Question 9 of 25
Give the slope of y-3= 4(x+8) and a point on the line.
OA. The slope is 3 and (-8, 4) is on the line.
B. The slope is 8 and (3, 4) is on the line.
OC. The slope is 4 and (-8, 3) is on the line.
OD. The slope is 4 and (8, -3) is on the line.
SUI
The slope of the line y-3= 4(x+8) is 4 and (-8, 30 is a point on line y - 3 = 4(x + 8).
According to the given question.
We have a equation of a line y-3= 4(x+8).
Here, we have to find the slope of a line y-3= 4(x+8) and a point on the line.
Since we know that, the equation of a lines through a point (x1, y1) is given by y - y1 = m(x - x1), where m is the slope of the line.
And the equation of slope intercept form for a line is y = mx + c.
So, compare the given equation of line y-3= 4(x+8) with the standard equation of line y - y1 = m(x - x1) which passes through the point (x1, y1), we get
point ( -8, 3) on line y-3= 4(x+8).
Now, the slope intercept form of the line y-3= 4(x+8) is
y - 3 = 4x + 32
⇒ y = 4x + 32 + 3
⇒ y = 4x + 35
Thereofore, the slope of the line y-3= 4(x+8) is 4.
Hence, the slope of the line y-3= 4(x+8) is 4 and (-8, 30 is a point on line y - 3 = 4(x + 8).

Complex fraction 4²/₃ + 1/3 – 4¹/₃ = 2/3
A fraction defined as the part of the whole thing. For example, a pizza is divided into four equal pieces, then each piece is represented by ¼. Fractions help to distribute and judge the numbers easily and make the calculation faster.
Some steps to solve a fraction -
Step 1: Write the factors of numerator and denominator.
Step 2: Determine the highest common factor of numerator and denominator.
Step 3: Divide the numerator and denominator by their highest common factor (HCF). The fraction so obtained is in the simplest form.
For example -
4²/₃ + 1/3 – 4¹/₃
= (4 × 3 + 2)/3 + 1/3 – (4× 3 + 1)/3
= 14/3 + 1/3 – 13/3
= (14 + 1 - 13)/3
= (15 - 13)/3
= 2/3

HOW MUCH TICKETS DID THE MOVIE SELL?
Movie a costs 4 dollars
Movie b costs 5 dollars
Movie theater got 200 dollars and sold 47 tickets
How many tickets did movie a sell
PLS ANSWER ILL GIVE BRAINLIEST
Taking into account the definition of a system of linear equations, the movie theater sold 35 tickets for Movie A and 12 tickets for Movie B.
System of linear equationsA system of linear equations is a set of two or more equations of the first degree, in which two or more unknowns are related.
Solving a system of equations consists of finding the value of each unknown so that all the equations of the system are satisfied. That is to say, the values of the unknowns must be sought, with which when replacing, they must give the solution proposed in both equations.
Number of tickets soldIn this case, a system of linear equations must be proposed taking into account that:
xa: number of tickets sold for Movie Axb: number of tickets sold for Movie BOn the other hand, you know:
Movie A costs 4 dollars.Movie B costs 5 dollars.Movie theater got 200 dollars.Movie theater sold 47 tickets.So, the system of equations to be solved is
[tex]\left \{ {{xa + xb=47} \atop {4xa + 5xb=200}} \right.[/tex]
There are several methods to solve a system of equations, it is decided to solve it using the substitution method, which consists of clearing one of the two variables in one of the equations of the system and substituting its value in the other equation.
In this case, isolating the variable xa from the first equation, you obtain:
xa= 47 - xb
Substituting this expression in the second equation you get:
4×(47 -xb) + 5xb= 200
Solving:
4×47 - 4xb + 5xb= 200
188 - 4xb + 5xb= 200
- 4xb + 5xb= 200 - 188
xb= 12
Remembering that xa= 47 - xb. you get: xa=47 - 12 → xa= 35
Finally, the movie theater sold 35 tickets for Movie A and 12 tickets for Movie B.

