Answer:

The answer is m = x + 2kn

Step-by-step explanation:

Rewrite the equation as  − 2 k n  +  m  =  x . Add  2 k n  to both sides of the equation.

Answer:

Kindly check explanation

Step-by-step explanation:

Given the equation:

s = 10│x - 4│+ 50

Where s = sound level in decibels

x = number of measures of music played

Step 1:

Subtract 50 from Both sides

s - 50 = 10│x - 4│+ 50 - 50

s - 50 = 10│x - 4│

For s = 80

80 - 50 = 10│x - 4│

30 = 10│x - 4│

Clear the absolute value sign

± 30 = 10x - 40

Hence ;

Lower value :

- 30 + 40 = 10x

10 = 10x

x = 1

Upper value :

+30 + 40 = 10x

70 = 10x

x = 7

Answer:

a = 60

60°, 60°, 120°, and 120°

Step-by-step explanation:

So we know that the sum of the angle measures of the quadrilateral is 360° and that the four angle measures are a, 2a, a, and 2a. This means that the sum of a, 2a, a, and 2a should equal 360.

a + 2a + a + 2a = 360

Combine like terms.

6a = 360

Divide both sides by 6.

a = 60

So the value of a would be 60.

Now to find the angle measures from least to greatest, we would have to find the values of a, 2a, a, and 2a.

a = 60

2a = 120

a = 60

2a = 120

So the angle measures from least to greatest is 60°, 60°, 120°, and 120°.

I hope you find my answer and explanation to be helpful. Happy studying.

Answer:

a=60 degrees

Step-by-step explanation:

Total angle measurements=360 so

2a+2a+a+a=360

2(60)+2(60)=240

240+60+60=360

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

So a=60

For the last one,it is -a^10b^5c^15

Step-by-step explanation:

When you raise monomials to a power, you multiply each thing inside the parenthases by the power you are raising it to. (-a^2bc^3)^5=(-a^5x3)(b^1x5)(c^3x5)=-a^10b^5c^15

Hope this Helps

Answer:  see below

Step-by-step explanation:

Step 1: Find the slope (m) using the formula:    [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

Step 2: Plug in the slope (m) and one of the points (x₁, y₁) into the Point-Slope formula.      y - y₁ = m(x - x₁)

1. (-2, 3) and (0, 2)

Step 1:  [tex]m=\dfrac{3-2}{-2-0}\quad =\dfrac{1}{-2}\quad =-\dfrac{1}{2}[/tex]

Step 2:  [tex]y-2=-\dfrac{1}{2}(x-0)[/tex]

             [tex]y-2=-\dfrac{1}{2}x[/tex]

                 [tex]\large\boxed{y=-\dfrac{1}{2}x+2}[/tex]

2. (2, 3) and (-3, 0)

Step 1:  [tex]m=\dfrac{3-0}{2-(-3)}\quad =\dfrac{3-0}{2+3}\quad =\dfrac{3}{5}[/tex]

Step 2:  [tex]y-0=\dfrac{3}{5}(x-(-3))[/tex]

                   [tex]y=\dfrac{3}{5}(x+3)[/tex]

                 [tex]\large\boxed{y=\dfrac{3}{5}x+\dfrac{9}{5}}[/tex]

3. (-4, 4) and (4, 5)

Step 1:  [tex]m=\dfrac{4-5}{-4-4}\quad =\dfrac{-1}{-8}\quad =\dfrac{1}{8}[/tex]

Step 2:  [tex]y-4=\dfrac{1}{8}(x-(-4))[/tex]

             [tex]y-4=\dfrac{1}{8}(x+4)[/tex]

             [tex]y-4=\dfrac{1}{8}x+\dfrac{1}{2}[/tex]

                 [tex]\large\boxed{y=\dfrac{1}{8}x+\dfrac{9}{2}}[/tex]

4. (5, 3) and (-1, 5)

Step 1:  [tex]m=\dfrac{3-5}{5-(-1)}\quad =\dfrac{3-5}{5+1}\quad =\dfrac{-2}{6}\quad =-\dfrac{1}{3}[/tex]

Step 2:  [tex]y-3=-\dfrac{1}{3}(x-5)[/tex]

             [tex]y-3=-\dfrac{1}{3}x+\dfrac{5}{3}[/tex]

                 [tex]\large\boxed{y=-\dfrac{1}{3}x+\dfrac{14}{3}}[/tex]

5. (-3, 3) and (0, -1)

Step 1:  [tex]m=\dfrac{3-(-1)}{-3-0}\quad =\dfrac{3+1}{-3-0}\quad =\dfrac{4}{-3}\quad =-\dfrac{4}{3}[/tex]

Step 2:  [tex]y-3=-\dfrac{4}{3}(x-(-3))[/tex]

             [tex]y-3=-\dfrac{4}{3}(x+3)[/tex]

Answer:

The translation is left 1 unit, up 5 units ⇒ A

Step-by-step explanation:

Let us revise the rules of translation of a function

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)  

If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)  

If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k  

If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

The vertex form of the quadratic function is f(x) = ax² + bx + c, where a, b, and c are constant is f(x) = a(x - h)² + k, where h =   and k = f(h)

You will use the vertex form to find the translation

∵ g(x) = x² + 2x + 6

∴ a = 1 and b = 2

→ use the rule of h to find it

∴ h =  

∴ h = -1

→ Use it to find k

∵ g(h) = k

∴ k = g(-1)

→ Substitute x by -1 in g to find k

∴ k = (-1)² + 2(-1) + 6 = 1 - 2 + 6

∴ k = 5

→ Substitute the values of h and k in the vertex form above

∴ g(x) = 1(x - -1)² + 5

∴ g(x) = (x + 1)² + 5

→ By using the 2nd and 3rd rules of translation above

∴ f(x) is translated 1 unit to the left and 5 units up

∴ The translation is left 1 unit, up 5 units

Answer:

it's A. left 1 unit

Answer:

I am divisible by 5.

So your ones digit is 0 or 5

I am an even number.

So your ones digit is 0.  We fill that in.

_ _ 0

My tens digit is 1.

So we fill that in.

_ 1 0

My tens digit is greater than my ones digit.

Well, of course 1 is greater than 0. We didn't need to be told that.

I have only one odd digit.

Since the 1 is odd, the hundreds digit is even, 2,4, or 8

I am less than 400.

So your hundreds digit is 2.  Fill that in and we're done.

2 1 0

My hundreds digit is greater than my tens digit.

Of course 2 is greater than 1, we didn't need to be told that.

I am divisible by 3.

Of course 210 is divisible by 3.  We didn't need to be told that.
