The functions u and w are defined as follows.
u(x) = 2x+2
w(x) = – 2x² +2
Find the value of w (u(2)).

Answers

Answer 1

Answer:

w(u(2)) = -70

Step-by-step explanation:

u(x) = 2x + 2

w(x) = -2[tex]x^{2}[/tex] + 2

w ( u (2) )

Find u(2), substitute in 2 for x in the function u.

u(2) = 2(2) + 2

= 4 + 2

= 6

w(u(2))

= w(6)

Now subsitute in 6 for x, in the function w.

w(6) = -2[tex](6)^{2}[/tex] + 2

= -2 * 36 + 2

= -72 + 2

= -70

w(6) = -70

w(u(2)) = -70

Answers

Answer: I subtracted 8 from both sides then divided 3 on both sides

Step-by-step explanation: welcome

Answer:

Simplifying

3x + 8 = 26

Reorder the terms:

8 + 3x = 26

Solving

8 + 3x = 26

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-8' to each side of the equation.

8 + -8 + 3x = 26 + -8

Combine like terms: 8 + -8 = 0

0 + 3x = 26 + -8

3x = 26 + -8

Combine like terms: 26 + -8 = 18

3x = 18

Divide each side by '3'.

x = 6

Simplifying

x = 6

write the equation. the output of a function is 6 more than 2 times the input.

Answers

Answer:

y = 2x+6

Step-by-step explanation:

Let the output value be y

Let the input value be x

the output of a function is 6 more than 2 times the input

2 times the input is expressed as 2x

6 more than 2 times the input is expressed as 2x + 6

Since the output of a function is 6 more than 2 times the input, we will equate y to the resulting equation to have;

y = 2x + 6

Hence the required equation is y = 2x+6

What is the value of n in the equation below 9n-24=4n+6

Answers

Answer:

n = 6

Step-by-step explanation:

9n - 24 = 4n + 6              {Subtract 4n from both sides }

9n - 24 -4n = 6

       5n - 24 = 6               {Add 24 to both sides}  

               5n = 6 + 24

               5n = 30

                 n = 30/5

n = 6

Answer:

n=6

Step-by-step explanation:

Simplifying

9n + -24 = 4n + 6

Reorder the terms:

-24 + 9n = 4n + 6

Reorder the terms:

-24 + 9n = 6 + 4n

Solving

-24 + 9n = 6 + 4n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-4n' to each side of the equation.

-24 + 9n + -4n = 6 + 4n + -4n

Combine like terms: 9n + -4n = 5n

-24 + 5n = 6 + 4n + -4n

Combine like terms: 4n + -4n = 0

-24 + 5n = 6 + 0

-24 + 5n = 6

Add '24' to each side of the equation.

-24 + 24 + 5n = 6 + 24

Combine like terms: -24 + 24 = 0

0 + 5n = 6 + 24

5n = 6 + 24

Combine like terms: 6 + 24 = 30

5n = 30

Divide each side by '5'.

n = 6

Simplifying

n = 6
