Vertex of f(x)=x^2+12x+8

I'm pretty sure 4/10=40/100

Here is the equation:

[tex]\frac{3}{10} = \frac{30}{100} \rightarrow \frac{4}{10}  =\frac{x}{100}[/tex]

To find the missing number, you have to cross multiply. Here's the equation:

[tex]\frac{4}{10} = \frac{x}{100} \\ \\ 100 \times 4 = 10x[/tex]

Multiply:

[tex]100 \times 4 = 400 \\ 400 = 10x[/tex]

To leave the variable x alone, you need to divide both sides by 10

[tex]\frac{400}{10} = \frac{10x}{10}[/tex]

Divide:

[tex]400 \div 10 = 40 \\ x = 40[/tex]

Your answer is 40

7.5+12.5+2n

20+2n= Cost

The algebraic expression for the cost of Ms. Thomas's order is:

$2n + $20

Ms. Thomas ordered 5 pencil packs, n notebooks, and 5 sets of markers. We are asked to write an algebraic expression that represents the cost of Ms. Thomas's order. The cost of each item is given as follows:

Pencil pack: $1.50

Notebook: $2

Markers: $2.50

To write an algebraic expression for the cost of Ms. Thomas's order, we need to multiply the cost of each item by the number of items ordered, and then add the products together.

The cost of 5 pencil packs is 5 x $1.50 = $7.50.

The cost of n notebooks is n x $2 = $2n.

The cost of 5 sets of markers is 5 x $2.50 = $12.50.

Therefore, the algebraic expression for the cost of Ms. Thomas's order is:

$7.50 + $2n + $12.50

Simplifying this expression, we get:

$2n + $20

Therefore, the algebraic expression for the cost of Ms. Thomas's order is $2n + $20

Answer:

Corresponding angle theorem, vertical angle theorem, and the transitive property of congruence.

Step-by-step explanation:

Considering a set of parallel lines cut by a transversal. (Refer the attached image).

Now that lines J and K are parallel, then by "corresponding angle theorem"

[tex]\angle 1=\angle 5[/tex]

By "vertical angle theorem"

[tex]\angle 5 = \angle 7[/tex]

Using, "transitive property of congruence"

[tex]\angle 1 = \angle 7[/tex]

And that is our required proof. In this whole proof we have used "corresponding angle theorem", "vertical angle theorem", and the "transitive property of congruence".

Angles between a transversal line and parallel lines are congruent based on vertical angle theorem, corresponding angles and transitive property.

I will use the attached figure to explain the congruence of the angles.

A total of 812 tickets were sold for the school play. 375 adult tickets were sold.

Let's assume the number of adult tickets sold is "A" and the number of student tickets sold is "S."

We are given two pieces of information:

The total number of tickets sold is 812:

A + S = 812

There were 62 more student tickets sold than adult tickets:

S = A + 62

Now, we can set up a system of equations to represent the given information:

A + S = 812

S = A + 62

Now, we can solve the system of equations to find the values of A and S.

Substitute equation (2) into equation (1):

A + (A + 62) = 812

Combine like terms:

2A + 62 = 812

Subtract 62 from both sides:

2A = 812 - 62

2A = 750

Now, divide by 2 to solve for A:

A = 750 / 2

A = 375

Final answer:

375 adult tickets were sold.

Explanation:

Let's denote the number of adult tickets sold as x. According to the information provided, there were 62 more student tickets sold than adult tickets. So, the number of student tickets sold can be represented as x + 62.

Since a total of 812 tickets were sold, we can write the equation x + (x + 62) = 812. This equation represents the sum of adult tickets and student tickets being equal to the total tickets sold.

Solving this equation, we have 2x + 62 = 812. Subtracting 62 from both sides, we get 2x = 750. Then, dividing both sides by 2, we find that x = 375. Therefore, 375 adult tickets were sold.

I would say the answer would be B. or C.

not sure which but i hope i helped narrow it down..

