Answer:

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).

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).

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.

Answer:

A 8+9+(-3)+4+21 is positive

C  2+16+9-5)+(-3) is also positive

Step-by-step explanation:

The sequence of four plays that the team keeps the ball is,

A. 8, -3, 4, 21.

C. 2, 16, -5, -3.

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.

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.

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.

Step-by-step explanation:

The length of the arc AB is equal to the circumference times the fraction of the circle

AB = 2*pi*r * (degrees/360)

AB = 2 * pi* (27) * (20/360)

    = 54 * pi * (1/18)

    = 3 pi

We are asked to leave the answer in terms of pi

Actually, the answer should be 1/9 π. To convert from degrees to radians, you use the conversion π/180°. This is what you do: 20°/1 times π/180°. This let's you cancel out the degrees so you are left in terms of pi. That gets you 20π/180 which simplifies to 1/9 π or 0.11π if you need it as a rounded decimal.

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.

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:

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.

Answer:  The required median of the given data set is 16.5.

Step-by-step explanation:  We are given to find the median of the following set of values :

11,  13,  14,  15,  18,  20,  23,  26.

We know that

(i) If the data contain an odd number of values, then the mid-value is the required median.

(ii) If the data contain an even number number of values, then the average of the two mid-values will be the required median.

Since the given data contains 8 values, which is an even number, so we will consider two mid-values and those are 15 and 18.

The average of 15 and 18 is given by

[tex]A=\dfrac{15+18}{2}=\dfrac{33}{2}=16.5.[/tex]

Thus, the required median of the given data set is 16.5.

Answer:

x = 6, y = -1.

Step-by-step explanation:

7x = 3y + 45

4x + 5y = 19.... (1)  

Rearranging the first equation:

7x - 3y = 45-----(2)

Multiply equation (1) by  3 and equation (2) by 5:

12x + 15y = 57

35x - 15y =  225

Adding :

47x  + 0 = 282

x = 282 / 47 = 6.

To find the value of y  substitute x = 6 into equation (2):

7(6) -3y = 45

-3y = 45 - 42 = 3

y = 3/-3 = -1.

Answer:

x = 6 and y = -1

Step-by-step explanation:

It is given two equations,

7x = 3y + 45

⇒ 7x - 3y = 45    -------(1)

4x + 5y=19

⇒  4x + 5y = 19    --------(2)

To solve these equations

eq (1) * 4  ⇒   28x - 12y =180  ----(3)

eq (2) * 7 ⇒    28x + 35y = 133   ----(4)

eq(3) - eq(4) ⇒   0x - 47y = 47

y = -47/47 = -1

eq(1) ⇒ = 7x - 3*-1 = 45

7x + 3 = 45

7x = 45 - 3 = 42

x = 42/7 = 6

Therefore x = 6 and y = -1

the coefficient is the number before x

in this case the coefficient is -1.

The formula to find the radius of a circle, given the area, is r = √(A/π). This comes from rearranging the formula for the area of a circle, A = πr², to solve for r.

The area of a circle (A) is traditionally calculated with the formula A = πr², where A represents the circle's area, and r represents the circle's radius. If we want to rewrite this formula to solve for the circle's radius (r), we would divide both sides of the equation by π and then take the square root. This gives us the formula r = √(A/π). So, if we know the area of the circle and want to find out its radius, we can use this formula.
