Explanation:

The equation that does not support the fact that polynomials are closed under multiplication is 1x⋅x=1. When multiplying two polynomials, the degree of the resulting polynomial is the sum of the degrees of the two original polynomials. In this case, the degree of the resulting polynomial would be 2, but the equation implies a polynomial of degree 0, which is not possible.

Answer:

Cost of each cherry pie = $6

Cost of each blackberry pie = $16

Step-by-step explanation:

Let x be the cherry pies and y be the blackberry pie.

Solution:

From the above statement Jasmine sold 12 cherry pies and 4 blackberry pies for a total of $136.

So, we write the first equation as.

[tex]12x+4y = 136 ------(1)[/tex]

And Stephanie sold 8 cherry pies and 1 blackberry pie for a total of $64.

So, we write the second equation as.

[tex]8x+y = 64 --------(2)[/tex]

First we solve equation 2 for y.

[tex]y = 64-8x[/tex] ------------------------(3)

Substitute [tex]y = 64-8x[/tex]  in equation 1.

[tex]12x+4(64-8x) = 136[/tex]

[tex]12x+256-32x=136[/tex]

[tex]12x-32x=136-256[/tex]

[tex]-20x=-120[/tex]

[tex]x=\frac{120}{20}[/tex]

x = 6

Substitute x = 6  in equation 3.

[tex]y = 64-8(6)[/tex]

[tex]y=64-48[/tex]

y = 16

Therefore, cost of each cherry pie = $6 and cost of each blackberry pie = $16

By solving the system of equations, it is determined that the cost of one cherry pie is $6 and the cost of one blackberry pie is $16. These findings are crucial for pricing strategies in the school fundraiser.

To solve the system of equations for the cost of cherry and blackberry pies sold by Jasmine and Stephanie for a school fundraiser, we can set up two equations based on the given information:

Let's denote the cost of one cherry pie as c and the cost of one blackberry pie as b. Therefore, we can form the following equations based on the problem statement:  

Using the method of substitution or elimination, we solve for c and b.

For simplicity, let's use elimination. To eliminate b, we can multiply the second equation by -4 and add to the first:

-32c - 4b = -256
12c + 4b = 136

Combining these, we get -20c = -120, thus c = $6. Substituting c = 6 into the second equation, 8*6 + b = 64, gives us b = $16.

In real-life terms, this means one cherry pie costs $6, and one blackberry pie costs $16, which would be important for pricing and accounting in the fundraiser.

Answer:

False

Step-by-step explanation:

Factors of 10 and 14:

10:  1 , 2, 5, 10

14:  1, 2, 7, 14

As you can see, 5 is not a common factor of 10 and 14

The greatest common factor is two

So the answer is false, 5 is not the greatest common factor of 10 and 14

Hope this helps :)

The greatest common factor of 10 and 14 is 2, not 5. The statement is false as 5 is not a factor of 14.

The greatest common factor (GCF) of two numbers is the largest number that divides both of them without leaving a remainder. To find the GCF of 10 and 14, we list the factors of each number:

The common factors of 10 and 14 are 1 and 2. Therefore, the GCF of 10 and 14 is 2, not 5. The statement that the greatest common factor of 10 and 14 is 5 is false.

Answer: X = 28

Step-by-step explanation: The diagram shows a triangle which is actually in fact, two triangles placed into each other. The first one is triangle APR (the larger one) while the second one is triangle CDR (the smaller one).

Also the diagram shows line AP as being parallel to line CD. That makes triangle APR similar to triangle CDR.

We can now determine the ratios of the similar sides

If triangle APR = triangle CDR, then

Line PD/DR = AC/CR or

PD/PR = AC/AR or

CD/RD = AP/RP

Therefore to calculate X, we use the ratio,

PD/DR = AC/CR

15/42 = 10/x

{we reduce the left hand side to it's simplest form}

5/14 = 10/x

When we cross multiply we now have

5x = 14 × 10

5x = 140

Divide both sides of the equation by 5

x = 28

Domain: [tex][-2,6][/tex]

Range: [tex][0,5][/tex]

Explanation:

Domain:

The domain of a function is the set of all possible values of the independent variable x. From the graph, we can see that the function has the set of all possible values from -2 to 6. Hence, the domain is from -2 to 6.

Thus, writing the domain in interval notation, we have,

[tex]-2\leq x\leq 6[/tex]

This also can be written as [tex][-2,6][/tex]

Hence, the domain is [tex][-2,6][/tex]

Range:

The Range of a function is set of all possible values of y obtained by substituting the values for x in the function. From the graph, we can see that the function has the set of all possible values from 0 to 5. Hence, the range is from 0 to 5.

