What is the equation of the line, in point-slope form, that passes through the points (9, 1) and (4, 16)?
A. y + 1 = -3(x + 9)
B. y - 1 = -3(x - 9)
C. y + 1 = 3(x + 26)
D. y - 1 = 3(x - 26)
Answer:
B. y - 1 = -3(x - 9)Step-by-step explanation:
The point-slope form of an equation of a line:
[tex]y-y_1=m(x-x_1)[/tex]
m - slope
(x₁, y₁) - point
The formula of a slope:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
We have the points (9, 1) and (4, 16). Substitute:
[tex]m=\dfrac{16-1}{4-9}=\dfrac{15}{-5}=-3[/tex]
[tex]y-1=-3(x-9)[/tex]
The equation of the line that passes through the points (9, 1) and (4, 16) in point-slope form is y - 1 = -3(x - 9).
Explanation:To find the equation of a line, we can use the point-slope form, which is y - y₁ = m(x - x₁), where (x₁, y₁) is a point on the line and m is the slope of the line.
Given the points (9, 1) and (4, 16), we can calculate the slope using the formula m = (y₂ - y₁) / (x₂ - x₁).
Substituting the values, we get m = (16 - 1) / (4 - 9) = -3. So, the equation of the line in point-slope form is y - 1 = -3(x - 9).

if you place these marbles in a bag, close your eyes, and choose a marble, what is the probability that it will be
Answer:
P(blue) = 3/7
So '7' belongs in the box
Step-by-step explanation:
There are 14 total marbles, 6 of which are blue. The probability of pulling a blue marble out of the bag is
P(blue) = 6/14, which reduces to 3/7
The probability of drawing a particular marble from a bag depends on the number of that marble initially in the bag and whether the marbles are replaced after being drawn. Probabilities are calculated based on these conditions, including removing a marble of a particular color after another specific color has been removed.
Explanation:The subject of the question is probability, a concept in mathematics. The possibility of drawing a particular color of marble from a bag depends on how many of that color is in the bag to start with, as well as whether or not the marbles are replaced after being drawn.
In the case of James and his bag of four blue and three white marbles, the probability of drawing a blue marble is 4 out of 7 the first and second time he draws because the blue marble is replaced each time.
On the other hand, if the first drawn marble is not replaced (like in the second example), the total number of marbles, and thus the probabilities, change. For instance, after drawing and setting aside one blue marble from a bag containing four blue and three white marbles, the probability of drawing another blue marble becomes 3 out of 6, or 1/2.
Finally, in the case of Mark and his bag of green, red, and yellow marbles, the probability of drawing a yellow marble and then a green marble without replacement can be calculated as the product of the possibility of attracting a yellow marble first, and then the conditional probability of drawing a green marble given that a yellow one has already been removed. This shows how probabilistic events can be dependent on one another.

What is the mean absolute deviation
3,5,8,1,4
Answer:
the mean is 4.2
Step-by-step explanation:
Answer:
Mean absolute deviation: 1.84.
Step-by-step explanation:
How do you find the mean absolute deviation for a bunch of numbers?
Calculate the average (a.k.a. mean) of the numbers.Calculate the absolute difference (just discard any negative "-" sign in front of the difference) between each number and the mean. The mean absolute deviation is the average of all those absolute differences.What's the mean of those numbers?
(3 + 5 + 8 + 1 + 4) / 5 = 4.2.
Absolute difference:
3 - 4.2 = -1.2. Drop the negative sign to get 1.2.5 - 4.2 = 0.8.8 - 4.2 = 3.8.1 - 4.2 = -3.2. Drop the negative sign to get 3.2.4 - 4.2 = - 0.2. Drop the negative sign to get 0.2.What's the average of those absolute differences?
(1.2 + 0.8 + 3.8 + 3.2 + 0.2) / 5 = 1.84. That's the mean absolute deviation of those five numbers.

