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

Answer:

k = 20

Step-by-step explanation:

simplify both sides of the equation, then isolate the variable.

hope it helps you!:))

Answer:

7

Step-by-step explanation:

f(x) = 2x2 – 1 and g(x) = x + 3,

f(g(-5))

First find g(-5)

g(-5) = -5 + 3

g(-5) = -2

Then substitute into f(x)

f(-2) = 2 ( -2) ^2 -1

      = 2 ( 4) -1

      = 8-1

     = 7

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.

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:

(m+ni)2=  -16 - 30i

2m + 2ni = -16-30i

.)2m=-16            .)2n=-30

m= -8                   n= -15

por lo tanto.....

m2 + n2

(-8)2 + (-15)2

-16 + (- 30 )

-16 - 30

Answer:

34

Step-by-step explanation:

Given

(- 3 - 5i)(- 3 + 5i) ← expand using FOIL

= 9 - 15i + 15i - 25i² [ i² = - 1 ]

= 9 + 25

= 34

.95 as a fraction would be 95/100

In simplest form this would be 19/20

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

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:

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:

No solution.

Step-by-step explanation:

[tex]5x+6= 5(x+1)-2\\5x+6=5x+3\\5x=5x-3\\0=-3[/tex]

Since 0=-3 is not valid, the equation doesn't have a solution.

Step-by-step explanation:

multiply 26 x 9

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:

>

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

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: the first one is when you multiply it, the second is where you divide it

Step-by-step explanation:

Because they are different equations that are similar but one just uses multiplication and the other uses division.

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.
