What is the slope of the line that passes through the points (2, 8) and (-3, 14)?
Write your answer in simplest form.
The slope of the line that passes through the points (2, 8) and (-3, 14) is -6/5 in the simplest form.
Define Slope.A line's steepness may be determined by looking at its slope. Slope is computed mathematically as "rise over run" (change in y divided by change in x).
What are coordinate pairs?An ordered pair in mathematics is a set of two things. The order of the objects in the pair matters because, unless a = b, the ordered pair differs from the ordered pair. Ordered pairs are also known as 2-tuples, or 2-length sequences.
The slope of a line is given by the formula:
m = (y2 - y1) / (x2 - x1)
where (x1, y1) and (x2, y2) are two points on the line.
Plugging in the given points, we get:
m = (14 - 8) / (-3 - 2)
m = 6 / -5
m = -6/5
so the slope of the line that passes through the points (2, 8) and (-3, 14) is -6/5 in the simplest form.

I need the minimum interval on [-10,6]
The minimum of the function is at x = -10. The minimum on the interval [-10,6] is -2.67.
What is a function?
A function from a set X to a set Y allocates exactly one element of Y to each element of X. The set X is known as the function's domain, while the set Y is known as the function's codomain.
Given function is f(x) = ³√(x-9)
The graph of the given function increases with the increase of the value of x and decreases with the decrease of the value of x.
Thus the minimum value of f(x)on the interval [-10,6] is at x = -10
Putting x = -10 in the given function.
f(-10) = ³√(-10-9)
f(-10) = ³√(-19)
f(-10) = -2.668
f(-10) = -2.67 (rounded to 2 decimal places).

You buy 2 shirts and 3 pairs of pants for $50. Your friend buys 3 shirts and 1 pair of pants for $40. What is the cost of
each shirt? of each pair of pants?
Shirts = 10$ Pants = 10$
Step-by-step explanation:
50 / 5 = 10$
3/1 = 10$
In this system of simultaneous equations, the cost of each shirt (x) equals $5 and the cost of each pair of pants (y) is $25.
Explanation:This is a system of simultaneous equation problems in Mathematics. Let's denote the cost of one shirt as x and one pair of pants as y. Based on the problem information, you have these two equations:
1) 2x + 3y = 50
2) 3x + y = 40
To solve for x, you can multiply the second equation by three and subtract the first equation from it:
3*(3x + y) - (2x + 3y) = 50
After simplifying, you find that x (cost of each shirt) equals 5.
In order to find y (cost of each pair of pants), you can now substitute x = 5 into the second original equation: 3*5 + y = 40, which gives you y = $25, the cost of each pair of pants.

Therefore it is the second smallest number because it is greater than -0.32 but smaller than zero. 0 belongs in the middle because it has no value and is a neutral number. 0.49 is greater than 0 so it should go to the right of zero. 6/10 is the same thing as 0.6. 0.6 is the greatest number of all these numbers so it should be the farthest to the right from 0.Please let me know if this helped!!!

20 pairs of atletics shoes and 10 pair of casual shoes are 750. how much is each shoe
Each pair of athletic shoe cost $20 and each pair of athletic shoe cost $35, in the given arithmetic problem.
What is arithmetic?By doing addition, subtraction, multiplication, and division on numbers, arithmetic is defined as the study of numbers.
Let 20x be the cost of manufacturing 20 athletic shoes and 10y be the cost of manufacturing 10 casual shoes, then
20x + 10y = 750
10y = 750 - 20x
y = 75 -2x
Let 25x be the cost of manufacturing 25 athletic shoes and 20y be the cost of manufacturing 20 casual shoes, then
25x + 20y = 1200
20y = 1200 - 25x
y = 60 - 25x/20
y = 60 - 1.25x
Equalise the y terms
75 -2x = 60 - 1.25x
75 - 60 = -1.25x + 2x
15 = 0.75x
x = 15/ 0.75
x = 20
Substitute the value of x in y = 75 -2x
y = 75 -2(20)
y = 75 - 40
y = 35
Thus, each pair of athletic shoe cost $20 and each pair of athletic shoe cost $35.

Ix B
By=1.19(z) 1.003
C y = 1.19(1.03)"
D
y = 1.19(1.003)
The equation that models the future cost of gasoline, if the price increases by 0.3% per month, is option D: y = 1.19(1.003)
In this equation, y represents the cost of gasoline at a certain time (measured in months) in the future. The initial cost of gasoline is represented by 1.19 (since this is the base value we are starting with), and the increase in price over time is represented by (1.003)^z where z represents the number of months in the future.
The equation 1.19(1.003)^z to model the future cost of gasoline is correct, the base cost multiplied by a number representing an increase in the price each month (1.003) raised to the power of the number of month. Each time z increases by 1, the price increases by 0.3%
Therefore, increasing z by 1 increases the price of gasoline by 0.3%. If you want to calculate the price for a certain number of months in the future, you can plug in that number for z in the equation and calculate the result.
Answer:y=1.19(1.003)x
