what divided by 6 equals 4
The correct answer is 1.5.
What is the formula of divide?The formula of divide is Dividend ÷ Divisor = Quotient + Remainder.
What is Remainder?Remainder is the left over number in the division.
Given:
6 ÷ ? = 4......(1)
Here we assume x is divided by 6 equals 4.
Then put x in given equation (1).
6 ÷ x = 4
x = 6 ÷ 4.
x = 6/4 = 1.5
Here 6 is dividend, 4 is divisor and 1.5 is quotient.

what are the two types of exponential functions?
The two types of exponential functions are:
Exponential Growth: exponential growth function is [tex]y = a^x[/tex], where "a" is the base and "x" is the exponent.
Exponential Decay: exponential decay function is [tex]y = a^{(-x)[/tex], where "a" is the base and "x" is the exponent.
The two types of exponential functions are:
Exponential Growth: In an exponential growth function, the base (often denoted by "a") is greater than 1.
As the input (x) increases, the output (y) grows at an increasing rate, creating a steep upward curve on the graph.
The general form of an exponential growth function is [tex]y = a^x[/tex], where "a" is the base and "x" is the exponent.
Exponential Decay: In an exponential decay function, the base (often denoted by "a") is between 0 and 1 (exclusive).
As the input (x) increases, the output (y) decreases at an increasing rate, creating a steep downward curve on the graph.
The general form of an exponential decay function is [tex]y = a^{(-x)[/tex], where "a" is the base and "x" is the exponent.
Both types of exponential functions show rapid growth or decay patterns, and their graphs exhibit a characteristic curve that is continuous and smooth.
The difference lies in the behavior of the output (y) concerning the input (x).
In exponential growth, the output increases exponentially with increasing input, while in exponential decay, the output decreases exponentially as the input increases.

A shopper purchased 8 T-shirts and 5 pairs of pants for $220. The next day he purchased 5 T-shirts and 1 pair of pants for $112. How much does each T-shirt and each pair of pants cost?
By setting up a system of linear equations based on the shopper's purchases and solving it, we found that the cost of each T-shirt is $20, and the cost of each pair of pants is $12.
Explanation:To find out how much each T-shirt and each pair of pants cost based on the shopper's purchases, we can set up a system of linear equations. Let's denote the cost of a T-shirt as T and the cost of a pair of pants as P.
The two purchases give us these equations:
8T + 5P = $220
5T + 1P = $112
Next, we use a method such as substitution or elimination to solve these simultaneous equations. If we multiply the second equation by 5, we get:
5(5T + 1P) = 5($112)
25T + 5P = $560
Now subtract the first equation from this result:
25T + 5P - (8T + 5P) = $560 - $220
17T = $340
T = $20
Now that we know the cost of a T-shirt, we can substitute T in one of the original equations to find P:
5T + P = $112
5($20) + P = $112
$100 + P = $112
P = $12
So, a T-shirt costs $20 and a pair of pants costs $12.

Which expression gives the distance between the points (2, 5) and (-4, 8)?
The expression for the distance between the points (2, 5) and (-4, 8) is the square root of 45 or 3√5, which is approximately 6.708.
Explanation:The expression that gives the distance between the points (2, 5) and (-4, 8) is found using the distance formula which is derived from the Pythagorean theorem. The formula is √((x2 - x1)² + (y2 - y1)²), where (x1, y1) and (x2, y2) are coordinates of the two points.
To find the distance between (2, 5) and (-4, 8), substitute x1=2, y1=5, x2=-4, and y2=8 into the formula:
√((-4 - 2)² + (8 - 5)²) = √((-6)² + (3)²) = √(36 + 9) = √45
The distance is therefore the square root of 45, which can be simplified to 3√5 (approximately 6.708).
Final answer:
The distance between the points (2, 5) and (-4, 8) is calculated using the distance formula, resulting in 3√(5) units.
Explanation:
The distance between the points (2, 5) and (-4, 8) can be calculated using the distance formula, which is derived from the Pythagorean theorem. The distance formula is √((x2 - x1)² + (y2 - y1)²), where (x1, y1) and (x2, y2) are the coordinates of the two points. Substituting the given values, the distance d can be calculated as follows:
√((-4 - 2)² + (8 - 5)²) = √((-6)² + (3)²) = √(36 + 9) = √(45) = 3√(5)
Therefore, the distance between the points (2, 5) and (-4, 8) is 3√(5) units.
A refrigerator is priced at $1,250. There are two options offered to reduce the price: either a 25% discount off the price or a rebate of $300. Which is the better choice, and what is the extra amount saved?
A.The 25% discount is better; it saves $12.50.
B.The rebate is better; it saves $12.50.
C.The 25% discount is better; it saves $75.
D.The rebate is better; it saves $75.
Answer:
A.The 25% discount is better; it saves $12.50.
Step-by-step explanation:
Here, the given marked price of the refrigerator = $ 1250,
In first option,
Discount percentage = 25 %,
Thus, total discount = 25 % of the marked price
= 0.25 × 1250
= 312.5
Thus, the selling price = 1250 - 312.5 = $ 937.5,
In second option,
Discount = $ 300,
Thus, the selling price = 1250 - 300 = $ 950,
Since, 937.5 < 950
Hence, First option is better than that of second.
Also, total saving = 950 - 937.5 = $ 12.5
⇒ The 25% discount is better; it saves $12.50

For any given rational function, differentiate between a function’s vertical and horizontal asymptotes. In two or more complete sentences, make a connection between the asymptotes and the function’s domain and range.
Consider the function
f(x) = [tex]\frac{x-3}{x-4}[/tex]
Domain of the function = All real numbers except , x≠4 .
[tex]y=\frac{x-3}{x-4} \\\\ xy - 4y = x-3 \\\\ x y -x= 4 y-3\\\\ x=\frac{4 y-3}{y-1}[/tex]
Range = All real numbers except , y≠1 .
Horizontal Asymptote= Since the degree of numerator and denominator of rational function is same , So Divide coefficient of x in numerator by divide coefficient of x in denominator.
So Horizontal Asymptote , is : y=1
To get vertical asymptote, put
Denominator =0
x-4=0
x=4 , is vertical asymptote.
Domain = All real numbers except vertical Asymptote
Range = All real numbers except Horizontal Asymptote
Final answer:
The vertical asymptotes of a rational function can be found by determining the roots of the polynomial in the denominator, while the horizontal asymptotes can be determined by analyzing the behavior of the function as x approaches infinity. The asymptotes are closely related to the function's domain and range.
Explanation:
Vertical asymptotes of a rational function can be determined by finding the roots of the polynomial in the denominator. Each root corresponds to a vertical asymptote. For example, if the polynomial has a factor of (x - 2), then there is a vertical asymptote at x = 2.
On the other hand, horizontal asymptotes of a rational function can be found by analyzing the behavior of the function as x approaches positive or negative infinity. If the leading terms of the numerator and denominator have the same degree, then the function will have a horizontal asymptote. For instance, if the leading terms are both x^2, then the horizontal asymptote will be y = 0.
The domain of the function is the set of all valid inputs, while the range is the set of possible outputs. The vertical asymptotes and the behavior of the function as x approaches infinity are closely related to the domain, while the horizontal asymptotes are related to the range.
