a. Nina is correct, because the formula P = 2l + 2w would be a correct perimeter formula. Alexander, however, is wrong, because the formula P = 2(l + w) would be an incorrect perimeter formula.

b. P = L + L + W + W would be another correct perimeter formula, as it is the same thing to P = 2l + 2w.

c. One reason the paint was empty after their calculations were correct would be because of their argument before determining the perimeter amount of paint that they need. Another reason the paint was empty after their calculations were correct was because of the fact that they probably don't know how to perfectly do the paint within the perimeter.

Answer:

When x = 0, the value of f(x) is -3

Each time x increases by 1, f(x) increases by 2

f(x) = 2x - 3

Step-by-step explanation:

✔️From the graph given, values of x is plotted in the horizontal axis while values of f(x) is plotted on the vertical axis.

Thus:

When x = 0, the value of f(x) is -3. => (0, -3)

✔️Each time x increases by 1, f(x) increases by 2. i.e. when x increases from 3 to 4 on the y axis, f(x) increases from 3 to 5 on the why axis.

✔️The equation that models the function can he written in the form of f(x) = ax + b, where:

a = rate of change = rise/run

b = y-intercept = the point on the y-axis that the line intercepts.

Rate of change between the two points on the line (0, -3) and (4, 5):

Rate of change (a) = rise/run = (5 - (-3))/(4 - 0) = 8/4

a = 2

b = y-intercept = -3

✅To write the equation, substitute a = 2 and b = -3 into f(x) = ax + b:

f(x) = 2x + (-3)

f(x) = 2x - 3

C.52

Step-by-step explanation:

In a parallelograms opposite sides are congruent

This means that side SP = side RQ as they are opposites

Hence 1/4y = 13

Note that we've just created an equation that we can use to solve for y.

We now solve for y algebraically using the equation we've just created

1/4y = 13

Divide both sides by 1/4

1/4y / 1/4 = y

13 / 1/4 = 52

We're left with y = 52

If PQRS is a parallelogram, the value of y in the parallelogram PQRS is 52. Therefore, option C, 52, is the correct answer.

To find the value of y in the parallelogram PQRS, we can use the properties of parallelograms.

In a parallelogram, opposite sides are equal in length. Therefore, PQ is equal to RS, and QR is equal to SP.

Given that PQ = 11 and RS = 11, we can conclude that QR = SP.

Substituting the given values, we have:

1/4 y = 13

To isolate y, we multiply both sides of the equation by 4:

4 * (1/4 y) = 4 * 13

This simplifies to:

y = 52

Using the property of a parallelogram where opposite sides are equal, we determine that QR is equal to SP. Substituting the given values, we find that 1/4 y is equal to 13. By multiplying both sides of the equation by 4, we isolate y and find that its value is 52.

Therefore, option C, 52, is the correct answer.

Answer:

[tex]\boxed {\boxed {\sf y= 6x+5}}[/tex]

Step-by-step explanation:

We are asked to find the slope-intercept equation of a line. Slope-intercept form is one way to write the equation of a line. It is:

[tex]y=mx+b[/tex]

Where m is the slope and b is the y-intercept.

We are given a point (-1, -1) and the line is parallel to the line y= 6x-2. Since the line is parallel to the other line, they have the same slope, which is 6. We have a point and a slope, so we should use the point-slope formula to find the equation of the line.

[tex]y-y_1= m (x-x_1)[/tex]

Here, m is the slope and (x₁, y₁) is the point. We know the slope is 6 and the point is (-1, -1). Therefore:

Substitute the values into the formula.

[tex]y- -1 = 6(x- -1) \\y+1= 6(x+1)[/tex]

Distribute the 6. Multiply each value inside the parentheses by 6.

[tex]y+1 = (6*x)+ (6*1) \\y+1= 6x+6[/tex]

Slope-intercept form requires y to be isolated. 1 is being added to y. The inverse of addition is subtraction. Subtract 1 from both sides.

[tex]y+1-1=6x+6-1 \\y= 6x+5[/tex]

The equation of the line in slope-intercept form is y=6x+5

This is called "completing the square"

It is a technique to  solve a quadratic equation. It involves "moving all

of the constants to the right" , then doing a "move" on the left hand side. This move "creates a perfect square".. This is done by taking 1/f of the "B" term and squaring it... this will "un-balance" the  sides of the equation... to balance it out you have to "add" some stuff to the right hand side... when done the left side will be "a perfect square" .. last step will be take the square root of both sides.