Answer:

Its B

Step-by-step explanation:

For this case we have:

Part A:

Point 1: [tex](x1, y1) = (6,10)\\[/tex]

Point 2:[tex](x2, y2) = (4, -2)\\[/tex]

We know that the slope m is given by:

[tex]m = \frac{(y2-y1)}{(x2-x1)}\\\\m = \frac{(- 2-10)}{(4-6)}\\\\m = \frac{(- 12)}{(- 2)}\\[/tex]

[tex]m = 6\\[/tex]

The slope is [tex]m = 6\\[/tex]

Part b:

The equation of the line in point-slope form is given by:

[tex](y-y1) = m (x-x1)\\[/tex]

Substituting the point 1 [tex](x1, y1) = (6,10)[/tex]we have:

[tex](y-10) = 6 (x-6)\\[/tex]

Thus, the point-slope equation is: [tex](y-10) = 6 (x-6)\\[/tex]

Part c:

The equation of the line in slope-intersection form is given by:

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

Rewriting the equation of part b we have:

[tex]y = 6 (x-6) +10\\\\y = 6x-36 + 10\\\\y = 6x-26\\[/tex]

Thus, the equation of the line in slope-intersection form is

[tex]y = 6x-26\\[/tex]

Answer:

[tex]m = 6\\\\(y-10) = 6 (x-6)\\\\y = 6x-26[/tex]

Given : Invested amount = $5000.

Rate of interet = r% compunded monthly.

Number of years = 4 years.

Total interest received = $1866.

Therefore, total amount after 4 years = 5000+1866 = $6866.

We know, formula for compound interest :

[tex]A=P(1+\frac{r}{n})^{t\times n}[/tex], where P is the invested amount, n is the number of monthly installments in an year.

Number of months in an year are 12.

Plugging n=12, P=5000, t=4 in the formula now, we get

[tex]6866=5000{(1+\frac{r}{12})^{12\times 4}[/tex]

[tex]6866=5000{(1+\frac{r}{12})^{48}[/tex]

Dividing both sides by 5000, we get

[tex]\frac{6866}{5000} =\frac{5000}{5000} {(1+\frac{r}{12})^{48}[/tex]

[tex]\frac{6866}{5000} = {(1+\frac{r}{12})^{48}[/tex]

[tex]1.3732= {(1+\frac{r}{12})^{48}[/tex]

Taking 48th root on both sides, we get

[tex]\sqrt[48]{1.3732} = \sqrt[48]{(1+\frac{r}{12})^{48}}[/tex]

[tex]\sqrt[48]{1.3732}=\left(1+\frac{r}{12}\right)[/tex]

[tex]1.00662903758=1+\frac{r}{12}[/tex]

Subtracting 1 from both sides, we get

0.00662903758 = [tex]\frac{r}{12}[/tex]

Multiplying by 12 on both sides, we get

r=0.07954845101

r≈0.0795

Or 7.95%.

Now, we need to find the interest after four years if the rate of interest is 3.6% compounded quarterly.

There are 4 quarters in an year.

So, n=4 and r=3.6%= 0.036.

Plugging values in compound interest formula now, we get

[tex]A=5000{(1+\frac{0.036}{4})^{4\times 4}[/tex]

[tex]\mathrm{Divide\:the\:numbers:}\:\frac{0.036}{4}=0.009[/tex]

[tex]A=5000\times \:1.009^{16}[/tex]

[tex]A=5000\times \:1.15414\dots[/tex]

[tex]=5770.70222\dots[/tex]

A≈5770.70

Subtracting 5770.70 -5000.00 = 770.70.

The object of any equation with a variable (whether it is on one side or both) is to isolate the variable.  We do this by moving all of the x's to one side of the equation and everything else to the other side.

For example:

3x - 5 = 2x + 1

-2x         -2x    

 x  - 5 =         1

    +5           +5

x         =         6

Now, there are 3 different types of solutions:

1) x = ____  there is one solution

2) 0 = 0   or some other TRUE statement  there are infinite solutions because every value for x is a solution

3) 0 = 1   or some other FALSE statement  there are no solutions because no value for x will provide a solution

C) (x – 2)(x + 2)(x² + 4)(x⁴ + 16)

Step-by-step explanation:

The difference of squares is factored like this:

... a² - b² = (a - b)(a + b)

The given expression is the difference of squares:

... (x⁴)² - (2⁴)²

so can be factored as ...

... (x⁴ - 2⁴)(x⁴ + 2⁴) . . . . . . . 2⁴=16

Once again, the difference term is the difference of squares, so it can be factored as ...

...  x⁴ - 2⁴ = (x² -2²)(x² + 2²) . . . . . . 2²=4

And the difference in the first factor is also the difference of squares and can be factored.

... x² -2² = (x - 2)(x + 2)

Putting each factorization in its place in the whole expression, we get

... x⁸ - 256 = (x - 2)(x + 2)(x² +4)(x⁴ +16)
