Answer:

x=-2

Step-by-step explanation:

11=-4x+3

8=-4x

8/-4=-4x/-4

-2=x

Answer:

Point B

Step-by-step explanation:

In the graph of y = f(x),

For every x-value (input value), value of the function is the y-value (output value).

For the input value x = -2,

Output value of the function will be,

y = 2

f(-2) = 2

Therefore, point B will represent the input-output values of the function.

Step-by-step explanation:

The quadrilateral is a parallelogram if and only if it has two pairs of parallel sides option (D) is correct.

In two-dimensional geometry, it is a plane shape having four sides, in which two pairs of sides are parallel to each other and equal in length. The sum of all angles in a parallelogram is 360°.

It is given that:

A parallelogram is a quadrilateral with two pairs of parallel sides.

As we know,

The quadrilateral can be defined as the four-sided polygon in geometry having four edges and four corners.

The quadrilateral, has:

Two pairs of congruent sides.

It has one pair of opposite congruent angles.

The diagonals of a kite are perpendicular.

One diagonal is bisected.

The top and bottom angles are bisected but does not have congruent diagonals.

A quadrilateral is a parallelogram if and only if it has two pairs of parallel sides.

Thus, the quadrilateral is a parallelogram if and only if it has two pairs of parallel sides option (D) is correct.

Answer:

[tex]y = x^2 - 5x - 14[/tex]

Step-by-step explanation:

Given

[tex]x = -2[/tex] and [tex]x = 7[/tex]

Required

Determine the quadratic equation with a leading coefficient of 1

First, we equate both expression to 0

[tex]x = -2[/tex] and [tex]x = 7[/tex]  becomes

[tex]x + 2 = 0[/tex] and [tex]x - 7 = 0[/tex]

Multiply both expressions:

[tex](x + 2) * (x - 7) = 0 * 0[/tex]

[tex](x + 2) (x - 7) = 0 * 0[/tex]

Open Brackets

[tex]x^2 - 7x + 2x - 14 = 0[/tex]

[tex]x^2 - 5x - 14 = 0[/tex]

Hence, the quadratic equation is:

[tex]x^2 - 5x - 14 = 0[/tex]

or

[tex]y = x^2 - 5x - 14[/tex]

The formula, in standard form y = ax^2 + bx + c, for a quadratic that has roots at x = -2 and x = 7 is y = x² - 5x + 14

Given the standard form of quadratic equation expressed as [tex]ax^2 + bx+c =0[/tex]

If a quadratic that has roots at x = -2 and x = 7, then their factors will be x+ 2 and x - 7.

Taking the product of the factors will give:

f(x) = (x+2)(x-7)

f(x) = x² - 7x + 2x - 14

f(x) = x² - 5x + 14

Hence the formula, in standard form y = ax^2 + bx + c, for a quadratic that has roots at x = -2 and x = 7 is y = x² - 5x + 14

Answer:

(-5) * (20) * (3)

Step-by-step explanation:

Diving 5 feets deeper = descent = negative 5 Feets

Each time instrument is checked = (60/3) = depth of 20 feets

Number of times instrument is checked = 3

Hence, maximum depth :

Diving 5 feets deeper * Each time instrument is checked = depth of 20 feets * Number of times instrument is checked

(-5) * (20) * (3) = - 60

               Not executable

Step-by-step explanation:

f(x) = a(x - h)² + k      - vertex form of the equation of the parabola with vertex (h, k)

so the equation of parabola with the vertex (24, 10) is  :

f(x) = a(x - 24)² + 10  

the parabola's axis of symmetry parallel to the y-axis and passing through point (4,290) means:  h = 4

That  means you write something wrong in your question.

Answer:

Option (B)

Step-by-step explanation:

From the graph attached,

x-intercepts of the graphed function are,

x = -3 and x = 4

Therefore, zero factors of the function will be,

(x + 3) and (x - 4)

So the quadratic function given in the graph will be in the form of,

f(x) = (x + 3)(x - 4)

Option (B) will be the correct option.

The rectangular coordinates (√3,√3) and polar coordinates (√6,[tex]\frac{\pi}{4}[/tex]) represent the same complex number z=x+iy because,

[tex]r=\sqrt{(\sqrt3)^2+(\sqrt3)^2}=\sqrt6[/tex] and,

[tex]\theta=\arctan(\frac{\sqrt3}{\sqrt3})=\arctan(1)=\frac{\pi}{4}[/tex]

The question is not written in an understandable manner look at the question in the below-given image.

In terms of Cartesian coordinates, the polar coordinates r (the radial coordinate) and θ (the angular coordinate, often known as the polar angle),

x = rcosθ

(1)

y = rsinθ, 

(2)

where r is the radial distance from the origin and θ is the counterclockwise angle from the x-axis. In relation to x and y,

[tex]r=\sqrt{x^2+y^2}[/tex]

(3)

[tex]\theta=\arctan(\frac{y}{x})[/tex]

Using the above explanation of polar coordinates we have that

[tex]r=\sqrt{(\sqrt3)^2+(\sqrt3)^2}=\sqrt6[/tex] and

[tex]\theta=\arctan(\frac{\sqrt3}{\sqrt3})=\arctan(1)=\frac{\pi}{4}[/tex]

320 * 12 = 3,840 hours

Mr. and Mrs. Miller work a total of 3,840 hours per year. Therefore in order to meet their budget, they need to make an hourly wage of ...
