Which of the following is a solution to this inequality?
y > 1/2x + 2
Answers
Answer:
We conclude that only (1, 4) satisfies the inequality.
Thus, (1, 4) is a solution to this inequality.
Hence, option A is correct.
Step-by-step explanation:
Given the inequality
y > 1/2x + 2
FOR (1, 4)
y > 1/2x + 2
substituting x = 1, and y = 4
4 > 1/2(1) + 2
4 > 1/2+2
4 > 5/2
TRUE!
Reason: It is true because 4 is indeed greater than 5/2
Thus, (1, 4) satisfies the inequality.
Therefore, (1, 4) is a solution to this inequality.
FOR (-1, 1)
y > 1/2x + 2
substituting x = -1, and y = 1
1 > 1/2(-1) + 2
1 > -1/2+2
1 > 3/2
FALSE!
Reason: It is false because 1 can not be greater than 3/2
Thus, (-1, 1) DOES NOT satisfy the inequality.
FOR (2, 3)
y > 1/2x + 2
substituting x = 2, and y = 3
3 > 1/2(2) +2
3 > 1+2
3 > 3
FALSE!
Reason: It is false because 3 can not be greater than 3.
Thus, (2, 3) DOES NOT satisfy the inequality.
FOR (0, 2)
y > 1/2x + 2
substituting x = 0, and y = 2
2 > 1/2(0) +2
2 > 0+2
2 > 2
FALSE!
Reason: It is false because 2 can not be greater than 2.
Thus, (0, 2) DOES NOT satisfy the inequality.
Therefore, we conclude that only (1, 4) satisfies the inequality.
Thus, (1, 4) is a solution to this inequality.
Hence, option A is correct.

150% of what number is 49?
Answers
Answer:
32 2/6
Step-by-step explanation:
150% of what number is 49
Can be written as;
1.5x = 49
( To find the percent of a number, one has to move the decimal back two spaces on the percent ( because a percent is out of 100), and then multiply by the number)
Use inverse operations to solve;
1.5x = 49
/1.5 /1.5
x = 32 2/3
There are 156 laptops and desktop computers in a lab. There are 8 more laptops than deskto
computers. What is the total number of desktops in the lab?
Answers
Answer:
It would be 70
Step-by-step explanation:
First step: Divide 156 by 2
156 / 2 = 78
Second Step: The half of 156 is 78. Now we have 78 laptops and desktops, and as we know the question says that "there are 8 more laptops than desktops", the next step to follow is to subtract 8 from 78 (Desktops) and add 8 to the 78 (Laptops).
78 - 8 = 70 Desktops
78 + 8 = 86 Laptops

A software CD can be manufactured for $0.10 each. The development cost to produce the CD is $500,000. The first 200 CDs were used by testers to test the functionality of the software and were not sold.
Write a function, f, for the average cost, in dollars, of a saleable software CD where x is the number of saleable software CDs.
Answers
Answer:
The function that represents the average cost in dollars of saleable software CD is given as follows;
f(x) = 500,020/x + 0.10
Step-by-step explanation:
The given parameters are;
The cost of manufacture of each software CD = $0.10
The development cost to produce the CD = $500,000
The number of CDs that are not sold = The first 200 CDs
The total cost of production. 'C', of the the CD is given as follows;
C = $500,000 + $0.10×200 = $500,020
The function, 'f' for the average cost in dollars of a saleable software CD where 'x' is the number of saleable software CDs is given as follows;
f(x) = (C + 0.10·x)/x = C/x + 0.10
∴ f(x) = 500,020/x + 0.10.

Polly's veterinarian told her a dog that weighs w kilograms needs 30w+70 calories each day to stay healthy. Polly's dog, Otis, weighs 22 kilograms. How many calories does Otis need each day to stay healthy?
Answers
Answer: 730 calories
Step-by-step explanation:
Since the function is given as: 30w+70 and Polly's dog, Otis, weighs 22 kilograms.
The amount of calories that Otis need each day to stay healthy will be:
= 30w + 70
= 30(22) + 70
= 660 + 70
= 730 calories

C) x = 2
D) x = 5.2
E) x = 6.5

A and D
Step-by-step explanation:
I could be wrong but the solutions are the points of intersection between the two functions. By looking at it. I can see that its about -3.3 and 5.2
Hope this helps!
The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.
What is a function?Function is a type of relation, or rule, that maps one input to specific single output.,Functions which repeats their values after a fixed interval, are called periodic function.
WE have been given the function x as
f (x) = g(x)
Therefore,
3(17x-6.5) = 108
Then Divide each side by 3;
3/3(17x-6.5) = -108/3
17x - 6.5 = -36
Add 6.5 to each side;
17x-6.5+6.5 = -36+6.5
17x = 42.5
Divide by 17;
17x/17 = -42.5/17
x = -3.3
The x-values are approximate solutions to the equation f (x) = g(x) that is -3.3 thus the correct option is A.
