Which of the following is the graph of the inverse of f(x)=2x-3
Answer:
(-3,0) (0,1.5
Step-by-step explanation:
The answer choice which is the graph of the inverse of f(x)=2x-3 is; the graph of; f(x) = x/2 + 1.5.
What is the graph of the inverse of f(x)=2x-3?It follows from the task content that the function given is; f(x)=2x-3.
Hence, to find the inverse function;
y = 2x - 3x = y/2 + 1.5.Interchange the variables;
y = x/2 + 1.5.On this note, it follows that the inverse function is;
f(x) = x/2 + 1.5The graph of the inverse function therefore has points; (0, 1.5) and (2, 2.5) as points on the graph.

Answer:
I can see how this is confusing, because of -2, but the slope is decreasing, so the question wouldn't say:
[tex]-3/5x - -2[/tex]
This happens to turn the -2 into a regular 2 with an addition (+) sign.
and since the graph has an input of 5 but an output of -3, the equation would be:
y = -3/5x + 2

Number 2: (look at pivture) 10 point
Answer:
A
Step-by-step explanation:
Because the arrow is going 2 in the right direction...so you have to have the 2 in the equation...
and the reason it equals 5 instead of a (-) number is because of the KCC rule
so basically the equation is 2+3
or if you don't want the long way just look at all of the equations...only one of the have a 2 in it so it is automatically the correct answer
Answer:
I think it should be A.
Step-by-step explanation:
The first arrow represents 2, and the second arrow represents subtracting -3 from it, represented as -(-3). This means that the first part of the equation is 2 - (-3). Now you have to solve it. When subtraction is modeled like this with a negative number, it actually means addition. This means that the answer should be as simple as 2+3 because there were two negative signs. 2+3=5, so A should be the answer.

Robert uses a wheelbarrow to haul wood from his backyard to the back of his neighbor's house, located 9 kilometers away.
1. If he takes 2 breaks evenly when pushing the wheelbarrow the complete distance, at what distance does he take his first break?
2. Robert has 36 pieces to take, but can only take 9 each time. What distance in meters, will he have to travel to move all the wood.
Answer:
1. 3 breaks
2. 36,000 meters
Step-by-step explanation:
1. To solve this, we must divide 9 by 3 since the first break, the second break, and the complete distance are all major stops.
9 ÷ 3 = 3
Robert takes 3 breaks.
2. Since Robert has to has to take 36 pieces, but only 9 each time, we must divide 36 by 9.
36 ÷ 9 = 4
He will need to take 4 trips to take all the wood.
However, this question asks the distance in meters. Since 1 kilometer is 1,000 meters, then 9 kilometers is 9,000 meters.
9000 x 4 = 36000 meters

Megan and Desmond each added the same amount of water to their aquariums. Megan mixed 5 mL of a chemical solution with every gallon of water for her aquarium. Desmond mixed 8 mL of the chemical solution with every 2 gallons of water for his aquarium.
Which of these statements is true?
Answer:
i think it is the second one
Step-by-step explanation:
The statement "Megan added more chemical solution to her aquarium than Desmond did" is true.
What is Unit of Measurement?A unit of measurement is a definite magnitude of a quantity, defined and adopted by convention or by law, that is used as a standard for measurement of the same kind of quantity.
To compare the amount of chemical solution used by Megan and Desmond, we need to convert their rates to a common unit.
Let's convert Megan's rate to mL per 2 gallons by using proportions:
5 mL / 1 gallon = x mL / 2 gallons
Multiplying both sides by 2, we get:
10 mL = x
So Megan added 10 mL of chemical solution per 2 gallons of water.
Desmond's rate is already given as 8 mL per 2 gallons of water, so we can compare their rates directly.
Since 10 mL is greater than 8 mL, Megan added more chemical solution to her aquarium than Desmond did.
Therefore, the statement "Megan added more chemical solution to her aquarium than Desmond did" is true.

Dan charges a fixed amount per hour. He charges £180 for a job which takes 12 hours. Work how much he will charges for a job which will take 18 hours.
Answer:
270 pounds
Step-by-step explanation:
half of 12 is 6, so 18. Then you take half of 180 and add to 180
Answer:
18 hours = £270
Step-by-step explanation:
Find how much he charges per hour. Divide:
[tex]\frac{180}{12}=15[/tex]
So ha charges about 15 an hour. Multiply this price by the number of hours:
[tex]15*18=270[/tex]
Therefore, he will charge £270 for a job that takes 18 hours.
OR
Set a proportional relationship since he charges a fixed amount:
[tex]\frac{price}{time}=\frac{price}{time}[/tex]
Insert the appropriate corresponding values:
[tex]\frac{180}{12} =\frac{x}{18}[/tex]
Solve for the price after 18 hours of work, represented by x. Cross multiply:
[tex]12(x)=180(18)\\\\12x=3240[/tex]
Solve for x. Use inverse operations to isolate the variable. Divide both sides by 12:
[tex]\frac{12x}{12} =\frac{3240}{12} \\\\x=270[/tex]
Therefore, after 18 hours, he will charge £270.
