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.

y=−2x−4
y=3x+3
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

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

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.

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

Write an explicit formula for the sequence 4,-8, 16,-32
Answers
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.
Apply these values to the explicit formula:
f(x)=f(1)[tex]r^{x-1}[/tex]
