Answer:

There are generally 3 methods to solve inequalities

Step-by-step explanation:

By algebraic method

Example 1: Solve: 2x - 7 < x - 5

2x - x < 7 - 5

x < 2

By the number-line method.

Example 2. Solve  

f

(

x

)

=

x

2

+

2

x

−

3

<

0

First, solve f(x) = 0. There are 2 real roots x1 = 1, and x2 = - 3.

Replace x = 0 into f(x). We find f(0) = - 3 < 0. Therefor, the origin O is located inside the solution set.

Answer by interval: (- 3, 1)

--------------------- - 3 ++++++++ 0 ++++ 1 ----------------

3.By graphing method.

Example 2. Solve:  

f

)

.

The graph of f(x) is an upward parabola (a > 0), that intersects the x-axis at x1 = 1 and x2 = - 3. Inside the interval (-3, 1), the parabola stays below the x-axis --> f(x) < 0.

Therefor, the solution set is the open interval (-3, 1)

Answer: f(-3) = 81

Step-by-step explanation:

f(-3) = 9(-3^2)

f(-3) = 9(9)

f(-3) = 81

Answer:

f(- 3) = 81

Step-by-step explanation:

Substitute x = - 3 into f(x) , that is

f(- 3) = 9(- 3)² = 9(9) = 81

A sequence is the pattern or rule that guides the creation of a set. The most common sequence are the arithmetic and the geometric sequence.

The complete question illustrates that we build a sequence of number.

Let the n term of the sequence be [tex]T_n[/tex].

2 times 3 less than the previous number means:

[tex]T_n = T_{n-1} - 2 \times 3[/tex]

Where:

[tex]T_n \to[/tex] The current number

[tex]T_{n-1} \to[/tex] The previous number

Assume the first number starts with 0, the next numbers will be:

[tex]T_2 = 0 - 2 \times 3 = -6[/tex]

[tex]T_3 = -6 - 2 \times 3 = -12[/tex]

[tex]T_4 = -12 - 2 \times 3 = -18[/tex]

So, the sequence is:

0, -6, -12, -18.....

Assume the first number starts with 3, the next numbers will be:

[tex]T_2 = 3 - 2 \times 3 = -3[/tex]

[tex]T_3 = -3 - 2 \times 3 = -9[/tex]

[tex]T_4 = -9 - 2 \times 3 = -15[/tex]

So, the sequence is:

3, -3, -9, -15.....

Answer:

$20.81

Step-by-step explanation:

There are 52 weeks in a year.

Let's say you get paid x dollars per hour. Every week, you get paid x dollars for each hour you work. If you work 44 hours, you get paid x * 44 dollars a week. We get paid x * 44 dollars each week for a year, for 52 weeks. We can represent this as (x*44) * 52 = x * 2288. This is the amount you get paid each year. Setting that to your yearly salary of $47,603, we have

$47603 = x * 2288

divide both sides by 2288 to isolate x

x ≈ $20.81

The expression for the total number of blocks is b³

This question seems to be incomplete. Here is the complete question :

A toy manufacturer produces a set of blocks that can be used by children to build play structures. The product packaging team is analyzing different arrangements for packaging their blocks. One idea they have is to arrange the blocks in the shape of a cube, with b blocks along one edge.

Write an expression representing the total number of blocks packaged in a cube measuring b blocks on one edge.

A cube is a 3-dimensional object that has six faces.

Characteristics of a cube

Volume of a cube = a³

Where a = length of a side

The expression that would be given is the volume of a cube. Since the length of the edge is b, the expression would be b³

Answer:

4085

Step-by-step explanation:

4 meters = 4000 millimeters + 85

= 4085

Answer:

By changing 4 meters 85 millimetres to milimetres we get 4085 milimetres

Step-by-step explanation:

In the first step change 4m to mm

We know that 1m = 1000mm

So, 4m = 4000mm

Now add 4000mm to 85mm

= 4000mm+85mm

= 4085mm
