Step-by-step explanation:

domain and range are x and y so you find all the y's

Answer:

B

Step-by-step explanation:

On edge

Answer:

[tex] y = x^2+14x +(14/2)^2 +8 - (14/2)^2[/tex]

And solving we got:

[tex] y = x^2 +14x +49 + 8 -49[/tex]

And we can reorder the terms we got:

[tex] y =(x+7)^2 -41[/tex]

And that would be the equivalent expression for the problem

Step-by-step explanation:

For this case we have the following function given:

[tex] y = x^2 +14x +8[/tex]

And we can complete the square adding the middle of 14 squared and subtracted before like this:

[tex] y = x^2+14x +(14/2)^2 +8 - (14/2)^2[/tex]

And solving we got:

[tex] y = x^2 +14x +49 + 8 -49[/tex]

And we can reorder the terms we got:

[tex] y =(x+7)^2 -41[/tex]

And that would be the equivalent expression for the problem

Answer:

x = 8 cm

Step-by-step explanation:

A = l x L

6cm×4cm = 3cm×xcm

x = 24cm²/3cm

x = 8 cm

Answer:

Step-by-step explanation:

Answer:

48cm^2

Step-by-step explanation:

We are given some of the measurements of the piece of cardboard.

First, let's find the lengths of all the sides of the cardboard, as it will be easier to then find the area.

Going in clockwise order, from top to bottom, the dimensions are:

4cm, 7cm, 6cm, 2cm, 10cm, 9cm.

Now, we can easily find the area by using the formula BH=Area. Let's split the cardboard into sections that will be easier to find the area of. Say we split it in two, rather like a sneaker with the person wearing a sock showing at the ankle (I have strange explanations, I know).

To find the top part (the sock part) we can multiply 4 by 7 to get 28.

To find the shoe part, we can multiply 10 by 2 to get 20.

Finally, add these areas together to get the total area.

20 + 28 = 48

Another way to do this (if my sock and sneaker explanation was too chaotic for you) would be to imagine that the cardboard piece were an entire rectangle (ignore that chunk that has been cut out).

The area of that would be 90, from 9 by 10 as the side lengths. Then, from earlier, we know that the width and length of the chunk that has been cut out is 6 and 7, so the area that will be cut out is 42.

Subtract 42 from 90 to get 48.

Answer:

25%

Step-by-step explanation:

So first calculate how many numbers are above 10.

There are 10

There are only 5 even numbers.

The fraction is: [tex]\frac{1}{4}[/tex] = 25%

( C. ) m + 1 = 2

Step-by-step explanation:

m + 1 = 2

⇒ m = 2 - 1

⇒ m = 1

Answer:

Substitute

Step-by-step explanation:

After you get an answer to an equation, you can substitute your answer into the equation to check to see if it's correct.

Options A and B are steps to complete an equation, not to check it.

Option C should be correct.

[tex]x+5=16\\x+5-5=16-5\leftarrow \text{Subtraction Property of Equality} \\x=11[/tex]

We can substitute 11 into the equation to check if it's correct.

[tex]11+5=16\\\boxed{16=16}[/tex]

Our answer is correct.

Answer:

B) combine like terms

Step-by-step explanation:

When you combine like terms, you have to consider all and need to plug in your answer into the original equation to check.

Answer:

Option D

Step-by-step explanation:

The  Associative Property of Multiplication allows you to group numbers in any combination, and still get the correct answer from it.

[tex]a(b*c)=(a*b)c[/tex]

Option D '(3 x 6) x 2 = 3 (6 x 2)​' has the same numbers, but 3 and 6 are grouped while 6 and 2 are grouped on the other side.

[tex]a*(b*c)=(a*b)*c\rightarrow(3 * 6)*2 = 3*(6 * 2)[/tex]

Option D should be the correct answer.

Answer:

about 4.17 hours

Step-by-step explanation:

To solve the time for each class, you do 2.5 hours divided by 3. Then you take this value and multiply by 5 since there are 5 classes. After you do this, you should get 4.17 hours roughly.

