Answer:

So a point is (-3,-5) and the vertex is (-4,-3)

Step-by-step explanation:

This is in vertex form. Vertex form is y=a(x-h)^2+k where (h,k) is the vertex.

The vertex here is (-4,-3)... now just use a value of x to plug in (any value besides -4)

I will choice -3.  This gives -2(-3+4)^2-3

f(-3)=-2(1)^2-3

f(-3)=-2-3

f(-3)=-5

So a point is (-3,-5) and the vertex is (-4,-3)

Answer:(-4,-3)

Step-by-step explanation:

Hi!

To solve this, first let's decide what quadrant the 135 degrees lies in. Starting in quadrant one, it would end up landing in quadrant 2.

Coordinates:

(cos, sin)

In quadrant 2, the y value (sin) as a coordinate would be positive, therefore our final answer should be positive.

180 - 135 = 45

Therefore our reference angle will be sin45.

We should know that sin45 is equal to [tex]\cfrac{\sqrt{2} }{2}[/tex]

Now, remember that our final answer should be positive. We don't have to change this because it's already positive, so your final answer is:

[tex]\cfrac{\sqrt{2} }{2}[/tex]

The exact value of sin 135 degrees is - (√2)/2.

The unit circle and trigonometric identities can be used to calculate the sine of 135 degrees.

We can determine the location of the point on the unit circle that corresponds to an angle of 135 degrees by utilizing the unit circle. It is located in the third quadrant.

In the first and second quadrants, the sine function is positive; however, the third and fourth quadrants are where it is negative.

We can use the fact that the sine of an angle equals the y-coordinate of the point on the unit circle corresponding to that angle to determine the precise value.

The sine of 135 degrees is negative because the third quadrant's y-coordinate is negative.

We can determine the precise sine value of 135 degrees by using a reference angle.

In the third quadrant, the reference angle for 135 degrees is 45 degrees (180 degrees - 135 degrees).

The sine of a 45-degree angle is (2)/2 or 1/sqrt(2).

The sine of 135 degrees is a negative number because the reference angle is in the third quadrant.

Consequently, (2)/2 is the precise value of sin 135 degrees.

Answer:

A

Step-by-step explanation:

Step-by-step explanation:

This equation is written in standard form, y = ax² + bx + c.

a = 1 , b = -2 , c = -4

First, the x² tells you that this is going to be a parabola. Since the a is positive, the parabola will be facing up (with the ends pointing up).

Next, you find the axis of symmetry, or vertex, which is where the middle of the parabola is. The formula for this is [tex]\frac{-b}{2a}[/tex].

[tex]\frac{-(-2)}{2(1)}[/tex]   Simplify

[tex]\frac{2}{2}[/tex]   Simplify

1

So, the middle of your parabola will be at x = 1.

Now, find the x-intercept. Since the x-intercept of a graph is where y = 0, just plug 0 into the equation for y.

y = x² - 2x - 4   Plug in 0

0 = x² - 2x - 4   Factoring won't work, so use the Quadratic Formula.

[tex]$x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$[/tex]   Plug in[tex]$x=\frac{-(-2)\pm\sqrt{(-2)^2-4(1)(-4)}}{2(1)}$[/tex]   Simplify

[tex]$x=\frac{2\pm\sqrt{4+16}}{2}$[/tex]   Simplify

[tex]$x=\frac{2\pm\sqrt{20}}{2}$[/tex] The square root of 20 is about 4.47.

[tex]$x=\frac{2+4.47}{2}$[/tex] and [tex]$x=\frac{2-4.47}{2}$[/tex]   Simplify

x = 3.235 and -1.235

These are your x-intercepts, where your parabola crosses the x-axis.

Now, just put all of this information together on a graph!