Based on the records for the past several seasons, a sports fan believes the probability the red team wins is 0.35. The fan also believes the probability the blue team wins is 0.40. In a season with 160 games, how many fewer games should the fan expect the red team to win?
If a sports fan believes that, the probability of the red team winning is 0.35 and that of the blue team winning is 0.40, then the fan expects the red team to win 9 matches less than the blue team in a season of 180 games.
As per the question statement, based on the records for the past several seasons, a sports fan believes that, the probability of the red team winning is 0.35 and that of the blue team winning is 0.40.
We are required to calculate the number of games, the fan expects the red team to win, lesser than the blue team in a season of 180 games.
As per the probability record, maximum number of games, the fan believes that the blue team can win all over the season of 180 games = [tex](0.40*180)=(\frac{40}{100}*180)=(4*18)=72.\\[/tex]
Similarly, maximum number of games, the fan believes that the red team can win all over the season of 180 games = [tex](0.35*180)=(\frac{35}{100}*180)=(7*9)=63.\\[/tex]
Hence, the fan expects the red team to win [tex][(72-63)=9][/tex] matches less than the blue team in a season of 180 games.

In a random sample of 144 observations, begin mathsize 15px style p with bar on top end style = .7. The 95% confidence interval for p is
The 95% confidence interval for p is (0.333, 0.480).
What is the confidence interval?If the sample size is given to be n < 30, then for finding the confidence interval for mean of population from this small sample, we use t-statistic.
The formula for calculating the confidence interval is expressed as shown below;
CI = p±Z * √p(1-p)/n±0.5/n
Where Z is the z-score at 95% confidence
p is the sample proportion
n is the sample size
Given that n = 144, p = 0.7 and z-score at 95%
CI = 1.645 (from z table)
Now Substituting this values;
CI = p ± 1.645*√0.7(1-0.4)/144 ±0.5/n
CI = 0.4 ± 1.645*√0.7(0.6)/144 ± 0.5/144
CI = 0.4 ±1.645 * √0.24/144 ± 0.00347
CI = 0.4 ±1.645 * 0.04087± 0.00347
CI = 0.4±0.06723±0.00347
CI =(0.333, 0.480)
Hence, The 95% confidence interval for p is (0.333, 0.480).

b) b) Use Descarters' Rule of Signs, we know that there are ____ negative real zeros P can have.
Using Descartes's Rule of Signs:
There are four positive real zeros P can have.
There are zero negative real zeros P can have.
What is Descartes's rule of sign?Descartes' rule of sign is used to determine the number of positive and negative real zeros of a polynomial function.
We have,
P(x) = 2[tex]x^{4}[/tex] - 7x³ + x² - 18x + 3

There are 4 variations so there are 4 positive real zeroes.
For finding negative real zeroes we Put x = -x.
P(-x) = 2[tex]x^{4}[/tex] + 7x³ + x² + 18x + 3
2[tex]x^{4}[/tex] + 7x³ + x² + 18x + 3

Compare the steepness of the following functions. How does F3 compare to F1
Answer:
Function 3 is less steep.
Step-by-step explanation:
The steepness of a linear function is determined by its coefficient of x.
Since the coefficient of x in [tex]f_3(x)[/tex], 0.5, is smaller than that of [tex]f_1(x)[/tex], 2, function 3 is less steep than function 1.
Significance of the coefficient of x
We can think of the function as an equation of a line in the slope-intercept form. That is, y= mx +c, where m is the slope and c is the y-intercept.
Steepness and value of x
The larger the numerical value of m, the steeper the line is.
Significance of the sign of x
The sign (positive or negative) of m tells us the direction in which the line is sloping towards. A positive m value gives us a line sloping upwards from left to right, while a negative m value gives us a line that is sloping downwards from left to right.

Step-by-step explanation:
assuming I = E(R + r), prove that I/I = R/E + r/E
If we assume that I = E(R + r), then I/I = R/E + r/E.
The inverse of a value of a number is known as the reciprocal of the number. The reciprocal can be found out by replacing the numerator with the denominator and vice versa. For example, reciprocal of a number x will be 1/x and vice versa.
Here, we are given that I = E/(R + r)
Taking reciprocals of both sides we get-
Reciprocal of I will be- 1/I
Reciprocal of E/(R + r) will be- (R + r)/ E
Thus,
1/I = (R + r)/ E
Simplifying the equation further, we get-
1/I = R/E + r/E
