Answer:

Step-by-step explanation:

First, let's find the equation of the line.

Use points (0, -2) and (1, 2) on the graph.

The y-intercept is (0, -2), find the slope:

The line is:

Now, we see the line is dotted and the space to the left side is shaded.

Dotted line means the inequality doesn't include the points on the line, therefore the sign would be > or <.

Since the left side of the line includes greater values of the function, it should have > sign.

So the inequality is:

Answer:

im not so sure..but you can look at yt videos, they help a lot :)

The sine of the angle = the length of the opposite side. the length of the hypotenuse.

The cosine of the angle = the length of the adjacent side. the length of the hypotenuse.

Answer: y=2x+4

You first find slope which is y2-y1 divided by x2-x1 that gives you slope and then you put it into the formula y-y1=m(x-x1)

Larger number = 21.5

Step-by-step explanation:

One number = x

Larger number = x + 2

x + x +2 = 41

2x + 2 = 41

       2x = 41 - 2

       2x = 39

         x = 39/2

         x = 19.5

Larger number = x + 2

                        = 19.5 +2

                        = 21.5

Answer:

It would take hans around 5 hours to drive 275

Step-by-step explanation:

first we divide 715 by 13 which gives us 55, so in 1 hour he can drive 55 miles then we do 275 divided by 55 which gives us 5, so the answer is 5.

At the rate 55 miles per hour, it takes 5 hours to travel 275 miles.

Given that, Hans drove 715 miles in 13 hours.

Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.

Here, average speed = 715/13

= 55 miles per hour

At the same rate,

Time = 275/55

= 5 hours

Therefore, at the rate 55 miles per hour, it takes 5 hours to travel 275 miles.

Answer:

x² - 12x + 36

Step-by-step explanation:

Given

(x - 6)² = (x - 6)(x - 6)

Each term in the second factor is multiplied by each term in the first factor, that is

x(x - 6) - 6(x - 6) ← distribute both parenthesis

= x² - 6x - 6x + 36 ← collect like terms

= x² - 12x + 36

Answer:

Line 2 and 3 are parallel

Step-by-step explanation:

Recall that the general equation of a line in slope-intercept form is given by:

y = mx + b

where m is the gradient (slope).

two different equations that have the same value of m is said to have the same gradient and hence are parallel.

We simply have to rearrange each given equation so that it takes the form

y = mx + b and then compare all 4 to see which values of m are the same.

Line 1 :  y = -7x + 6

Line 2: x +(1/5)y=-6 ===> rearrange to get y = -5x - 30

Line 3:  y= -5x -8

Line 4:  y+7=(-1/7)(x+4) ===> rearrange to get y = (-1/7)x - (53/7)

comparing the above, it is clear that line 2 and line 3 have m- values of m = -5, hence these lines are parallel.

Step-by-step explanation:

The second graph is the inverse secant function.

To find graph of the inverse secant function.

Inverse trigonometric functions are simply defined as the inverse functions of the basic trigonometric functions which are sine, cosine, tangent, cotangent, secant, and cosecant functions.

The reciprocal cosine function is secant: sec(Ф)=1/cos(Ф). The reciprocal sine function is cosecant, cosec(Ф)=1/sin(Ф).

So, the second graph is the inverse secant function.

Answer:

The the linear equation in point-slope form is

[tex]y-3 = -2 (x-4)[/tex]

Step-by-step explanation:

Given

We know that the point-slope form of the line equation is

[tex]y-y_1=m\left(x-x_1\right)[/tex]

Here:

substituting the values m = -2 and the point (4, 3) in the point-slope form

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y-3 = -2 (x-4)[/tex]

Thus, the the linear equation in point-slope form is

[tex]y-3 = -2 (x-4)[/tex]

Note: This equation could be further simplified to write it in the slope-intercept form

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

where m is the slope and b is the y-intercept

so writing the equation in the slope-intercept form

[tex]y-3 = -2 (x-4)[/tex]

[tex]y-3 = -2x+8[/tex]

[tex]y=-2x+8+3[/tex]

[tex]y=-2x+11[/tex]

Translation

Step-by-step explanation:

Translation is when something moves or slide. Orientation refers to the way it is facing or turned.

The required given statement is Reflections is transformations always preserve the orientation of a figure.

A transformation is a general term for four specific ways to manipulate the shape and/or position of a point, a line, or geometric figure. The original shape of the object is called the Pre-Image and the final shape and position of the object is the Image under the transformation.

Given:

The given statement is which transformations always preserve the orientation of a figure.

According to given question we have

Reflection is a type of transformation in which the given image is flipped across a line of reflection to create the transformed image. In this transformation, dimensions of the figure is always preserved.

In a translation, the preimage and image have the same orientation. In a rotation, the orientation of the preimage is changed. Both are rigid transformations.

Therefore, the required given statement is Reflections is transformations always preserve the orientation of a figure.

Answer:

Step-by-step explanation:

If you plot the vertex and the directrix, you'll see that the directrix is a horizontal line above the vertex. That means that the parabola opens upside down and has the standard equation:

[tex](x-h)^2=-4p(y-k)[/tex] where h and k are the coordinates of the vertex and p is the number of units between the directrix and the vertex. From the vertex we determine that h = 6 and k = 2. And by counting, we determine that p = 2. Filling in the equation then gives us:

[tex](x-6)^2=-4(2)(y-2)[/tex] and simplifying just a tiny bit will get us what we need:

[tex](x-6)^2=-8(y-2)[/tex] which is the second choice down.

The equation of this parabola in standard form is (x - 6)²  = -8(y - 2) if the vertex of a parabola is (6,2) option (C) is correct.

It is defined as the graph of a quadratic function that has something bowl-shaped.

(x - h)² = 4a(y - k)

(h, k) is the vertex of the parabola:

a = √[(c-h)² + (d-k²]

(c, d) is the focus of the parabola:

It is given that:

The vertex of a parabola is (6,2), and the equation of its directrix is y = 4.

The standard form of the parabola:

y = a(x - h)² + k

y = a(x - 6)² + 2

As the directrix is y = 4

The equation of the parabola becomes:

(x - 6)²  = -8(y - 2)

Thus, the equation of this parabola in standard form is (x - 6)²  = -8(y - 2) if the vertex of a parabola is (6,2) option (C) is correct.
