The area of rectangle with length 3x + 2 and width 3x - 4 is 9x² - 6x - 8.
What is the area of rectangle?Once the length and width of a rectangle are known, the area is calculated. The area of a rectangle can be calculated by multiplying its length and width.
Here given that,
The rectangle's length is (3x + 2) units.
The width of the rectangle is (3x - 4).
We must determine the area of a rectangle.
Now,
Since the area of a rectangle equals length x width .
As a result, the area of a rectangle equals,
A = (3x + 2) (3x - 4)
By simplifying the expression we get,
= (3x)(3x) + (3x)(-4) + 2(3x) + 2(-4)
= 9x² - 12x + 6x - 8
= 9x² - 6x - 8
Therefore the area of rectangle will be 9x² - 6x - 8.

If the price of gasoline increased by 0.3% per month, which
equation models the future cost of gasoline?
X
Ay=1.19(z)1.03
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

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.

A continuous random variable is one that has a range of possible values. In other words, if a random variable adopts a value that fits within a specific range, it is said to be continuous.
Measurements like height, weight, and time are all represented by continuous random variables. A continuous random variable is represented as the area under a density curve. The concept of a continuous random variable, as well as its mean, variance, types, and related examples
P(X < 0.35) = 0.35
P(X = 0.35) = 0 since X is a continuous random variable and the probability of a specific value is 0.
P(0.35 < X < 1.25) = 1.25 - 0.35 = 0.9
P(0.10 < X < 0.20 or 0.6 < X < 0.9) = (0.20 - 0.10) + (0.9 - 0.6) = 0.3
P(X < 0.5 or X > 0.6) = (0.5 - 0) + (1 - 0.6) = 0.9

You roll a number cube and record an odd number 12 times in a row. As the number of times you roll an odd number increases, what happens to the theoretical probability that you roll an even number? (Please show step by step explanation)
When the number of times you roll an odd number increases, the theoretical probability that you roll an even number would decrease.
How is the probability of rolling an even number affected ?As the number of times you roll an odd number increases, the theoretical probability that you roll an even number decreases. This is because the probability of rolling an even number is inversely proportional to the number of times you roll an odd number.
If you are rolling a fair die, the probability of rolling an even number is 3/6 or 1/2, and the probability of rolling an odd number is also 3/6 or 1/2.
As the number of times you roll an odd number increases, the number of rolls that are left for an even number decreases, thus the probability of rolling an even number decreases as well.
For example, if you roll the die 10 times and 6 of them are odd numbers, the probability of rolling an even number in the remaining 4 rolls is 4/4 or 1 (100%) because you are guaranteed to roll an even number.

X^2+2xy-2y^2+x=2 find gradient at point (-4,1)
Therefore , the solution to the given problem of slope intercept comes out to be dy/dx = -1/2.
A slope-intercept form is precisely what?After you are certain if Y = mx + b, the gradient intercept approach can be employed. By using just one particular point on the line and its slope, the direction form is a way to represent an axiom for a line. The slope is defined as such rise across run and is represented first by point form (x,y), and may be calculated using the slope intercept method, y = mx + b. (0, b). By using just one specific statement on the vector and its slope, the direction form is a technique to write a linear model for a line.
Here,
Given : x² +2xy - 2y² +x =2
thus,
To find the gradient at point (-4,1) :
We have to find the dy/dx
so,
=> 2x + 2y + 2xdy/dx -2ydy/dx +1 =0
=> dy/dx (2x-2y) = -(2x+ 2y) -1
=>dy/dx = -(2x+2y) -1 / (2x-2y)
So , at the point (-4,1)
=> dy/dx = -(-8 + 2) -1 / (-8 -2)
=>dy/dx = 5/-10
=>dy/dx = -1/2
Therefore , the solution to the given problem of slope intercept comes out to be dy/dx = -1/2.

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)

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

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.
