Answer:

1

Step-by-step explanation:

Since the value of x is 4 ( because four is in the position of x) you would plug in 4 into he equation.

2(4) = 8

Then 8 - 7 = 1

F(4) is 1

Therefore, your final answer is 1.

Substitute each given value of the variable to find which, if any, is a solution of inequality.
OlgaM077 [116]

Given:

The inequalities are:

a) w

b) t>-25, t=-24, -25, -25.1, -27

To find:

The solution of inequalities by substituting the given values.

Solution:

a) We have,

w

After substituting the given values one by one, we get

-4.3 False statement.

-5.3 False statement.

-8.3 True statement.

-9 True statement.

Therefore the solutions of w are w=-8.3, -9.

b)

We have,

t>-25, t=-24, -25, -25.1, -27

After substituting the given values one by one, we get

-24>-25 True statement.

-25>-25 False statement.

-25.1>-25 False statement.

-27>-25 False statement.

Therefore, the solution of t>-25 is t=-24.
