative hypothesis is [tex]H_a : p > 0.01[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
Generally the sample proportion of x is mathematically represented as
[tex]\^ p = \frac{x}{n}[/tex]
=> [tex]\^ p = \frac{4}{200}[/tex]
=> [tex]\^ p = 0.02[/tex]

Graph the equation y=-x^2+12x-32y on the accompanying set of axes. You must plot 5 points including the roots and the vertex.
The vertex of the quadratic function y = - x² + 12 · x - 32 is located at point (0, - 20) and the roots of the abovementioned are points (4, 0) and (8, 0), respectively.
How to graph a quadratic function
By fundamental algebra theorem we need at least three no coplanar different points to graph quadratic functions. First, we determine 5 different points, then we pass the curve through the five points and finally we identify the roots and the vertex.
If we know that (- 16, - 480), (- 12, - 320), (- 8, - 192), (- 4, - 96), (0, - 32), then the graph of the quadratic function is shown in the image.
The vertex of the quadratic function y = - x² + 12 · x - 32 is located at point (0, - 20) and the roots of the abovementioned are points (4, 0) and (8, 0), respectively.
