This method is not appropriate because of the mathematical sign separating the terms. It is supposed to be minus not a plus sign

The expression by factoring out the greatest common factor is 4(x^2-9)

Given the expression 4x^2 + 36. According to the difference of two square,

a^2 - b^2 = (a-b)(a+b)

For the expression 4x^2 + 36, this can also be written as:

= (2x)^2 + 6^2

= (2x+6)(2x-6)

This method is not appropriate because of the mathematical sign separating the terms. It is supposed to be minus not a plus sign

Using the factoring method:

4x^2 = 4 * x^2

36 = 4 * 9

Since 4 is common to both of the terms, hence;

4x^2 + 36 = 4(x^2+9)

Hence the expression by factoring out the greatest common factor is 4(x^2-9)

Answer:

point form:(2,-2),(-3,13)

Step-by-step explanation:

You solve for the first variable in one of the equations, then substitute the result into the other equation.

Answer:

13, 4, and 4

Step-by-step explanation:

The absolute value of a difference measures the discrepancy between the two numbers inside.  The 13 represents the ideal amount of biscuits and x represents the actual number of biscuits in the package.  So the difference between the actual and the ideal is 4 (whether it's 4 more of 4 less than 13).

The situation described doesn't actually match the wording, because this says there'll either be 9 or 17 biscuits in the package, due to the "=".  If you wanted to have "as many as," then this should be "≤", allowing for 4 or fewer in either direction.

Answer:

$15

Step-by-step explanation:

The price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35). The maximum revenue is $170,625.

To find the price that would minimize the store's revenue, we need to determine the price at which the wig sales would be maximized.

Let's assume the price increase in dollars is represented by "x" (where x > 0).

The number of wigs sold can be calculated using the given information: for each $1 increase in price, 75 fewer wigs are sold.

So, the number of wigs sold at the price of $30 + x would be 3000 - 75x.

The revenue is calculated by multiplying the price per wig by the number of wigs sold. Therefore, the revenue function (R) can be expressed as:

R = (30 + x)(3000 - 75x)

To find the price that would minimize the store's revenue, we need to find the value of x that minimizes the revenue function. We can do this by finding the critical points of the revenue function.

To find the critical points, we differentiate the revenue function with respect to x and set it equal to zero:

dR/dx = 0

Differentiating R = (30 + x)(3000 - 75x) with respect to x:

dR/dx = (3000 - 75x) + (30 + x)(-75) = 0

Expanding and simplifying:

3000 - 75x - 2250 - 75x = 0

Combine like terms:

-150x - 5250 = 0

Solving for x:

-150x = 5250

x = 5250 / (-150)

x = -35

Since x represents the price increase, a negative value of x would correspond to a price decrease. So, the price that would minimize the store's revenue is $30 - $35 = -$5 (a price decrease of $5).

However, a negative price is not practical in this context. So, we should consider the price increase instead.

Therefore, the price that would minimize the store's revenue is $30 + $35 = $65 (a price increase of $35).

To find the maximum revenue, we can substitute this price ($65) back into the revenue function:

R = (30 + 35)(3000 - 75 * 35)

Simplifying:

R = 65 * 2625

R = $170,625

Therefore, the maximum revenue is $170,625.

The function graphed below is option C.

A function is a relation from a set A to a set B where the elements in set A only maps to one and only one image in set B. No elements in set A has more than one image in set B.

Given is a piecewise function.

Piecewise functions are function which has different values for different intervals.

Here the two pieces of the function corresponds to the intervals x > 1 and x ≤ 1.

Since the closed circle is over the curve below, we denote the interval x ≤ 1.

Now, from the options, the intervals x > 1 and x ≤ 1 are mentioned in options B and C.

For, x > 1, the graph is increasing. That is, as x value increases y value must increase.

So the equation cannot be x³ - 4.

Hence the option is C.

Hence the correct option is C.
