Question 3. Find the distance between P(4,5) and the line with equation 8x + 5y = 20
Answer:
Step-by-step explanation:
8x+5y = 20
y = (-8/5)x + 4
slope of the line is -8/5.
slope of any perpendicular to the line is ⅝.
line of slope ⅝ that passes through P(4,5):
y-5 = ⅝(x-4)
y = ⅝x + 2.5
find intersection of lines
⅝x + 2.5 = (-8/5)x + 4
25x + 100 = -64x + 160
89x = 60
x = 60/89, y = 260/89
distance between (60/89, 260/89) and (4,5) = 3.92

which correctly explains the number of solutions of the following system of linear equations? -3x + 3y = 12 y = x + 4
A. The Graphs of the equations are parallel lines because they have the same slope but different y-intercepts. The system has no solution
B. The graphs of the equations are lines that intersect at one point because the equations have the same slope but different y-intercepts. The system has exactly one solution
C. The graphs of the equations are lines that intersect at one point because the equations have the same slope and same y-intercept. The system has exactly one solution.
D. The graphs of the equations are the same line because the equations have the same slope and same y-intercept. The system has exactly Infinitely many solutions.
Please explain how you got the answer because I need to learn it.
The system has an infinite number of solutions because the equations have the same slope and y-intercept, and the graph of the equations is the same line.
What is an equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
The system of equations is given in the question, as follows:
-3x + 3y = 12
y = x + 4
When all the given equations are drawn in the graph, then we get the Infinitely many solutions ordered pairs in the solution set of the given system.
Here, the graph of the equations is the same line because the equations have the same slope and the same y-intercept. The system has exactly Infinitely many solutions.
Therefore, the correct answer would be an option (D).

what is the value of X. 2.5(x+4)= 4.75
Answer:
-2.1
Step-by-step explanation:
2.5(x+4)=4.75
or,2.5x+10=4.75
or,2.5x=4.75-10
or,2.5x= -5.25
or,x =-5.25/2.5
or,x= -2.1
∴x=-2.1
(Ans)
Hope you find it helpful.........
Answer:
2.5(x+4)=4.75
2.5x+10=4.75
2.5x=4.75-10
2.5x=-5.25
Divide through by 2.5
2.5x÷2.5=-5.25÷2.5
X=-2.1
Lucia measured the high school and made a scale drawing. The scale she used was 2 centimeters : 3 meters. The parking lot is 54 meters wide in real life. How wide is the parking lot in the drawing?
Answer: The parking lot in the drawing is 36 centimeters.
Step-by-step explanation:
Given: Actual width of parking lot = 54 meters
The scale she used was 2 centimeters : 3 meters.
i.e. 3 actual meters = 2 centimeters on drawing
⇒ 1 actual meter = [tex]\dfrac23[/tex] centimeters on drawing
⇒ 54 actual meters = [tex]54\times\dfrac23[/tex] centimeters on drawing
⇒ 54 actual meters = 36 centimeters
Hence, the parking lot in the drawing is 36 centimeters.

Answer:
53%
Step-by-step explanation:
add the males and females. then divide the males by the sum(290). and that's r answer.
Answer:
53%
Step-by-step explanation:
The easiest way to start this is to add the two values together to find the total amount of participants.
154+136=292
To find the percentage of males in the population, we need to divide the amount of men by the total population.
154/292=0.527397
The percentage of men is 53%.

Stephen purchased a guitar, which was originally priced at $80 but discounted at 25%. He also had to pay 5% sales tax. What amount did Stephen pay to purchase the guitar?
Discounted by 25% means he paid 75% of the original price:
80 x 0.75 = $60
Now multiply the sale price by 1 + tax rate:
60 x 1.05 = 63
He paid $63 total.
If the national average for a gallon of gas is $3.10, how much should you expect to pay for gas in philadelphia versus atlanta
Answer: $3.63 / $3.29
Step-by-step explanation:
In Philadelphia, you would pay:
= 3.10 * Percentage of national average for transport
= 3.10 * 117%
= $3.63
In Atlanta:
= 3.10 * Percentage of national average for transport
= 3.10 * 106%
= $3.29

Part B: Suppose Steven combined the table-
tennis balls into one large bag instead of two
individual bags. Would the probability change
from Part A if Steven wanted to draw a "1" and a
"B" without replacement?
A
Answer:
D.
Yes, the probability would change because you are drawing from one bag and this changes the number of possible outcomes.
Step-by-step explanation:
Yes, the probability would change because you are drawing from one bag and this changes the number of possible outcomes.
What is the probability?Probability in mathematics is the possibility of an event in time. In simple words how many times does that incident is happening in any given time interval?
Given:
Suppose Steven combined the table tennis balls into one large bag instead of two individual bags.
When the two bags are combined into one, the number of possible outcomes is reduced.
Drawing from one bag means that there is now only one set of balls to choose from, rather than two separate sets.
This means that the total number of possible outcomes is reduced, which changes the probability of drawing a "1" and a "B" without replacement.
Therefore, the probability would change.
