**Answer 2**

Option B is the **correct** representation of the number line of the **inequality condition**.

What is linear inequality?

According to the **mathematical **definition of inequality, neither side is equal. When a relationship leads to a non-equal **comparison **between two **expressions **or numbers, it is known as an **inequality **in mathematics. The equal sign "=" in this statement can be replaced with any of the **inequality **symbols, such as greater than (>), **less **than (<), **greater **than or equal to (≥), **less **than or equal to (≤), or not **equal** to (≠).

Given **equation **

1/4 x + 1 < 5

**subtract **1 from both sides,

1/4 x + 1 - 1 < 5 - 1

1/4 x < 4

**multiply **both sides by 4,

1/4x * 4 < 5*4

x < 16

the graph should be **less **than 16 and in that 16 is not **included**.

Hence option B is **correct**.

### Answers

**Answer:**

x = 18

**Step-by-step explanation:**

We can use a proportion to solve for x.

30/x = 40/24

Cross-multiply

40x = 720

Divide by 40

x = 18

Check the answer

30/18 = 40/24

30 x 24 = 18 x 40

720 = 720

This means that we can be sure our answer is correct. If the answer didn't produce a true statement when substituted into the original proportion, we would know our answer was incorrect.

Nila uses the equation c=8h to figure out the total amount c she should charge a customer if she babysits for h hours.

Part A. Find the constant of proportionality and explain what it means.

Part B. Nila decides to increase the rate she charges customers by $2 per hour. What equation should she now use to determine how much to charge her customers? Explain.

PLS HELP!!!

### Answers

Answer:

c = 10h

Step-by-step explanation:

c = 8h

Where,

c = Total amount she should charge a customer

h = Number of hours

8 = amount charged per hour of babysitting

A. 8 is the constant of proportionality and it means Nila charges $8 per hour of babysitting

B. If she decides to increase the rate she charges customers by $2 per hour, then the new equation she should use to determine how much to charge her customers is:

c = (8 + 2)h

c = 10h

The population of wolves in a forest was 138 in 2000. The population is increasing at a rate of 5% per year. How many wolves will be in the forest in 10 years?

### Answers

**Answer:**

**207 wolves**

**Step-by-step explanation:**

**Given **

Initial population = 138

Rate = 5%

Time = 10years

First calculate the increment after 10 years

Increment = 138 * 5 * 10/100

Increment = 138 /2

Increment = 69

Number of wolves in 10years = 138 +69

**Number of wolves in 10years = 207wolves**

**Answer:**

f(x)=f(4)-[tex]2^{x-1}[/tex]

**Step-by-step explanation:**

The rate of change can be found out by dividing -8 by 4, 16 by -8, or -32 by 16.

The rate of change is -2

To find f(1), I will find the first value in the sequence, which is 4.

### Answers

**Answer: x = -1.4; y = -1.2**

**Step-by-step explanation:**

y = -2x - 4

y = 3x + 3

Substitute

3x + 3 = -2x - 4

Add 2x to both sides

5x + 3 = -4

Subtract 3 from both sides

5x = -7

Divide both sides by 5

x = -1.4

y = -2x - 4

Substitute -1.4 for x

y = -2 (-1.4) - 4

y = 2.8 - 4

y = -1.2

### Answers

Answer: See explanation

Step-by-step explanation:

To solve this, we have to calculate the lowest common multiple of 2 and 5. This will be:

Multiples of 2 = 2, 4, 6, 8, 10, 12, 14, 16, 18, 20 ....

Multiples of 5 = 5, 10, 15, 20 ....

This means that he will swim and bike every 10th day together. This will be on the 10th, and 20th in October.

Answer:

On the 10th!