[tex]\bf \textit{vertex of a vertical parabola, using coefficients} \\\\ y=\stackrel{\stackrel{a}{\downarrow }}{1}x^2\stackrel{\stackrel{b}{\downarrow }}{-4}x\stackrel{\stackrel{c}{\downarrow }}{+6} \qquad \qquad \left(-\cfrac{ b}{2 a}~~~~ ,~~~~ c-\cfrac{ b^2}{4 a}\right) \\\\\\ \left(-\cfrac{-4}{2(1)}~~,~~6-\cfrac{(-4)^2}{4(1)} \right)\implies (2~~,~~6-4)\implies (2~,~2)[/tex]

Answer:

B. (2,2).

Step-by-step explanation:

Convert to vertex form y = a(x - b)^2 + c where (b, c) is the vertex.

y =x^2 - 4x + 6

y = (x - 2)^2 - 4 +6

y = (x - 2)^2 + 2.

Therefore the vertex is (2, 2).

Step-by-step explanation:

A suitable graphing or scientific calculator can find the reduced row-echelon form for you. There are on-line calculators that will do that, too.

_____

In general, if you want to do this by hand, you want to use row operations on the augmented matrix to make the diagonal elements 1 and the off-diagonal elements 0 as shown in the attached result.

If a[i,j] represents the element at row i, column j, you do that by dividing row i by a[i, i] (to make a[i, i] = 1), then subtracting the product of row i and a[k,i] from row k. (for all rows k ≠ i) For this 3-row matrix, repeat these steps for i = 1 to 3.

In the general case of an n by n+1 augmented matrix, you will be doing n^2 row operations, each one involving evaluation of n+1 expressions. The work rapidly grows with matrix size, so readily justifies use of a calculator.

As with many "elimination" problems, appropriate choice of sequence can reduce the work. The above algorithm always produces the reduced row-echelon form, but may result in messy arithmetic along the way.

Answer:

  (x, y) = (-3, 5)

Step-by-step explanation:

There are many ways to solve a system of two equations with two unknowns. Almost all of them involve reducing the system to one equation in one unknown. (Graphical solution, as in the attachment, bypasses that algebraic manipulation.)

In general, the first step is to look at the equations to see if ...

If the first condition is true, then the system may be easily solved by "substitution." The expression you have for one of the variables can be substituted for that variable in the other equation.

If the second condition is true, you can add the equations to eliminate the variable with opposite coefficients. (Opposites add to give zero.)

Here, the third condition holds: the coefficient of x in the first equation (4) is simply related to the coefficient of x in the second equation (8) by a factor of 2.

___

So, we can eliminate the x-variable from the system of equations by multiplying the first equation by -2 and adding that result to the second equation:

  -2(4x +2y) +(8x +5y) = -2(-2) +(1)

  -8x -4y +8x +5y = 4 +1 . . . . eliminate parentheses

  y = 5 . . . . . . . . . . . . . . . . . . . collect terms

Now, we can substitute this value into either equation to find the value of x. Using the first equation, we get ...

  4x +2(5) = -2

  4x = -12 . . . . . . . subtract 10

  x = -3 . . . . . . . . . divide by 4

The solution to the system of equations is (x, y) = (-3, 5).

Answer:

Step-by-step explanation: You are given the equation of -7x+6y=9 and -2x-5y=16 and you are asked to find what x=? and what y=?

First step is to write down the problem

-2x-5y=16

next add 5y over the equal sign.

-2x=5y+16

Next is too divide by -2

-2x/-2=5y+16/-2

after solving you get

x=-2.5y-8

now you substitute the equation into the other formula to get

-7(-2.5y-8)+6y=9

then solve by doing -7*-2.5y and -7*-8 to get 17.5y and 56 which will give you

17.5y+56+6y=9

Next you subtract 56 to the other side to get 9-56 or -47 now you have

17.5y+6y=-47

next is too add the 17.5y and 6y together to get 23.5y

23.5y=-47

next is too divide by 23.5

23.5y/23.5=-47/23.5

solve to get y=-2, now this is half you the problem

Step two is too substitute what y=-2 into the equation of x=-2.5y-8 to get

x=-2.5(-2)-8

Solve to get

x=5-8

Solve again to get

x=-3

Your answers are x=-3 and y=-2

Answer:

x = -3 and y = -2

Step-by-step explanation:

It is given that,

-7x + 6y = 9

   ----(1)

-2x - 5y = 16    -------(2)

To find the solution of given equations

eq(1) * 2 ⇒

-14x + 12y = 18 ------(3)

eq(2) * 7 ⇒

-14x - 35y = 112   ---(4)

eq (3) - eq(4) ⇒

-14x + 12y = 18 ------(3)

-14x - 35y = 112   ---(4)

    0   4y = -94

y = 94/(-47) = -2

Substitute the value of y in eq (2)

-2x - 5y = 16    -------(2)

-2x - 5*-2 = 16

-2x +10 = 16

-2x = 6

x = 6/-2 = -3

Therefore x = -3 and y = -2

Final answer:

To find when the costs are the same for both ski resorts, set up an equation based on their rates and solve for the number of hours, which in this case is 1 hour.

