Step-by-step explanation:

Let's solve your equation step-by-step.

−19=b−6

Step 1: Flip the equation.

b−6=−19

Step 2: Add 6 to both sides.

b−6+6=−19+6

b=−13

Answer:

the answer is b= -13

Step-by-step explanation:

-6-13=-19

Answer:

86-9 = 77

77/7 = 11

|r-5| = 11

r = -6, 16

Step-by-step explanation:

7|r-5|+9=86

7|r-5|=86-9

7|r-5|=77

|r-5|=11

r-5=11 or r-5 = -11

r = 16

or

r = -6

Hope this helps :)

Length of distance of arc = 2πr × (∅/360)

∅ = 1/60 × 360 = 6⁰

Length = 2 × 22/7 × 3960(6/60)

Length = 44/7 × 3960 × 1/10

Length = 44/7 × 396

Length = 2489.142 cm

Answer:

n = 2

Step-by-step explanation:

2n - 8 = -2 (-3n + 12) + 8

2n - 8 = -(-6n + 24) + 8

2n - 8 = 6n - 24 + 8

2n - 8 = 6n - 16

-4n = -8

Divide each side by 4

n = 2

Answer:

n = 2

Step-by-step explanation:

Hi there!

We are given -(8-2n)=8-2(12-3n), which is an equation containing variables, and we want to solve the equation for the variable, which is n.

To do that, we want to isolate n on one side

This equation needs to be solved by the order of operations (PEMDAS, or parentheses, exponents, multiplication, division, addition, subtraction).

First, working from left to right, open up the parentheses on the left side by multiplying both 8 and -2n by -1 (the negative sign in front of the parentheses indicates -1(8-2n), or (8)(-1) + (-1)(-2n))

-1*8=-8

-1*-2n=2n

-8+2n = 8-2(12-3n)

Now on the right, it seems like we should subtract 2 from 8, then multiply the result by (12-3n), but remember we still have parentheses to deal with.

So multiply both 12 and -3n by -2, then add the numbers together

12*-2=-24

-3n*-2=6n

-24+6n

Remember that we didn't do anything to 8, so the equation so far is:

-8+2n=8-24+6n

Now we can start to isolate n on one side (leave n by itself on one side)

Remember we're still working from left-right

So remove -8 from the left by adding it to both sides (-8+8=0)

-8+2n=8-24+6n

+8       +8

_______________________

0 + 2n=16-24+6n

Now we can subtract 24 from 16

0 + 2n = -8 + 6n

Now, we still have 6n on the right, and remember; we want to isolate n on one side.

So let's remove it from the right by subtracting 6n from both sides

0 + 2n = -8+6n

   -6n         -6n

_________________

    -4n = -8

Now we have the expressions containing variables on the left and the numbers on the right. However, remember we just want a singular n by itself, not -4n.

A singular n is also 1n, since 1 * any number = that number

So divide both sides by -4 to find what the value of 1n is

n = 2

Hope this helps!

Answer:

Below,...

Step-by-step explanation:

1) = 0.67 (0.25 + 0.42 = 0.67)

2) = 0.20 (0.04 + 0.16 = 0.20)

3) = 0.84 (0.50 + 0.34 = 0.84)

4) = 1.21 (0.92 + 0.29 = 1.21)

5) = 0.42 (0.70 - 0.28 = 0.42)

6) = 0.51 (0.64 - 0.13 - 0.51)

7) = 1.15 (1.40 - 0.25 = 1.15)

8) = 0.75 (1.68 - 0.93 = 0.75)

9) = 0.25 (0.10 + 0.15 = 0.25)

10) = 0.35 (0.80 - 0.45 = 0.35)

11) = 1.32 (0.60 + 0.72 = 1.32)

12) = 1.34 (1.70 - 0.36 = 1.34)

Answer:

(0,-1)

Step-by-step explanation:

x point is 6, and the translation is x - 6

6 - 6 = 0

x = 0

y point is 0 and translation is y - 1

0 - 1 = -1

y = -1

Coordinates are (0,-1)

If my answer is incorrect, pls correct me!

If you like my answer and explanation, mark me as brainliest!

-Chetan K

======================================================

Explanation:

The given translation rule will have us do two things (in either order)

The given point is P(6,0). So x = 6 and y = 0 here.

Since x = 6, we then have x-6 turn into x - 6 = 6-6 = 0

Because y = 0, we have y-1 turn into y-1 = 0-1 = -1

So that's how (6,0) moves to (0,-1)

-----------------

Or you could write out the steps like this

[tex](x,y) \to (x-6,y-1)\\\\(6,0) \to (6-6,0-1)\\\\(6,0) \to (0,-1)\\\\[/tex]

The diagram below shows that we've moved 6 units to the left and 1 unit down.

Coordinate geometry is the use of a 2D plane to represent points.

Given that:

[tex]A = (-5,5) \to A' = (5,5)[/tex]

[tex]B = (-2,2) \to B' = (2, 2)[/tex]

[tex]C = (-3,2) \to C' = (2,3)[/tex]

By observing the pattern of transformation, the rule is:

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

Hence, the transformation is a rotation of 270 degrees clockwise

The length is calculated using the following distance formula:

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

So, we have:

[tex]AB = \sqrt{(-5 - -2)^2 + (5 - 2)^2} =\sqrt{18[/tex]

[tex]BC = \sqrt{(-2 - -3)^2 + (2 - 2)^2} =1[/tex]

[tex]AC = \sqrt{(-5 - -3)^2 + (5 - 2)^2} =\sqrt{13[/tex]

And

[tex]A'B' = \sqrt{(5 -2)^2 + (5 - 2)^2} =\sqrt{18[/tex]

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

[tex]A'C' = \sqrt{(5 - 2)^2 + (5 - 3)^2} =\sqrt{13[/tex]

By comparing the lengths of the image and the preimage, we can conclude that the transformation preserves length.

The measure of the angles is calculated as follows:

[tex]a^2 = b^2 + c^2 -2ab \cos A[/tex]

So, we have:

[tex]18 = 1 + 13 -2 \times 1 \times \sqrt{13} \cos C[/tex]

[tex]18 - 1 - 13= -2 \times 1 \times \sqrt{13} \cos C[/tex]

[tex]4= -2 \times 1 \times \sqrt{13} \cos C[/tex]

[tex]-2= \sqrt{13} \cos C[/tex]

Make cos C the subject

[tex]\cos C = -0.5547[/tex]

[tex]C = cos^{-1}(-0.5547)[/tex]

[tex]C = 124^o[/tex]

Also, we have:

[tex]\frac{a}{\sin A} =\frac{c}{\sin C}[/tex]

So, we have:

[tex]\frac{1}{\sin A} =\frac{\sqrt{18}}{\sin( 124)}[/tex]

[tex]\frac{1}{\sin A} =5.1175[/tex]

Rewrite as:

[tex]\sin A = \frac{1}{5.1175}[/tex]

[tex]\sin A = 0.1954[/tex]

[tex]A = \sin^{-1}(0.1954)[/tex]

[tex]A = 11^o[/tex]

Also, we have:

[tex]A + B + C = 180^o[/tex] --- sum of angles in a triangle

[tex]11 + B + 124 = 180^o[/tex]

Collect like terms

[tex]B = 180 -11 - 124[/tex]

[tex]B = 45[/tex]

Hence:

[tex]\angle A = 11[/tex]   [tex]\angle B = 45[/tex] and [tex]\angle C = 124[/tex]
