The price charged depends on the size of the window.

Option (B) is correct.

What is a direct proportion?

Direct proportion is a relationship between two variables, where the ratio of their values is always constant. This means that if one variable increases, the other variable will also increase in the same ratio.

B) The price charged depends on the size of the window.

The statement that is true is that the price charged by David for cleaning windows depends on the size of the windows. It means that the larger the window, the more David charges for cleaning it. The size of the window is a factor in determining the price and not the other way around.

Hence, the correct statement would be "The price charged depends on the size of the window.".

The end behavior of a function is the way the graph of the function behaves as either x→∞ or x→−∞.

To calculate the end behavior of a function, we take the highest degree of the function and look at the leading coefficient. If the leading coefficient is positive, then the graph will go to positive infinity as x→∞ and will go to negative infinity as x→−∞. If the leading coefficient is negative, then the graph will go to negative infinity as x→∞ and will go to positive infinity as x→−∞. For example, if the function is f(x) = 2x^3 + 6x, then the highest power is 3 and the leading coefficient is 2, which is positive. Therefore, the graph of the function will go to positive infinity as x→∞ and will go to negative infinity as x→−∞.

Isolating x in the second equation, the expression that would be replaced into the first equation to solve the system of equations is given as follows:

b. -3y + 12.

The system of equations for this problem, with variables x and y, is defined as follows:

The second equation of the system is given as follows:

-x - 3y = -12.

The first step to isolate x is move the -3y term to the opposite side of the equality, with an addition symbol, which is the inverse of the negative symbol, hence:

-x = 3y - 12.

As the leading coefficient of x is negative, the entire expression must be multiplied by -1, hence:

x = 12 - 3y.

x = -3y + 12(commutative property).

Meaning that the correct option is given by option b.

Answer: (b) -3y + 12.

To use the Substitution Method, we would isolate x in the second equation, which gives:

-x = 3y - 12

Multiplying both sides by -1, we get:

x = -3y + 12

We can then substitute this expression for x into the first equation, which gives:

2(-3y + 12) + y = 8

Simplifying this expression, we get:

-5y + 24 = 8

Subtracting 24 from both sides, we get:

-5y = -16

Finally, dividing both sides by -5, we get:

y = 16/5

Therefore, if we isolate x in the second equation, we would substitute x = -3y + 12 into the first equation.

So the expression we would substitute into the first equation is -3y + 12.

The factor of xy 3y − 7x − 21 is x − 3.

xy 3y − 7x − 21 = x(y 3y − 7) − 21 = x(y 3y − 7) − 3(7) = (x − 3)(y 3y − 7)

The expression xy 3y − 7x − 21 can be simplified by factoring out the greatest common factor, which in this case is x. We can factor out an x by dividing the entire expression by x. This gives us y 3y − 7 − 21/x. Now, we can look for a common factor between the two terms. In this case, the factor is -3. We can factor out -3 from both terms to get -3/x and y 3y − 7. This can be rewritten as (x − 3)(y 3y − 7). Therefore, the factor of xy 3y − 7x − 21 is x − 3.

To explain further, factoring is the process of breaking down an expression into its factors. A factor is a number, variable, or expression that can be multiplied to produce the original expression. In this case, we are looking for the factors of xy 3y − 7x − 21. To find these factors, we first simplify the expression by factoring out the greatest common factor, which in this case is x. We then look for a common factor between the two terms, which is -3. We factor out -3 and rewrite the expression as  

(x − 3)(y 3y − 7). This means that the factor of xy 3y − 7x − 21 is x − 3.

D =b^2 - 4ac.

if D<0 then equation have no solution.

Option B:

The discriminant of the quadratic equation 3x^2 - 5x + 4 is the value of b^2 - 4ac, which is (5)^2 - 4(3)(4) = 25 - 48 = -23. A negative discriminant (-23) would indicate that the equation has no real solutions, meaning it has no solutions in real numbers.

The value of 2 ½ is 2.5. As 2 ½ is the same as mixed fraction 2 ½ = 5/2.

2 ½ is a mixed number, it is a whole number combined with a fraction. In this case, 2 is the whole number and ½ is the fraction. The value of 2 ½ is calculated by adding the value of the whole number to the value of the fraction.

The value of the whole number 2 is 2, and the value of the fraction ½ is 0.5. To find the value of 2 ½, we add 2 to 0.5:

2 + 0.5 = 2.5

So, the value of 2 ½ is 2.5.

It's important to note that mixed numbers are used to represent numbers that are between two whole numbers, they consist of a whole number and a proper fraction. This mixed number representation is commonly used in everyday life, and it's easy to understand.

Answer:

B) y = -2/3x -2

Step-by-step explanation:

The equation is y = mx + b

m = the slope

b = y-intercept

The slope = rise/run

Let's pick 2 points (-3,0) (0, -2); we see the y decrease by 2 and the x increase by 3, so the slope is

m = -2/3 = -2/3

The Y-intercept is located at (0, -2)

So, our answer is B) y = -2/3x -2

The y10 is a linear function, which is a type of function that follows a straight line when graphed.

Linear functions are often written in the form y = mx + b, where m is the slope of the line and b is the y-intercept.

The equation y 10 is a linear function with a slope of 0, meaning that the line does not move up or down and a y-intercept of 10, meaning that the line passes through the point (0, 10).

The function y 10 is a mathematical expression that can be used to solve certain equations. It is a linear equation, which means that it follows the equation y = mx + b, where m is the slope of the line and b is the y-intercept.

The slope of the given linear equation y = 2x + 10 is 2.

If we draw the graph of the linear equation y = mx + c. The result is a line with m as the slope, and c as the y-intercept. This form of the linear equation y = mx + c is called the slope-intercept form, and the values of m and c are real numbers.

The slope, m, of the line represents the steepness of a line. This is also termed a gradient, sometimes. The y-intercept, c, of the line y = mx + c represents the y-coordinate of the point where the graph of the line intersects the y-axis.

Now, if we equate the standard slope-intercept form of the equation with the given equation, we get

y = mx + c

y = 2x + 10

m = 2 and c = 10

As we know the m is the slope which is equal to 2.