Thus, writing the range in interval notation, we have,

[tex]0\leq y\leq 5[/tex]

This also can be written as [tex][0,5][/tex]

Hence, the range is [tex][0,5][/tex]

The domain and range in interval notation represent sets of possible values a function can take. For instance, for the function f(x) = 2x + 3 where x can be any real number, both the domain and range would be (-∞, ∞). Square brackets denote inclusive endpoints, while parentheses denote exclusive endpoints in interval notation.

In mathematics, particularly in functions, the domain and range represent sets of possible input and output values respectively. When expressed in interval notation, domain and range convey a concise representation of these sets.

Let's illustrate with an example. If we have the function f(x) = 2x + 3, and x can be any real number, the domain in interval notation would be (-∞, ∞). As for the range, since the function can also output any real number, the range would also be (-∞, ∞).

To write the domain and range in interval notation, remember that square brackets [ ] represent inclusive endpoints, while parentheses ( ) represent exclusive endpoints. The symbol '∞' is always cloaked by parentheses.

Answer:

150

Step-by-step explanation:

We know that Scott's ratio of making the basket is 9/12. All we need to do is find out how many baskets he'll make if he attempts 200 shots.

So, 9/12 needs to become x/200. We don't know what x is yet, but there's a shortcut.

9/12 can be simplified by dividing 3 on the top and bottom.

9/12 ÷ 3/3 = 3/4

We can then see how many times 4 can go into 200.

200/4 = 50

So, we multiply 3/4 by 50 on both the top and bottom.

3/4 × 50/50 = 150/200.

So, if he attempts 200 shots then he'll make 150 of them.

Scott can expect to make approximately 150 baskets if he attempts 200 shots with his success rate being 9 out of 12, which equates to a 75% success rate.

The question asks how many baskets Scott can expect to make if he tries 200 shots given that his average success rate is 9 out of 12. To find the answer, we can set up a proportion because Scott's shooting is a matter of probability and ratios. First, we determine Scott's success rate as a fraction: 9/12 which simplifies to 3/4 or a success rate of 75%.

Then, we apply this success rate to the new number of attempts (200) to find the expected number of successful baskets:

Therefore, if Scott attempts 200 shots, he can expect to make approximately 150 baskets.

Step-by-step explanation:

The question is asking about the inverse of a function, a crucial mathematical concept. We generally calculate this by switching x and y, then solving the new equation for y. Without specific function options, we cannot provide a correct answer.

The question is about determining the inverse of a function, an important concept in Mathematics. Given that the question does not have any specifics about the function itself, it's impossible to determine the correct answer. In general, to find the inverse of a function, we follow a certain procedure: exchange the roles of y and x; once that is done, solve the function for y.

For instance, if you had a function like f(x) = 2x + 3, the inverse would be calculated by flipping x and y and solving the resulting equation for y: x = 2y + 3. Solving for y, you have y = (x - 3) / 2.

angle list: k,l,j:

sides are:  LJ, KJ, KL

To find the sides of triangle JLK in order from smallest to largest, we need to compare the measures of the angles. The side opposite the largest angle is the longest side, so we can determine the order of the sides based on the angle measures.

The triangle JLK has angles J, L, and K with measures 82, 57, and 41 degrees, respectively. To determine the sides of JLK in order from smallest to largest, we can use the fact that the side opposite the largest angle is the longest side. So, we need to identify the largest angle and its corresponding side.

Comparing the measures of the angles, we can see that M∠J is the largest angle. Therefore, the side opposite angle J, which is side JL, is the longest side. Next, we compare the measures of the remaining angles. M∠L is the next largest angle, so the side opposite angle L, which is side LK, is the second longest side. Finally, M∠K is the smallest angle, so the side opposite angle K, which is side JK, is the shortest side.

Therefore, the sides of triangle JLK in order from smallest to largest are JK, LK, JL.

Hey there!

When we say (f + g)(2), we are adding both functions together and plugging in 2 for x.

Since f(x) is equal to 2x + 210 and g(x) is equal to 2x + 125, (f + g)(x) is equal to (2x + 210) + (2x + 125).

That can be simplified to 4x + 335.

So, (f + g)(x) = 4x + 335.

Let's plug 2 in for x and solve.

(f + g)(2) = 4(2) + 335
