Inequalities are used to express unequal expressions.
The inequalities from the word problems are:
.
.
The statements from the inequalities are:
- -4 is not a solution to
- -6 is not a solution to
- -1 is not a solution to
- Graph b represents
<u>1. A number minus 3.5 is less than or equal to -2</u>
The statement can be broken down into the following expressions
So, when the expressions are brought together, we have:
<u>2. Zero is greater than or equal to twice a number x plus 1</u>
The statement can be broken down into the following expressions
So, when the expressions are brought together, we have:
<u />
<u>3. -1/2 is at least twice a number k minus 4</u>
The statement can be broken down into the following expressions
So, when the expressions are brought together, we have:
None of the options is correct
<h3>The solutions</h3><u>4. Tell whether -4 is a solution to x + 8 < -3</u>
We have:
Subtract 8 from both sides
The above inequality means that:
<em>x is less than -11</em>
-4 is not a solution, because -4 is greater than -11
<u>5. Tell whether -6 is a solution to 10 <= 3 - m</u>
We have:
Subtract 3 from both sides
Multiply both sides by -1 (the inequality sign changes)
Make m the subject
The above inequality means that:
<em>m is less than -7</em>
-6 is not a solution, because -6 is greater than -7
<u>6. Tell whether -1 is a solution to -3x <= -12.5</u>
We have:
Divide both sides by -3 (the inequality sign changes)
The above inequality means that:
<em>x is greater than or equal to </em><em />
-1 is not a solution, because -1 is less than <em />
The inequality is given as:
The less than sign (>) means that:
- The graph would use an open circle
- The arrow must point to the right
Only graph b satisfies this condition
Hence, the graph of is graph b

Answer:
Option B- The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
Step-by-step explanation:
Given :
The function represents price charged per customer where x is the number of $5 increases they charge over a rate of $50 per person.
The function represents the number of customers expected for the day, where x is the number of $5 increases they charge over a rate of $50 per person.
To find : (p⋅c)(2) mean about the horse-drawn carriage tour company.
Solution :
(p.c) means we multiply the p(x) and c(x)
Substitute the value of x=2
The horse-drawn carriage tour company can expect to take in $5760.
The function represents price charged per customer.
For x=2
The charge per customer is $60.
Therefore, Option B is correct.
The horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.
First, we'll figure out how many animals there are in total by adding up the cats and the dogs. In this case, we have 33+33=66 total animals. Then we need to figure out what fraction of these 66 animals are dogs:
So half of the animals are dogs. To write that as a percent, we need the fraction to be over 100, so:
50% of the animals are dogs.
So half of the animals are dogs. To write that as a percent, we need the fraction to be over 100, so:
50% of the animals are dogs.
