Which linear inequality is represented by the graph
Option B is correct, y≤1/3x-4 is the linear inequality which is represented by the graph
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
The equation of line passing through points (3, -3) and (0, -4)
Slope = -4+3/0-3
=1/3
Now let us find y intercept
-4=1/3(0)+b
b=-4
Equation is y=1/3x-4
y≤1/3x-4 is the required inequality of the graph
Hence, y≤1/3x-4 is the linear inequality which is represented by the graph

w is partly constant and partly varies inversely as the square of t. when w=24, t=4 and when w=18, t=2.
i. determine the law connecting w and t
ii. find t when w = 46
To find the law connecting w and t, we establish w as partly constant and partly inverse to t squared. Using given values, we find constants k and c and then solve for t when w is 46.
The problem states that w is partly constant and partly varies inversely as the square of t. Given two sets of values for w and t, we can establish the relationship between them. Since the variation is inverse with respect to the square of t, we can write the relationship as:
w = k / t2 + c
where k is a constant of variation and c is the constant part of w. To find these constants, we use the given data points (24, 4) and (18, 2). Substituting these into the equation, we get two simultaneous equations:
24 = k / 42 + c18 = k / 22 + cSolving these will give us the values of k and c, which then allows us to find t when w = 46.
To solve for t when w = 46, we plug this value into our established equation and solve for t. We'll end up with a quadratic equation in terms of t that we need to solve to find the time t.

What is the surface to a rectangular playing surface with 44 feet and 77 feet?
log(w^2+21)=log(10w)
[tex]\[ w = 7 \][/tex]
Explanation:The given equation is [tex]\(\log(w^2+21)=\log(10w)\)[/tex]. To find the solution, we can set the arguments of the logarithms equal to each other, giving [tex]\(w^2 + 21 = 10w\)[/tex].
Rearranging, we get a quadratic equation [tex]\(w^2 - 10w + 21 = 0\).[/tex] Factoring or using the quadratic formula yields the solutions
However, we need to check for extraneous solutions. Substituting [tex]\(w = 3\)[/tex] back into the original equation results in taking the logarithm of a negative number, which is undefined in the real number system. Therefore, [tex]\(w = 3\)[/tex] is extraneous, and the valid solution is [tex]\(w = 7\).[/tex]
In the detailed explanation, we used the property of logarithms that states [tex]\(\log(a) = \log(b)\)[/tex] implies [tex]\(a = b\)[/tex]. By setting the arguments of the logarithms equal to each other, we obtained a quadratic equation.
Factoring or applying the quadratic formula allowed us to find the solutions. However, we must always check for extraneous solutions by substituting them back into the original equation and ensuring the logarithms are defined for the real number system.
In this case, only [tex]\(w = 7\)[/tex] satisfies the equation without resulting in undefined logarithms.
Which statement is true about this argument?
Premises:
If a parallelogram has a right angle, then it is a rectangle.
Parallelogram PQRS has a right angle.
Conclusion:
Parallelogram PQRS is a rectangle.
The argument is not valid because the conclusion does not follow from the premises.
The argument is valid by the law of syllogism.
The argument is not valid because the premises are not true.
The argument is valid by the law of detachment.
The argument is valid by the law of detachment.
Answer:
The argument is valid by the law of detachment.
Step-by-step explanation:
We first verify that the first statement, "if p, then q" is correct. If a parallelogram has a right angle, this means that the angle opposite that angle must also be right; this is because the opposite angles of a parallelogram are congruent.
This also means that the adjacent angle to this right angle must also be right; this is because the adjacent angles in a parallelogram are supplementary.
Thus "if p, then q" is true.
The law of detachment states that if I have two statements, one of the form "if p, then q" and the other "p", then the conclusion, "q," is valid.

