Answer 1

Answer:

Answer:

option C

Step-by-step explanation:

$4c^2 + 7c - 5 = 0 , \ where \ a = 4 , \ b = 7 , \ x = - 5$

$c = (- b \pm √(b^2 - 4ax ))/(2a) \n\nc = (- 7 \pm √(49 - ( 4 * 4 * - 5 )))/(2 * 4) \n\nc = (- 7 \pm √(49 + 80))/(8) \n\nc = (- 7 \pm √(49 + 80))/(8) \n\nc = (- 7 \pm √(129))/(8) \n\n$

Answer 2

Answer:

Answer:

Option C

Step-by-step explanation:

Quadratic formula:

$4c^(2) +7c-5=0$

$a=4\nb=7\nx=-5$

$c=\frac{-b\frac{+}{} √(b^2-4ax)}{2a}$

$c=\frac{-7\frac{+}{}49-(4*4*-5) }{2*4}$

$c=\frac{-7\frac{+}{}√(129) }{8}$

Hello, there are three questions and pictures of them in the links If you could solve them that would be awesome, thank you!

Answers

Answer:

1. 1 * $x^(3/6)$ = $x^(3/6)$ (it will be equal to the sixth root of x cube)

2. No, the expression $x^(3)$ X $x^(3)$ X $x^(3)$ will be equal to $x^(3 + 3 + 3 )$ since the powers of numbers with the same base are added

3. B and D 1/ $x^(-1)$ is the same as 'x'

as mentioned in the last answer, powers of numbers with same base are added. hence, option D will be $x^(3/3)$ which will be equal to x

On a coordinate plane, an absolute value graph has a vertex at (1, negative 2.5). The graph shows the function f(x) = |x – h| + k. What is the value of k? k = –2.5 k = –1 k = 1 k = 2.5

Answer:

(a) k = –2.5

Step-by-step explanation:

When the function f(x) is transformed to f(x -h) +k, the graph is translated h units right and k units up.

If the absolute value function has its original vertex of (0, 0) moved to (1, -2.5), then (h, k) = (1, -2.5).

The value of k is -2.5.

Additional comment

The above answer applies to the given problem statement. The question asked in the comment has a vertex of (0, 2.5), so (h, k) = (0, 2.5) for that question.

If you're going to copy the answer, make sure it is the answer to the question you're looking at.

In an absolute value function expressed as f(x) = |x – h| + k, the value of k corresponds to the y-coordinate of the function's vertex. In this case, as the vertex is at the point (1, -2.5), the value of k is -2.5.

The student's question relates to the concepts of Two-Dimensional (x-y). Graphing and the graphing of the absolute value function. It is vital to remember that the vertex of an absolute value graph in the form f(x) = |x – h| + k corresponds to the point (h, k) on the Cartesian coordinate plane. The student states that the vertex is at the point (1, -2.5), so based on our function analysis, the value of k, which represents the y-coordinate of the vertex, is -2.5. Therefore, the correct answer is k = -2.5.

A rectangle with an area of 324 square meters has a length and width in a ratio of 4:1. What are the length and width?

Answers

Here, 4x * x = 324
Now, we need to calculate that unit of x value as follows:
4x * x = 324
4x² = 324
x² = 324/4
x² = 81
x = √81
x = 9
So, 4x = 4(9) = 36

So, dimensions of rectangle would be: 36 × 9

NEED HELP PLEASEEEEEEEEEEEPoints A′, B′, and C′ are the images of 180-degree rotations of A, B, and C, respectively, around point O.

Answers

Answer:

35 degrees

Step-by-step explanation:

Final answer:

Points A', B', and C' are the images of 180-degree rotations of points A, B, and C, respectively, around point O. These rotations involve equal angles but different arc lengths due to the varying distances from the center of rotation.

Explanation:

When objects rotate about some axis, each point in the object follows a circular path. In the given question, points A', B', and C' are the images of 180-degree rotations of points A, B, and C, respectively, around point O. These rotations are represented by the angles AO, BO, and CO.

Since all three rotations are 180 degrees, the angles AO, BO, and CO are equal. However, the arc lengths As2, Bs2, and Cs2 are not equal because the points A', B', and C' move through greater arc lengths due to their greater distance from the center of rotation.

Therefore, the rotation of points A, B, and C results in the images A', B', and C' moving through the same angle AO, but covering different arc lengths As2, Bs2, and Cs2 due to their varying distances from the center of rotation.

Liam is a rewards member at a local restaurant. He can buy four tacos at regular price and get 5.50 off of his purchase. Zachary found a coupon to buy three tacos at regular price and get 6.50 off his total. What would the taco price x need to be in order for Liam and Zachary to spend the same amount?

Answers

Liam can buy 4 tacos at regular price and get 5.50 off of his purchase while Zachary can buy 3 tacos at regular price and get 6.50 off his total.

There is no price of the taco that makes that both of them spend the same.

Liam and Zachary buy tacos at the same place. Let "x" be the price of each taco and "y" be the total amount spent.

Liam can buy 4 tacos at regular price and get 5.50 off of his purchase.

We can represent the situation through the following linear equation.

y = 4x - 5.50 [1]

Zachary found a coupon to buy three tacos at regular price and get 6.50 off his total.

We can represent the situation through the following linear equation.

y = 3x - 6.50 [2]

We want to know the prices of the taco so that both of them spend the same amount.

We calculate it making [1] equal to [2].

4x - 5.50 = 3x - 6.50

4x - 3x = -6.50 + 5.50

x = -1.00

The taco would have cost -1.00 for both of them to spend the same. Since in reality, this is unlikely, we can say that there is no price of the taco that makes that both of them spend the same.

Liam can buy 4 tacos at regular price and get 5.50 off of his purchase while Zachary can buy 3 tacos at regular price and get 6.50 off his total.

There is no price of the taco that makes that both of them spend the same.

Which property is shown in the matrix addition below?
[-6 15 -2 ] + [6 -15 2 ] = [0 0 0

Answers

Answer:

The property shown in matrix addition given is "Additive Inverse Property"

Step-by-step explanation:

First of all lets define what a matrix is.

A matrix is an array of rows and columns that consists of numbers. There are several types of matrices. The one in our question is a row matrix which consists of only one row.

There are several addition properties for matrices.

One of them is additive inverse property. The additive inverse of a matrix consists of the same elements but their signs are changed.

Additive inverse property states that the sum of a matrix and its additive inverse is a zero matrix.

$\left[\begin{array}{ccc}-6&15&-2\end{array}\right] + \left[\begin{array}{ccc}6&-15&2\end{array}\right] = \left[\begin{array}{ccc}0&0&0\end{array}\right]$

Hence,

The property shown in matrix addition given is "Additive Inverse Property"