No, Sam will not be able to finish the large hamburger if he only bites 20% of what is left.

In mathematics, a percentage is defined as a figure or ratio expressed as a fraction of 100. The percent sign, "%," is commonly used to indicate it.

Let the size of the hamburger be 100 units.

Here, the first bite was 20% of the hamburger.

So the remaining portion of the hamburger is 100 - (100*(20/100)) = 80 units.

The second bite was 20% of 80%. Again the remaining portion is 80 - (80*(20/100)) = 80 - 16 = 64 units.

After the third bite, the remaining portion is 64 - (64*(20/100)) = 64 - 12.8 = 51.2 units.

After the fourth bite, the remaining portion is 51.2 - (51.2*(20/100)) = 51.2 - 10.24 = 40.96 units.

After the fifth bite, the remaining portion is 40.96 - (40.96*(20/100)) = 40.96 - 8.192 = 32.768 units.

...

Since the criterion is Sam will bite 20% of what is left, this remaining portion is never zero. It will always be a fraction like 0.00000000000001. Again we have to find 20% of 0.00000000000001 and subtract it from 0.00000000000001. So, It will continue.

Therefore, we can conclude that it is not possible for Sam to eat the big hamburger all if he will bite 20% of what is left.

Answer:

True

Step-by-step explanation:

Answer:

True

Step-by-step explanation:

Answer:

y = (1/3)x + 7  

Step-by-step explanation:

Steps:

  (y-y1)=m(x-x1)     where m=slope

Using (x1,y1) is (-6,5):

1:  (y-5)= (1/3)(x-(-6))

2:   (y-5) = (1/3)(x+6)

3:     y-5 = (1/3)x + 2           Distribute

4:  y = (1/3)x + 7             Add 5 to both sides

Hope this helps.

The solution is, the value of x in the equation. 24 = 2x – 9 is: x=16.5.

Simplify simply means to make it simple. In mathematics, simply or simplification is reducing the expression/fraction/problem in a simpler form. It makes the problem easy with calculations and solving.

here, we have

given that, the equation is, 24 = 2x – 9

now, we have to simplify the equation to get the value of x.

24=2x-9

Add 9 to each side

33=2x

Divide both sides by 2

i.e. 33/2 = x

16.5=x

Hence, The solution is, the value of x in the equation. 24 = 2x – 9 is: x=16.5.

[tex]\sqrt{64}[/tex]=±8

Answer:

B. -8 and 8

Step-by-step explanation:

To solve this equation, we need to get x by itself. To do this, perform the opposite of what is being done to the equation. Keep in mind everything must be done to both sides of the equation.

x^2=64

x is being squared. The opposite of being squared is taking the square root. Take the square root of both sides.

√x^2=√64

The exponent and square root on the left will cancel, and x will be left by itself.

x=√64

x=±8

The solutions of the equation are x=8 and x= -8

Therefore, the answer is B. -8, 8

The answers are

A) If a figure has point symmetry, it also must have rotational symmetry  

D) All parallelograms have point symmetry

E)  A triangle never has point symmetry

on Edge 2020

A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.

Point Symmetry is when every part has a matching part the same distance from the central point but in the opposite direction. It looks the same when viewed from opposite directions (180° rotation).

1) A figure has point symmetry, if it has a rotational symmetry of 180 degrees.

2) An object is said to possess rotational symmetry if it takes the same shape before and after its rotation along its point of rotation.

3) In order for a figure to have reflectional symmetry, there needs to be at least one axis such that when the the figure "folds" over that axis it maps into itself.

4) A parallelogram has rotational symmetry. A parallelogram does not have reflectional symmetry.

So, all parallelograms have point symmetry.

5) Triangle has no points of symmetry, because there is no up and down shapes in triangle

A parallelogram has rotational symmetry and triangle has no points of symmetry. Therefore, option 4 and 5 are correct answers.