Step-by-step explanation:

[tex]x^2 + 12x + 15 = 0[/tex]

[tex]x^2 + 12x + 15 -15 = -15[/tex]

[tex]x^2 + 12x = -15[/tex]

[tex]b = 12 ... (1/2 b)^2 = 6^2 = 36[/tex]

[tex]x^2 + 12x + 36 = -15 + 36[/tex]

[tex]x^2 + 12x + 36 = 21[/tex]

[tex](x+ 6)^2 = 21[/tex]

[tex]\sqrt{(x+ 6)^2 } =[/tex] ± [tex]\sqrt{21}[/tex]

[tex]x+ 6[/tex]= ± [tex]\sqrt{21}[/tex]

x = -6 ±[tex]\sqrt{21}[/tex]

Answer:

Step 1: -15

Step 2: b = 12, c = 36

Step 3-4: x² + 12x + 36 = -15 + 36, which simples to (x + 6)² = 21

If there is a step that has you solve for x, it should be -6 + √21 or -6 - √21.

Step-by-step explanation:

Step 1 is pretty simple. All we have to do is subtract 15 from 0 to get the first blank.

x² + 12x = 0 - 15

x² + 12x = -15

Step 2:

b is the coefficient on x, which is 12.

Then, use the formula mentioned:

[tex]c = ( \frac{b}{2})^{2} \\ c = ( \frac{12}{2} )^{2} \\ c ={6}^{2} \\ c = 36[/tex]

As a result of that, c is 36.

Now to substitute and simplify. (Steps 3-4)

x² + 12x + 36 = -15 + 36

To factor an equation, think about it like this: Find two numbers that add to the coefficient of x, and multiply to the constant. So what two numbers add to 12, and multiply to 36? That would be 6 & 6 (6 + 6 = 12; 6 × 6 = 36).

(x + 6)² = -15 + 36

Add 36 to -15 to get 21.

(x + 6)² = 21

That should solve steps 1-4, but I will go on ahead and give the final answer to the entire problem.

(x + 6)² = 21

Yes, you are about see what I just factored be expanded back over again. It's part of the process.

x² + 12x + 36 = 21

Now subtract 21 from both sides.

x² + 12x + 36 - 21 = 21 - 21

x² + 12x + 15 = 0

Now onto the hard part of this: the quadratic formula. a = (the understood) 1, b = 12, and c = 15.

x = (-b ± √b² - 4ac)/2a

x = -12 ± √12² - 4(15)/2

x = -12 ± √144 - 60/2

x = -12 ± ✓84/2

x = -6 + √21 or -6 - √21

Replace every copy of "w" with "x"

So the function we graph is y = (1500-2x)*x/2

I used GeoGebra to make the graph below. Note the scale on the xy axis. In this case, x is incrementing by 100 while y is incrementing by 50,000. The scale is important so you have a good viewing window. You don't have to have this scale exactly, but something close to it should do the trick. Without the proper scale, you probably won't see the curve at all. You may see a straight line instead, or it may appear completely blank.

You can use Desmos to make the graph. Just keep in mind the scale of course.

Once you have the graph set up, use the max feature of your graphing calculator or graphing software to locate the vertex point. In GeoGebra, the function I used is "Max". I typed in Max(f, 0, 800) where f is the function mentioned earlier. With Desmos, you simply need to click on the curve itself to have the max point show up. Click on the vertex point to have the coordinates listed.

The max point is located at A = (375, 140625) as shown in the diagram below. The x coordinate is the value of "w" that we replaced earlier. So a width of w = 375 feet corresponds to the max area of 140625 square feet.

Side note: later on in your math career, you have the option to use calculus to solve a problem like this. Though for now, we can rely on a graphing calculator to get the job done quickly.

y = (x-15)/-8

Step-by-step explanation:

When solving for an inverse function, swap x and y without bringing the x coefficient with it, just simply swap the variables. Then, solve for y, and that's it.

y = -8x + 15

x = -8y + 15

x-15 = -8y

(x-15)/-8 = y

Step-by-step explanation:

Hey there!

Given function is: y = -8x + 15

~ Interchange"X" and "y".

x = -8y + 15

~ Solve it

8y = 15-x

y = (15-x)/8

Therefore, the inverse of function is y = (15-x)/8.

The orchard sold 72 apples, which represents 12% of the total number of apples they put up for sale. The total number of apples they put up for sale is 600.

Use the concept of percentage defined as:

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.

Given that,

The orchard sold 72 apples.

The 72 apples represent 12% of the total number of apples they put up for sale.

To find out the total number of apples the orchard put up for sale,

use a simple equation.

Let's denote the total number of apples as "x".

According to the given information,

72 apples represent 12% of the total number of apples.

Set up the equation as follows:

12% of x = 72

To solve for x, convert the percentage to a decimal.

12% is equivalent to 0.12.

0.12 x = 72

Now, solve for x by dividing both sides of the equation by 0.12:

x = 72 / 0.12

x = 600

Hence,

The total number of apples they put up for sale is 600.
