What is the slope of the line passing through the points A and B, as shown on the graph below?
A)-3
B) -1/3
C) 1/3
D) 3
Answer:
-1/3
Step-by-step explanation:
We can start by finding the coordinates of 2 points, A and B. A is (-3, 8) and B is (3, 6). Now, we can use [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex] to find the slope, and if you plug in those points you get (8 - 6)/(-3 - 3) = 2/(-6) = -1/3.

An item that originally cost $100 is decreased by 8%. The reduced price is then increased by 8%.
The resulting price is_
between $92 and $100
$92
$100
more than $100
Answer:
$99.36
Step-by-step explanation:
Hii!
So first, you need to find 8% of $100. You can do that by 100 x 0.08 which is $8. This means that the cost is reduced by $8 so 100 - 8 = $92
The reduced price is $92.
Then if we increase the reduced price by 8%, we will find the resulting price. Agani we find 8% of $92 which is 0.08 x 92 = 7.36. This means we have to increase the cost of $92 by this amount. $92 + 7.36 = $99.36
Hope this helps :)
Answer: 99.36
Step-by-step explanation:
because when you add 430 to 0 it makes 492/5 x 40 then x goes into m 4302 times there for its 99.36 USD.

..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]
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

Answer:
18 cm²
Step-by-step explanation:
All sides of a rhombus are the same length (as shown by the markings), so one side is 1/4 of the perimeter:
(24 cm)/4 = 6 cm . . . . side length
As with all parallelograms, the area is the product of the side length and the height perpendicular to that side:
A = (6 cm)(3 cm) = 18 cm²
It has an area of 18 cm².
I'm in need of help please
Answer:
1. x+ 2/3= -1/4
x+ 8/12= -3/12
-8/12 -8/12
x= -11/12
2. 1/4x+ 2/5= 1/3
1/4x+ 6/15= 5/15
-6/15 -6/15
1/4x= -1/15
15/60x= -4/60
÷15/60. ÷15/60
x= -4/15
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

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]
