<em>Quadratic equation, vertex shape, parabola </em>

For this case we have to rewrite the given quadratic equation, in the form of vertex, for this, we must take into account that a quadratic equation of the form ax ^ 2 + bx + c = 0, can be rewritten in the form of vertex as: y = a (x-h) ^ 2 + k. Vertice is the lowest or highest point of the parabola. The vertex is given by: (h, k). So, let: f (x) = 4x ^ 2 + 48x + 10, to find the equation in the form of vertex, we follow the steps below:

Step 1:

We take the common factor to the first two terms of the equation:

f (x) = 4 (x^2 + 12x) + 10

Step 2:

We work square:

We divide the coefficient of the term "12x" by 2 and its result is squared, that is:

(\frac {12} {2}) ^ 2 = 36

So, we have:

f (x) = 4 (x^2 + 12x + 36-36) + 10

Step 3:

We simplify:

f (x) = 4 (x^2 + 12x + 36) + 10- (4 * 36)

Step 4:

We factor:

f (x) = 4 (x + 6) ^ 2-134

Thus, h = -6\ and\ k = -134

Answer:

The equation in the form of vertex is: f (x) = 4 (x + 6) ^ 2-134, and the vertex is (h, k) = (- 6, -134)

The local movie theater reported loses of $175 each day for three days. What was the loss for the fourth day?
laila [671]
Answer: $700
explanation: they lost 175 EACH DAY
so 175 x 3 = 525
add another 175 for the fourth day
525 +175 = 700
They lost a total of $700 on the fourth day.

Which classification describes the following system of equations? inconsistent and dependent consistent and dependent consistent
sveta [45]

The system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have three linear equations in three variables:

x - y - z = 0 ..(1)

2x - y + 2z = 1 ..(2)

x - y + z = -2 ..(3)

From the equation (1):

\rm x=y+z

Plug this value in the equation (2) and (3):

\rm 2\left(y+z\right)-y+2z=1\\\\ y+z-y+z=-2

After solving we get:

z = -1

y = 5

Plug the above two values in equation (1) we get:

x = 4

Thus, the system of equations is consistent and independent and the solutions are x = 4, y = 5, and z = -1 option third is correct.

Find the equation of the line that is perpendicular to the line x = −5 and passes through the point (1, π).
Tanzania [10]

The line x = -5 is a vertical line, therefore the line perpendicular to this line is the horizontal line of the form y = a.

We know that it passes through the point (1, π) → x = 1, y = π.

Therefore we have answer: A) y = π.
