Answer:

2  +   + 1 6

Step-by-step explanation:

Add the numbers:

6 + 5y - 4y + 10 + 3x -x    =  

1 6  +  5  −  4  +  3   −

Combine like terms:

16 + 5y - 4y +3x - x

16+ 1y + 3x -x

Multiply by 1

16 + 1y + 3x - x

16 + y + 3x - x

Combine like terms:

16 + y + 3x - x

16 + y + 2x

Rearrange terms:

16 + y + 2x

2x + y + 16

Answer:

16 + y + 2x

Step-by-step explanation:

[tex]6 + 5y - 4y + 10 + 3x - x[/tex]

[tex]16 + 5y - 4y + 3x - x[/tex]

[tex]5y - 4y = (5 - 4)y = 1y = y[/tex]

[tex]16 + y + 3x - x[/tex]

[tex] = 16 + y + 2x[/tex]

Step-by-step explanation:

In geometry, transformation involves changing the position and/or size of a shape.

The coordinate notations are:

Both transformations are not rigid

[tex]7.\ \triangle ABC \to \triangle A'B'C'[/tex]

Using coordinates A and A', as a reference;

We have:

[tex]A = (6,6)[/tex]

[tex]A' = (3,3)[/tex]

Divide A' by A to get the scale ratio (k)

[tex]k = \frac{A'}{A}[/tex]

[tex]k = \frac{(3,3)}{(6,6)}[/tex]

Factorize

[tex]k = \frac{(3,3)}{2 \times (3,3)}[/tex]

[tex]k = \frac{1}{2}[/tex]

Hence, the coordinate notation is:

[tex](x,y) \to (\frac{1}{2}x,\frac{1}{2}y)[/tex]

Calculate distance AB and A'B' using:

[tex]d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2}[/tex]

So, we have:

[tex]AB = \sqrt{(6 - 4)^2 +(6 - -2)^2} = \sqrt{68}[/tex]

[tex]A'B' = \sqrt{(3 - 2)^2 +(3 - -1)^2} = \sqrt{17}[/tex]

Because

[tex]AB \ne A'B'[/tex]

We've confirmed that the transformation is not rigid

[tex]8.\ \triangle FGH \to \triangle F'G'H'[/tex]

Using coordinates F and F';

We have:

[tex]F = (-1,1)[/tex]

[tex]F' = (-2,1)[/tex]

Divide the x-coordinate of F' by F to get the scale ratio (k) because the y-coordinates of the pre-image and the image are the same

[tex]k = \frac{F'}{F}[/tex]

[tex]k = \frac{-2}{-1}[/tex]

[tex]k = 2[/tex]

Hence, the coordinate notation is:

[tex](x,y) \to (2x,y)[/tex]

Calculate distance FG and F'G' using:

[tex]d = \sqrt{(x_2 - x_1)^2 +(y_2 - y_1)^2}[/tex]

So, we have:

[tex]FG = \sqrt{(-1 - 1)^2 +(1 - -1)^2} = \sqrt{8}[/tex]

[tex]F'G' = \sqrt{(-2 - 2)^2 +(1 - -1)^2} = \sqrt{20}[/tex]

Because

[tex]FG \ne F'G'[/tex]

We've confirmed that the transformation is not rigid

Hi there!

Given;

f(x) = 5x-1

Now; Simply keep the value of x in the given function.

f(1) = 5*1-11

= -6

Again;

f(3) = 5*3-11

= 15-11

= 4

Therefore, f(1) = -6 and f(3) = 4.

The values of the trigonometric functions of t

[tex]$\sin t=-\frac{\sqrt{3} }{2}[/tex]

[tex]\cos t=\frac{1}{2},[/tex]

[tex]\tan t=-\sqrt{3}[/tex]

[tex]$\csc t-\frac{2}{\sqrt{3} }[/tex]

[tex]\sec t=2[/tex]

[tex]\cot t=\frac{1}{\sqrt{3} }[/tex]

Step-by-step explanation:

Given:

[tex]\sec(t)=2[/tex]

The terminal point of [tex]t[/tex] is in Quadrant [tex]IV[/tex]

Step 1:  

To find the values of trigonometric functions of t

[tex]\sec(t)=\frac{H}{A}[/tex]

[tex]=\frac{2}{1}[/tex]

Analyze the figure and find the value of O

[tex]t[/tex] ∈ [tex]IV[/tex]

[tex]O=\sqrt{2^{2}-1^{2} }[/tex]

[tex]=\sqrt{4-1}[/tex]

[tex]=\sqrt{3}[/tex]

Step 2:

[tex]$\sin t=-\frac{O}{H}[/tex]

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

[tex]\cos t=\frac{A}{H}[/tex]

[tex]=\frac{1}{2}[/tex]

[tex]\tan t=-\frac{O}{A}[/tex]

[tex]=-\sqrt{3}[/tex]

[tex]$\csc t=-\frac{H}{O}[/tex]

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

[tex]\sec t=\frac{H}{A}[/tex]

[tex]=\frac{2}{1}[/tex]

[tex]\cot t=-\frac{A}{O}[/tex]

[tex]=\frac{1}{\sqrt{3} }[/tex]

y = -x - 5

Step-by-step explanation:

y = mx + b

slope = m = -1

y = -1x + b

y = -x + b

Plug in (-7, 2) for x and y, and solve for b.

2 = -(-7) + b

2 = 7 + b

Answer:

Step-by-step explanation:

Rotation 180° is the transformation ...

  (x, y) ⇒ (-x, -y)

Dilation by a factor of 3 is the transformation ...

  (x, y) ⇒ (3x, 3y)

The two transformations together can be described by ...

  (x, y) ⇒ (-3x, -3y)

That is, the coordinates of A, B, C are each multiplied by -3. The image vertices are ...

  A' = -3A = A'(0, 0) . . . . . . . . the center of rotation and dilation is invariant

  B' = -3B = B'(-6, -18)

  C' = -3C = C'(0, -12)

Any dilated figure will not be congruent to the original. The triangles are similar.
