If f(x) = 4x +5, find f(5).

Answers

Answer 1
Answer:

The value of the functionf(x) = 4x +5 at x = 5 is f(5) = 25

What is function?

"It is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output."

For given example,

Given function: f(x) = 4x +5

We need to find the value of f(x)

This means, we need to find the function f(x) when x = 5

Substitute x = 5 in the given function.

⇒ f(x) = 4x +5

⇒ f(5) = 4(5) +5

⇒ f(5) = 20 + 5

⇒ f(5) = 25

Therefore, f(5) = 25

Answer 2
Answer: F(5)=4x+5
F(5) is 0 at this point
Subtract 5 from both sides
-5=4x
Divide both sides by 4
-5/4=x
So f(5)=-5/4

Which equation can be used to represent six added to twice the sum of a number and four is equal to one-half of the difference of three and the number?

Answers

six added to twice the sum of a number and four is equal to one-half of the difference of thee and the number.

Let x be the number.

6 + 2(x + 4) = 1/2 * (3-x)

Find the value of x.

6 + 2x + 8 = 3/2 - x/2
2x + x/2 = 3/2 - 8 - 6
2x + x/2 = 3/2 - 14
2(2x + x/2) = 2(3/2 - 14)
4x + x = 3 - 28
5x = -25
x = -25/5
x = -5

To check: x = -5

6 + 2(x + 4) = 1/2 * (3-x)

6 + 2(-5+4) = 1/2 * (3 - (-5))
6 + 2 (-1) = 1/2 * (3 + 5)
6 - 2 = 1/2 (8)
4 = 4

Solve for x.
3(x + 5) - 2(x + 2) = 20

Answers

3(x + 5) - 2(x + 2) = 20

Distribute the 3 and -2.

3x + 15 -2x - 4 = 20

Simplify.

x + 11 = 20

Subtract 11 on both sides

x = 9

Your final answer is x = 9.