What is a numerical expression?A numerical expression is a mathematical statement written in the form of numbers and unknown variables. We can form numerical expressions from statements.
Given, If they don't gain at least ten yards, the other team gets the ball.
Therefore, the sequences of four plays that result in the team getting to keep the ball should be more than 10 yards when we take the sum of the sequences.
So, 8 - 3 + 4 + 21 = 30 yards.
30 - 7 - 8 - 12 = 3 yards.
2 + 16 - 5 - 3 = 10 yards.

Choose an equation that when paired with the equation below, will create a system of equations with infinitely many solutions, one solution, or no solutions.
Answer:
Infinitely many solutions: [tex]-5x+9y=2[/tex]
One solution: [tex]-10x+5y=4[/tex]
No solution: [tex]-10x+18y=5[/tex]
Step-by-step explanation:
Solve for y from each equation to obtain the equation of the line in slope-intercept form:
[tex]y=mx+b[/tex]
m: slope
b: y-intercept
EQUATION ON THE TOP:
[tex]-10x+18y=4\\\\y=\frac{5}{9}x+\frac{2}{9}[/tex]
Equation 1:
[tex]5y=10x+4\\\\y=2x+\frac{4}{5}[/tex]
The equation on top and the equation equation 1 has different slopes and different y-intercept, therefore the system will have one solution.
Equation 2:
[tex]9y=5x+2\\\\y=\frac{5}{9}x+\frac{2}{9}[/tex]
The equation on top and the equation equation 2 are the same, therefore, the system will have infinitely many solutions.
Equation 3:
[tex]18y=10x+5\\\\y=\frac{5}{9}x+\frac{5}{18}[/tex]
The slopes are equal, then both lines will be parallels, therefpre the system will have no solution.
To form a system with infinite, one or no solutions, a second equation is chosen to be identical or a multiple, have different coefficients, or the same slope but different constants relative to the first equation, respectively.
Explanation:To address the student's question about creating a system of equations with either infinitely many solutions, one solution, or no solutions, it is important to understand the properties of linear equations. When two equations are combined to form a system, the number of solutions is determined by their graphs on a coordinate plane. Three scenarios are possible:
Infinitely many solutions: This occurs when the two equations represent the same line; thus, they are identical or multiples of each other.One solution: This happens when the two lines intersect at a single point, meaning that they are not parallel and have different slopes.No solutions: This is the case when the two lines are parallel but not coincident, having the same slope but different y-intercepts.To create a system with a known outcome, one must write a second equation with either the same coefficients and constant term (for infinitely many solutions), different coefficients (for one solution), or the same coefficients but a different constant term (for no solutions).
For example, if the given equation is y = 2x + 3, an equation for infinitely many solutions could be 2y = 4x + 6, for one solution y = -x + 1, and for no solutions y = 2x + 5.

8x+5=bx-7 In the equation shown above, b is a constant. For what value of b does the equation have no solutions?
A: -8
B: -7
C: 5
D: 8
Answer:
D: 8
Step-by-step explanation:
8x+5=bx-7
Subtract bx from each side
8x-bx+5=bx-bx-7
8x-bx +5 = 7
Subtract 5 from each side
8x-bx +5-5 = 7-5
8x-bx =2
Factor out the x
(8-b)x =2
When 8-b =0 we have
0=2 which means we have no solutions since this is never true
8-b=0
Add b to each side
8-b+b=0+b
8=b
Final answer:
For the equation 8x + 5 = bx - 7 to have no solution, the value of b must be d. 8, which results in parallel lines if graphed and signifies an inconsistent equation.
Explanation:
The student has presented the equation 8x + 5 = bx - 7. To find for what value of b the equation has no solutions, we need to compare the coefficients on both sides of the equation because the variables must match for the equation to have a solution. When the coefficients of 'x' are equal, but the constants are different, the equation has no solution. In other words, the equation will be inconsistent, resulting in parallel lines if graphed.
Likewise, if b equals 8, the equation becomes 8x + 5 = 8x - 7. Subtracting 8x from both sides results in an equation 5 = -7, which is a contradiction and hence the equation has no solution. This means the correct answer is Choice D: 8.