Explanation:

To determine at what point the cost of both Bunny Hill Ski Resort and Black Diamond Ski Resort is the same, we can set up an equation based on the given rates.

Let x be the number of hours spent skiing. Then the total cost at Bunny Hill Ski Resort is $35 (ski rental) plus $10 per hour (hourly rate), which is expressed as 35 + 10x.

Similarly, the cost at Black Diamond Ski Resort is $40 (ski rental) plus $5 per hour (hourly rate), or 40 + 5x. To find when the costs are equal, we set the two expressions equal to each other:

35 + 10x = 40 + 5x

Now we can solve for x:

35 + 10x = 40 + 5x
10x - 5x = 40 - 35
5x = 5
x = 1

Thus, after 1 hour of skiing, the cost of skiing at both resorts becomes the same.

Answer:

(-2, 4)

Step-by-step explanation:

One of the equations is already solved for y, so let's solve the other one for y and by the transitive proprerty of equality, if y = y, then what those y's are equal to are equal to each other.  Solving the first equation for y:

x + y = 2 so

y = -x + 2

Let's fill that in for y in the second equation.  Where

[tex]y=\frac{1}{2}x+5[/tex], making the substitution,

[tex]-x+2=\frac{1}{2}x+5[/tex]

Combining like terms and getting the x on one side and the constant on the other side of the equals sign:

[tex]-\frac{3}{2}x=3[/tex]

The product of a fraction and its reciprocal is 1 so we will multiply both sides by

[tex]-\frac{2}{3}[/tex] to get:

[tex](-\frac{2}{3})(-\frac{3}{2})x=(3)(-\frac{2}{3})[/tex]

and we end up with x = -2.

Now that we know that, we can sub that in for x in either one of the original equations.  I chose the first one:

If x + y = 2, then -2 + y = 2

and y = 4

Therefore, the solution set is (-2, 4)

Step-by-step explanation:

If Heather bought markers to donate, the amount she donates is subtracted from her balance of 45.71.  We know she bought 6 packs of markers, but we do not know how much each pack cost.  We will make this our unknown "x".  The expression for  packs of markers costing "x" is 6x.  Because she buys them from her account, which takes aways from her balance, the expression that represents this donation is:

45.71 - 6x

(Notice that the question asks for the EXPRESSION after she buys the markers, not the EQUATION.  The difference between an expression and an equation is the lack of an equals sign in the expression.)

Answer:

[tex]a_{n-1}[/tex] = 4[tex]a_{n}[/tex]

Given a₄ = 2 [tex]\frac{1}{4}[/tex], then

a₃ = 4 × a₄ = 4 × 2[tex]\frac{1}{4}[/tex] = 9

a₂ = 4 × a₃ = 4 × 9 = 36

a₁ = 4 × a₂ = 4 × 36 = 144

The first four terms for the given series will be 144, 36, 9, and 2(1/4) respectively.

When there is a constant between the two successive numbers in the series then it is called a geometric series. In other words, every next term is multiplied with that constant term to form a geometric progression.

The recursive formula allows us to find a term in a sequence from the previous term.

Given

[tex]a_n=\dfrac{a_n-1}{4}[/tex]

Given the fourth term, we require to work back to the third term, second, and so on. Rearrange the formula to give.

Multiply both sides by 4, then

a[tex]_{n-1}[/tex] = 4a[tex]._n[/tex]

Given a₄ = 2, then

The first four terms will be calculated as given below:-

a₃ = 4 × a₄ = 4 × 2 = 9

a₂ = 4 × a₃ = 4 × 9 = 36

a₁ = 4 × a₂ = 4 × 36 = 144
