F(3) occurs when x =3. So lets plug 3 into our equation.

f(3) = -4(3)^2 + 4(3)-4\\f(3) = -4(9) + 12- 4\\f(3) = -36 + 12- 4\\f(3)= -28

F(3) = -28

I hope this helps! :)

The complete inequality is -2 < x < 35

<h3>How to determine the range of value of x?</h3>

The figure attached to the question is the given parameter

From the figure, we understand that:

Side length BA and side length BD are equal.

This is represented as:

BA = BD

Because the side length AC is less than the side length CD, then it means that:

The measure of the angle ABC is less than the measure of the angle CBD

This is represented as:

∠ABC < ∠CBD

Where

ABC = x + 2

and

CBD = 37

Substitute ABC = x + 2 and CBD = 37 in the inequality expression ∠ABC < ∠CBD

So, we have:

x + 2 < 37

Subtract 2 from both sides of the inequality

x + 2 - 2 < 37 - 2

Evaluate the differences

x < 35

From the question, we have the following incomplete inequality

-2 < x < [ ]

Complete the inequality as follows:

-2 < x < 35

Hence, the complete inequality is -2 < x < 35

There are 1,200 students at roosevelt middle school. There are 700 boys at the school. What percentage of the students at roosev
Scilla [17]

Answer:

x=175/3

Step-by-step explanation:

700/1200=x/100

Simplify to 7/12

7/12=x/100

Multiply both sides by 100

7/12×100=x

Simplify 7/12 ×100 to 700/12

700/12=x

Simplify 700/12 to 175/3

175/3=x

Switch Sides x=175/3

hope that helps you

Two opposite sides of a parallelogram measure 5n-11 and 2n +22. Find the length of
TiliK225 [7]

Answer:

Both sides are 44

Step-by-step explanation:

5n - 11 = 2n + 22

5n - 2n = 22 + 11

3n = 33

n = 11

First Side

5n - 11 = 5 (11) - 11 = 55-11 = 44

Second Side

2n + 22 = 2 (11) + 22 = 44
