3m+6-2m=-22. Solve or explain

Answer:

Here we have the domain:

D = 0 < x < 1

And we want to find the range in that domain for:

1) y = f(x) = x

First, if the function is only increasing in the domain (like in this case) the minimum value in the range will match with the minimum in the domain (and the same for the maximums)

f(0) = 0 is the minimum in the range.

f(1) = 1 is the maximum in the range.

The range is:

0 < y < 1.

2) y = f(x) = 1/x.

In this case the function is strictly decreasing in the domain, then the minimum in the domain coincides with the maximum in the range, and the maximum in the domain coincides with the minimum in the range.

f(0) = 1/0 ---> ∞

f(1) = 1/1

Then the range is:

1 < x.

Notice that we do not have an upper bound.

3) y = f(x) = x^2

This function is strictly increasing, then:

f(0) = 0^2 = 0

f(1) = 1^2 = 1

the range is:

0 < y < 1

4) y = f(x) = x^3

This function is strictly increasing in the interval, then:

f(0) = 0^3 = 0

f(1) = 1^3 = 1

the range is:

0 < y < 1.

5) y = f(x) = √x

This function is well defined in the positive reals, and is strictly increasing in our domain, then:

f(0) = √0 = 0

f(1) = √1 =1

The range is:

0 < y < 1

Answer:

328 metros

Step-by-step explanation:

Aquí, estamos interesados ​​en colocar un bucle alrededor de un campo de fútbol de la escuela de manera que sea imposible que alguien pueda acceder al campo.

Matemáticamente, la longitud de este bucle sería igual al perímetro del campo.

El perímetro del campo rectangular se puede calcular usando la fórmula; 2 (L + B)

En este caso tenemos; P = 2 (100 + 64)

P = 2 (164)

P = 328 metros La longitud del bucle es de 328 metros.

Answer:

Subtract 3z from each side

Step-by-step explanation:

9z+3=3z+15

Subtract 3z from each side

9z-3z+3=3z-3z+15

6z +3 = 15

Subtract 3 from each side

6z+3-3 = 15-3

6z = 12

Divide by 6

6z/6 = 12/6

z=2

Answer:

9z-3z+3=15

Step-by-step explanation:

move variable to the left hand side

4x + 57 = -133

Subtract 57 from both sides.

4x = -190

Divide each side by 4

x = -47.5

answer

-47.5

steps

-133 - 57 = -190

-190 divided by 4 = -47.5

Answer:

  34°

Step-by-step explanation:

If we assume that the acute angles in the triangle are 2x and (x+6), then we have ...

  2x +(x +6) = 90

  3x +6 = 90 . . . . . . simplify

  x + 2 = 30 . . . . . . . divide by 3

  x = 28 . . . . . . . . . . subtract 2

Then the angles are ...

  2x = 2(28) = 56

  x+6 = 28+6 = 34

The smallest angle is 34°.

Answer:

n=2

Step-by-step explanation:

4(5n-7)=10+2

1) First, distribute (multiply out 4)

20n-28=10+2

2) Combine like terms (add 10 and 2)

20n-28=12

3) Isolate the variable (Add 28 to 12)

20n=40

4) Isolate the variable (Divide by 20)

n=2

Answer:

x = -4

Step-by-step explanation:

Plug in -15 into the equation:

f(x) = 2x - 7

-15 = 2x - 7

Solve for x:

-15 = 2x - 7

-8 = 2x

-4 = x

Step-by-step explanation:

Pretty self explanatory but if you pop it in your calculator the left is greater.

Sqrt(2) + 3 = 4.4

Sqrt(7) - 3 = -0.35

The correct answer is,

Sqrt(2) + 3 > sqrt(7) - 3

Answer:

no solution

Step-by-step explanation:

[tex]-2 ( x + 3) = -2 (x + 1) -4 \\-2x + 3 = -2x -2 -4\\-2x + 3 = -2x - 6[/tex]

add [tex]2x[/tex] to both sides

[tex]-2x + 3 + 2x = -2x - 6 + 2x \\3 = -6[/tex]

That's impossible

so the equation no solution

Answer:

All real numbers ( -∞ ,∞)

Step-by-step explanation:

          Simplify [tex]-2(x+3)[/tex]

          Apply the distributive property.

[tex]-2x-6=-2(x+1)-4[/tex]

          Simplify  

[tex]-2(x+1)-4[/tex]

[tex]-2x-6=-2x -6[/tex]

          Move all terms containing  x  to the left side of the equation.

          Add  2  x  to both sides of the equation.

[tex]-2x-6+2x=0[/tex]

          Combine the opposite terms in  

[tex]-2x-6+2x[/tex]

          add [tex]-2x[/tex] and [tex]2x[/tex]

[tex]0-6= -6[/tex]

[tex]-6= -6[/tex]

Since [tex]-6= -6[/tex] , the equation will always be true for any value of  x .  All real numbers

The result can be shown in multiple forms.

All real numbers

Answer:

y=13

Step-by-step explanation:

2(6)+1

=12+1

=13

Answer:

y=13

Step-by-step explanation:

by replacing x in the equation with 6 the equation becomes y=2(6)+1 this is just a simple equation that you use to get the answer. 2×6 is 12 and 12+1=13 so y=13.

Answer:the answer is D

Step-by-step explanation:

This is reasonable because  feet can be rounded to 9 feet and  feet can be rounded to 3 feet. Since 9 - 2(3) = 3, the plumber will have about 3 feet of rubber tubing left. its true make sure you read the answer to make sure bc they can mix them up LOL

Answer:

  D.  The parabola is translated down 2 units.

Step-by-step explanation:

Comparing the two functions f(x), we see that the second one has a constant of 1 where the first one has a constant of 3. That means every value produced by the second function will be 2 units less than the value produced by the first function.

  D.  The parabola is translated down 2 units.

Solution:

[tex]-0.5[/tex]

Steps:

[tex](4x - 1) - 3x = - (x + 2)[/tex]

Start with the left side and combine like terms

[tex]4x-1-3x=-(x+2)\\[/tex]

Combine [tex]4x[/tex] and [tex]-3x[/tex]. After doing this, you would have [tex]x[/tex] because 4-3 = 1

[tex]x-1 =-(x+2)[/tex]

Then, you can distribute the negative on the right side

[tex]-(x+2) = -(x)+-(2) = -x-2[/tex]

You would end up with

[tex]x-1=-x-2[/tex]

Add x to each side.

[tex]2x-1=-2[/tex]

Add 1 to each side

[tex]2x=-1[/tex]

Divide each side by 2 to simplify.

[tex]x=-1/2\\x = -0.5[/tex]