Hence, the value of x is [tex]\frac{3}{2}[/tex]
explain how you can compare the cost of two items that are different sizes
Answer:
First find the unit price for each. Then compare the unit prices. The item that has the lesser unit cost is the better buy.
Step-by-step explanation:
When comparing the costs of two items that are different sizes, use ratios to make a comparison and consider the unit size.
Explanation:When comparing the costs of two items that are different sizes, you can use ratios to make a comparison. Let's say Item A costs $10 and Item B costs $20. Item A is twice as expensive as Item B. To make the comparison fair, you can also consider the size or quantity of the items. For example, if Item A is twice as expensive but also twice as large as Item B, then the cost per unit size is the same. However, if Item A is half the size of Item B, then Item B is a better deal in terms of size.

In the measurement 0.503 l, which digit is the estimated digit? the 0 immediately to the left of the 3 5 the 0 to the left of the decimal point 3
Answer:
3.
Step-by-step explanation:
We are asked to find the estimated digit in the measurement 0.503 L.
We know that in each measurement the estimated digit is always the last digit.
We can see that the first digit in the given measurement is 5, the second digit is 0 and the last digit is 3.
Since the last digit is in our given measurement 3, therefore, the estimated digit is 3.

In how many ways can you place 8 rooks on a 8x8 chessboard so that no row or column contains more than one rook if
82=6482=64choices for that.
Now, for the second one, we can't be in the row or column of that first one, so leaving us with 72=4972=49 choices.
Then so on, we have 62=3662=36 for the third one, 2525 for the fourth one, and so on ……
But, however, we have to remember the rooks are not labeled, thus it doesn't matter specifically about a specific rook's position.
Thus, we have a total of (8!)28!=40320(8!)28!=40320 ways.

Find all numbers such that a third of a number increased by half that number is at least 3 less than that same number.
Answer:
All the numbers are less than and equal to 18.
Step-by-step explanation:
To find : All numbers such that a third of a number increased by half that number is at least 3 less than that same number ?
Solution :
Let the number be 'x',
A third of a number is [tex]\frac{x}{3}[/tex]
Half that number is [tex]\frac{x}{2}[/tex]
3 less than that same number is [tex]x-3[/tex]
A third of a number increased by half that number is at least 3 less than that same number is written as,
[tex]\frac{x}{3}+\frac{x}{2}\geq x-3[/tex]
[tex]\frac{2x+3x}{6}\geq x-3[/tex]
[tex]\frac{5x}{6}\geq x-3[/tex]
[tex]5x\geq 6x-18[/tex]
[tex]5x-6x\geq -18[/tex]
[tex]-x\geq -18[/tex]
[tex]x\leq 18[/tex]
Therefore, all the numbers are less than and equal to 18.
The set of numbers such that a third of a number increased by half that number is at least 3 less than that same number are given as; x <= 18.
According to the question;
Let the numbers in question be represented as x.
In essence;
[tex] \frac{x}{3} + \frac{x}{2 } \geqslant x - 3[/tex]
[tex] \frac{5x}{6} \geqslant x - 3[/tex]
5x >= 6x - 18-x >= -18x <= 18Therefore, the set of numbers such that a third of a number increased by half that number is at least 3 less than that same number are given as; x <= 18.

What method can be used to write the equation of a line in slope-intercept form given two points?
To write the equation of a line in slope-intercept form given two points, calculate the slope from the points, use one point and the slope to find the y-intercept, then write the equation as y = mx + b.
Explanation:To write the equation of a line in slope-intercept form, given two points, follow these steps:
Calculate the slope (m) using the formula m = (Y2 - Y1) / (X2 - X1), where (X1, Y1) and (X2, Y2) are the coordinates of the two given points.Once you have the slope, choose one of the two points to substitute into the slope-intercept form equation, y = mx + b, along with the slope you calculated. This will allow you to solve for the y-intercept (b).With both the slope and y-intercept, you can write the final equation of the line: y = mx + b.For example, if the two points given are (1, 3) and (4, 11), the slope would be (11 - 3) / (4 - 1) = 8 / 3. Then choosing the point (1, 3), we would substitute to find the y-intercept: 3 = (8/3)(1) + b, resulting in b = 3 - 8/3 = 1/3. So the equation of the line is y = (8/3)x + 1/3.
