The solution of equations are one solution, infinitely many solutions, one solution and no solution.
We are given that;
The four equations
Now,
To determine whether an equation has no solution, one solution, or infinitely many solutions, we can try to solve for the variable and see what happens.
Let's apply this method to each equation:
a. 8p + 1 = 4p + 2
4p + 1 = 2
Subtracting 1 from both sides, we get:
4p = 1
p = 1/4
This is a consistent result, so the equation has one solution: p = 1/4.
b. -6p + 7 = 7 - 6p
Adding 6p to both sides, we get:
7 = 7
This is an identity, so the equation has infinitely many solutions. Any value of p will satisfy the equation.
c. p + 9 = 2p - 3
Subtracting p from both sides, we get:
9 = p - 3
Adding 3 to both sides, we get:
12 = p
This is a consistent result, so the equation has one solution: p = 12.
d. 5p + 3 = 5p - 1
Subtracting 5p from both sides, we get:
3 = -1
This is a contradiction, so the equation has no solution.
Therefore, by the equation answer will be one solution, infinitely many solutions, one solution and no solution.

A fit is rolled 25 times and 12 evens are observed. Calculate and interpret a 95% confidence interval to estimate the true proportion of evens rolled on a die.
Answer:
95% confidence interval to estimate the true proportion of evens rolled on a die.
(0.197368 , 0.762632)
Step-by-step explanation:
Explanation:-
Given A fit is rolled 25 times and 12 evens are observed
proportion [tex]p = \frac{x}{n} = \frac{12}{25} = 0.48[/tex]
q = 1 - p = 1- 0.48 = 0.52
Level of significance =0.05

Step-by-step explanation:
at basketball camp kylie made 18% of her free throws based on this information which is the best prediction of the number of free throws she will make out of 50 attempts
Answer:
Number of free throws = 9
Step-by-step explanation:
Given that:
Kylie made 18% of her free throws.
Number of attempts = 50
Based on the information, she will make out 18% free throws.
Number of free throws = 18% of 50
Number of free throws = [tex]\frac{18}{100}*50[/tex]
Number of free throws = 0.18 * 50
Number of free throws = 9
Hence,
Number of free throws = 9

Graph y = -3/2x - 3.
Answer:
Step-by-step explanation:
One point can be the y-intercept. We can see that the y-intercept is (0,-3). -3 is the value of y when x = 0. The next point can be when x = 2. If we plug that in the equation, we get the point (2,-6).
Plotting these two points will graph the equation.
The graph is given below.
Some of the coordinates on the graph are (0, -3, (1, -4.5), and (2, -6).
What are coordinates in a graph?The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.
The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.
We have,
y = (-3/2)x - 3
The coordinates from the given equation are:
When x = 0,
y = - 3
(0, -3)
When x = 1,
y = -3/2 - 3 = (-3 - 6)/2 = -9/2 = -4.5
(1, -4.5)
When x = 2,
y = -3 - 3 = -6
(2, -6)
Now,
The graph of the equation is given below.
Thus,
The graph is given below.

Write the equation of the line that passes through the points (-8,-1) and (5,-7). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line
Answer:
The answer to the question provided is:
[tex]y + 1 = - \frac{6}{13} (x + 8)[/tex]
Step-by-step explanation:
❃Incase you forgot what the point-slope formula is ☟

Line segment JK is divided by point L in the ratio of 3:2. Endpoint J is at (-16, 2) and point L is at (-15, -20). What are the coordinates of endpoint K?
9514 1404 393
Answer:
K(-14 1/3, -34 2/3)
Step-by-step explanation:
The division ratio says ...
(L -J)/(K -L) = 3/2
2(L -J) = 3(K -L)
5L -2J = 3K
K = (5L -2J)/3
K = (5(-15, -20) -2(-16, 2))/3 = (-75+32, -100-4)/3 = (-43/3, -104/3)
K = (-14 1/3, -34 2/3)

D. about 40 miles
Step-by-step explanation:
In order to answer the question, you first need to find how many units on the graph Seaside is from Oceanfront - or how long the line between the two points is.
To do this, use the distance formula, [tex]d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex].
[tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point, and [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point. Use the points of Seaside (by looking on the graph, you can see it's (-2,4)) and Oceanfront (also by looking, you can see it's (3, -2)) for the formula:
[tex]d = \sqrt{((-2)-(3))^2+((4)-(-2))^2\\[/tex]
[tex]d = \sqrt{(-2-3)^2+(4+2)^2}[/tex]
[tex]d = \sqrt{((-5)^2+(6)^2\\[/tex]
[tex]d = \sqrt{25 + 36} \\d = \sqrt{61}[/tex]
[tex]\sqrt{61}[/tex] units is about 7.8 units (you can also tell because it's in between [tex]\sqrt{49}[/tex] and [tex]\sqrt{64}[/tex], which equal 7 and 8). Multiply that by 5 (since each unit on the graph represents 5 miles) and the answer is about 40. So, the answer is D.
What is the equation of a line that is parallel to 2x +3y = 3 and passes through the point (3, -4) ?
Answer:
2x + 3y = -6
Step-by-step explanation:
The equation of the new line will be identical to that of the given line except that the constant term will differ.
Start with the given 2x + 3y = 3 and replace x with 3 and y with -4. We get:
2(3) + 3(-4) = C, and C = 6 - 12 = -6
The equation of the new line is therefore 2x + 3y = -6
Find x and y so the quadrilateral is a parallelogram.
Answer:
Summary:
The value of x = 7 The value of y = 4Step-by-step explanation:
We know that the diagonals of a parallelogram bisect each other.
As
The parallelogram PQRS is given, so
RT = TP
Given
RT = xTP = 5x-28plug in RT = x and TP = 5x-28 in the equation RT = TP
RT = TP
x = 5x-28
switch the sides
5x-28 = x
adding 28 in both sides
5x-28+28 = x+28
simplify
5x = x+28
subtract x from both sides
5x-x = x+28-x
4x = 28
divide boh sides by 4
4x ÷ 4 = 28 ÷ 4
simplify
x = 7
Therefore, we conclude that the value of x is: x = 7
Similarly,
QT = TS
Given
QT = 5yTS = 2y+12plug in QT = 5y and TS = 2y+12 in the equation QT = TS
QT = TS
5y = 2y+12
subtract 2y from both sides
5y - 2y = 2y+12-2y
simplify
3y = 12
divide both sides by 3
3y ÷ 3 = 12 ÷ 3
simplify
y = 4
Therefore, we conclude that the value of y is: y = 7
Summary:
The value of x = 7 The value of y = 4Which is 42.364 written with words?
