We are given the following the following inequality:

|x - 5| >= 1

When we have a inequality in the format:

|f(x)| >= a

There are two possible solutions.

Either f(x) <= -a or f(x) >= a

In this question:

|x - 5| >= 1

x - 5 <= -1

x <= -1 + 5

x <= 4

Or

x - 5 >= 1

x >= 1 + 5

x >= 6

In interval notation, the answer is:

The solution on the number line is:

The given matrix equation is:

To get the required equations, we will have to carry out the matrix multiplication, thus we have:

Hence, the correct option is option D

The question provides the following information;

Money at hand = 73.50

Money earned = x

Purchases made = 99.99

Money left over = 23.51

These sets of numbers can be put into an equation as shown below;

(73.5 + x) - 99.99 = 23.51

This equation means what you had at the beginning plus what earned from mowing lawns is a total of 73.5 + x. Subtract the cost of shoes purchased from this total and you'll now have a balance of 23.51

We can now solve for the money earned from mowing lawns as follows;

(73.5 + x) - 99.99 = 23.51

Add 99.99 to both sides of the equation (in order to isolate the 73.5 + x on the left side of the equation). You now have;

73.5 + x = 123.5

Next you subtract 73.5 from both sides of the equation (in order to isolate the x on the left hand side)

x = 50

This means the money earned from mowing lawns is $50

1. At age 65 when you retire, you have (future value) $202,531.69 from the IRA.

2. The total interest earned on the monthly investment of $95 at 6.25% for 40 years is $156,931.69.

The future value, which represents the compounded value of the monthly investments, can be computed using the FV formula or an online finance calculator as follows:

Number of years = 40 (65 - 25)

N (# of periods) = 480 months (40 x 12)

I/Y (Interest per year) = 6.25%

PV (Present Value) = $0

PMT (Periodic Payment) = $95

Results:

Future Value (FV) = $202,531.69

Sum of all periodic payments = $45,600 ($95 x 480 months)

Total Interest = $156,931.69

Thus, the future value of the monthly investment is $202,531.69 with an interest of $156,931.69.

First, divide the figure into 3 different figures.

Find the area of each figure, and then add them:

A1 is a rectangle:

Area of a rectangle: Lenght x width

A1 = 8 x 5.3 = 42.4 in2

A2 is also a rectangle:

Lenght = 4

width = 8 - 5.3 = 2.7

A2 = 4 x 2.7 = 10.8 in2

A3 is a triangle:

Area of a triangle = (base x height) / 2

base = 2.7

Height = 8-4 = 4

A3= ( 2.7 x 4 ) / 2 = 5.4 in2

Total area = A1 + A2 + A3 = 42.4 + 10.8 + 5.4 = 58.6 in2

Remember that a function is a relation between two sets of numbers where the first set is called domain, and the second set is called range.

The main characteristic that defines a function is that a domain element can be associated with only one element of the range set. In other words, one input value cannot have two different output values.

Therefore, the right answer is the third choice

Because this represents a function and its inverse also represents a function, that is, it's inverse have the characteristic of a function. The following set represents the inverse

As you can observe, this inverse set also follows the function definition, because every single input is associated with only one output.

The final price of gas per gallon after number of reduction and increment is $12.74.

Given,

The price of gas at store = 4.29 per gallon

The increased amount of gas = 0.55

The new price of gas = 4.29 + 0.55 = 4.84 per gallon

Then decreased 0.25. So, the price of gas = 4.84 - 0.25 = 4.59 per gallon

Again the price increases 8.30 and the new price become, 4.59 + 8.30 = 12.89 per gallon

Then, the price of gas finally went down to .15.

Therefore, the price of gas now is:

12.89 - 0.15 = 12.74

The sum of the sequence = -30072

Explanation

We are given a sequence of numbers and asked to find the sum of the terms up until the last term given. The sequence given is

9, 4, -1,.............., -546

On careful observation of this sequence, we can see that it is an arithmetic progression with a common difference of -5 between consecutive terms.

Common difference = (n + 1)th term - nth term

= 4 - 9 Or -1 - 4

= -5

For an arithmetic progression, the formula for the last term is given as

Last term = a + (n - 1)d

where

L = last term = -546

a = first term = 9

n = number of terms in the sequence = ?

d = common difference = -5

So, we can solve for the number of terms

-546 = 9 + (n - 1)(-5)

-546 = 9 - 5n + 5

-546 = 14 - 5n

14 - 5n = -546

-5n = -546 - 14

-5n = -560

Divide both sides by -5

(-5n/-5) = (-560/-5)

n = 112

We can now use the formula for the sum of an arithmetic progression to find the sum of this sequence.

We know all of these parameters now

Sum of this AP = (112/2) [(2 × 9) + (112 - 1)(-5)]

= 56 [18 + (111 × -5)]

= 56 [18 - 555]
