To rent a moving truck for the day it cost $33 +1 dollar for each mile driven.
Answer:
A) y=x+33 or 33+m (m = miles)
B)$333
Step-by-step explanation:
A is, y = the total cost, x = miles driven , 33 = cost for the day you rent it
B is, $1x$300 = $300 + $33 (base cost) = $333
Write an expression for the cost to rent the truck.
33 + x = y
You rive the truck 300 miles. How much do you pay?
33: initial rent fee
300: miles
One mile equals one dollar so the answer would be.
33 + 300 = 333

..A teacher is buying T-shirts for her algebra class.
- Long-sleeve T-shirts (x) cost $16 each.
- Short-sleeve T-shirts (y) cost $10 each.
The teacher wants to buy at least 24 T-shirts, and she wants to spend no more than $300 in all. Which system of inequalities represents this situation?
Answer:
[tex]240\leq 10x+16y\leq 300[/tex]
Step-by-step explanation:
Let short-sleeve be x and long-sleeve be y
So, the least amount she could spend buying at least 24 shirts is $240 because the cheapest shirt is $10/shirt. The max amount is already given.
[tex]240\leq 10x+16y\leq 300[/tex]

How can you multiply a letter
Answer:you can multiple a letter only by its self not other letters so you can do x times x which is 2x but you can’t do x times y.
Step-by-step explanation:
1.) I'm trying to see if I got this answer right. If not, correct me.
Step-by-step explanation:
The constant of proportionality (or constant of variation), denoted by "k," represents the constant proportion or ratio that exists between two variables, y and x, such that y = kx.
The given problem asks for you to identify the constant of proportionality and what it represents in context of the problem.
In the equation, y = 4.75x:
y = total cost in dollars earned
x = number of bracelets
The constant of proportionality, k = 4.75, represents the increase in total cost earned for every x number of bracelets sold. In other words, the total increases by 4.75 for every bracelet sold.
Thus, since Liv made x = 2 bracelets, then her total cost will equal to $9.50 because:
y = 4.75x
y = 4.75(2)
y = 9.50

Use the graph to determine the domain and range. Then state whether the relation is a function.
What is the domain of the function?
Answer:
[-2, 4]
Step-by-step explanation:
The domain of a function is the set of all x-values a relation could possibly take on to have an output. This is represented by in the graph by having the line correspond to the x-value. From the graph shown we can see that x-values from -2 to 4 have a line corresponding to them, and the dots are closed meaning it is inclusive. This would be written as: [-2, 4]
A car is traveling is at a speed of 99 km/h. what is the car speed in kilometers per minute how many kilometers for the car travel in 2 minutes do not round your answers.
