The solution of the given equation -4(n+5)=-32 is n=3.
What is equations ?
An equation is a mathematical statement that shows that two expressions are equal. It contains an equals sign (=) between two expressions. The expressions on both sides of the equals sign have the same value. Equations are used to solve problems in mathematics and science.
To solve the equation, we need to isolate the variable n.
-4(n+5) = -32
Distribute -4 on the left side of the equation:
-4n - 20 = -32
Add 20 to both sides of the equation:
-4n = -12
Divide both sides by -4:
n = 3
Therefore, the solution of the given equation -4(n+5)=-32 is n=3.

The principal P is borrowed at a simple interest rate r for a period of time t. Find the loan's future value A, or the total amount due at time t.
P=$1000, r=5.0%, t=6 months
Step-by-step explanation:
To calculate the future value of a loan with simple interest, we can use the formula:
A = P(1 + rt)
where A is the future value or total amount due, P is the principal, r is the interest rate, and t is the time period in years.
In this case, we have:
P = $1000
r = 5.0% = 0.05 (expressed as a decimal)
t = 6 months = 0.5 years (since there are 12 months in a year)
Plugging these values into the formula, we get:
A = $1000(1 + 0.05 x 0.5)
A = $1000(1.025)
A = $1025
Therefore, the future value or total amount due on the loan after 6 months is $1025.

(4a^-2)^-1/2 simplify
Answer: To simplify the expression, we can apply the exponent rule for powers of powers which states that to raise a power to another power, we multiply the exponents.
So,
(4a^(-2))^(-1/2) = 4a^(-2 * (-1/2)) = 4a^(1) = 4a
Therefore, (4a^-2)^-1/2 simplifies to 4a.

Which equations represent circles that have a diameter of 12 units and a center that lies on the y-axis? Select two options.
x2 + (y – 3)2 = 36
x2 + (y – 5)2 = 6
(x – 4)² + y² = 36
(x + 6)² + y² = 144
x2 + (y + 8)2 = 36
Since the center of the circle lies on the y-axis, the x-coordinate of the center must be 0.
Also, since the diameter of the circle is 12 units, the radius is half of that, or 6 units.
Using the standard form of the equation of a circle, which is (x - h)^2 + (y - k)^2 = r^2, where (h, k) is the center of the circle and r is the radius, we can substitute the values we know and simplify the equations to see which ones match.
The equations that represent circles with a diameter of 12 units and a center that lies on the y-axis are:
x^2 + (y - 6)^2 = 36 (center is at (0, 6))
x^2 + (y + 6)^2 = 36 (center is at (0, -6))
Therefore, the two options that represent the circles with the given properties are:
x^2 + (y - 6)^2 = 36 and x^2 + (y + 6)^2 = 36.

What are the purchase terms?Conditions of sale are the rules that govern a business transaction, including the cost, the method of payment, the delivery, and any other pertinent information. Normally, they are specified in a sales contract or invoice and acknowledged in advance of the transaction. The conditions of sale might alter based on the type of products or services being exchanged, the volume and complexity of the deal, and other elements.
We know that,
Cash discount = amount x discount rate
Net amount due = amount - cash discount

What is Function?
Function is the relationship between inputs where each input is related to exactly one output. It is a special relationship among the inputs (i.e. the domain) and their outputs (known as the codomain) where each input has exactly one output, and the output can be traced back to its input.
"y is a function of x" (denoted y = f(x)) means that y varies according to whatever value x takes on.
How to determine
Where F(x) = 2x^4 + x^2 - 10x + 1
So, to calculate f(-10)
f(x) = y
Where x = -10
f(-10) = 2(-10)^4 + (-10)^2 -10(-10) + 1
f(-10) = 2(10000) + 100 + 100 + 1
f(-10) = 20000 + 100 + 100 + 1
f(-10) = 20201
For f(2),
f(x) = y
Where x = 2
f(2) = 2(2)^4 +2^2 -10(2) + 1
f(2) = 2(16) + 4 -20 + 1
f(2) = 32 + 4 -20 + 1
f(2) = 17
For f(3)
f(x) = y
Where x = 3
f(3) = 2(3)^4 + 3^2 -10(3) + 1
f(3) = 2(81) + 9 -30 + 1

The mean of the following data values is 36.
19, 23, 35, 41, 42
Answer:
To find the mean of a set of data, we need to sum up all the values in the set and divide by the number of values.
Sum of the data values = 19 + 23 + 35 + 41 + 42 = 160
Number of data values = 5
Mean = Sum of data values / Number of data values = 160 / 5 = 32
However, we are given that the mean is 36. Since the calculated mean is lower than the given mean, it means that we are missing a value that is higher than the other values in the set.
Let's call this missing value x. Then, we have:
(19 + 23 + 35 + 41 + 42 + x) / 6 = 36
Multiplying both sides by 6, we get:
19 + 23 + 35 + 41 + 42 + x = 216
Simplifying the left-hand side, we get:
160 + x = 216
Subtracting 160 from both sides, we get:
x = 56
Therefore, the missing value is 56, and the complete data set is:
19, 23, 35, 41, 42, 56
Now, we can calculate the mean as:
Mean = (19 + 23 + 35 + 41 + 42 + 56) / 6 = 216 / 6 = 36
So, the mean of the data values is indeed 36.
Answer:
32
Step-by-step explanation:
To find the mean of a set of numbers, we add up all the numbers and then divide by the total number of values.
Adding up the values:
19 + 23 + 35 + 41 + 42 = 160
We have a total of 5 values, so we divide the sum by 5:
160 / 5 = 32
Therefore, the mean of the given data values is 32, not 36.

1. Hiro has 18 highlighters, which is 4 fewer than Martin has. How many markers
does Martin have?
what are the steps???
Answer:
Let's use algebra to solve this problem:
Let's use the variable "m" to represent the number of markers that Martin has.
We know that Hiro has 4 fewer highlighters than Martin, so we can set up an equation:
18 = m - 4
This equation says that the number of markers Martin has (m) minus 4 is equal to the number of highlighters that Hiro has (18).
To solve for "m", we can add 4 to both sides of the equation:
18 + 4 = m
Simplifying this gives us:
22 = m
So Martin has 22 markers.

The function g(x) = 3/(x-2) + 5 is a transformation of the parent function f(x) = 1/x with a horizontal shift of 2 units to the right, a vertical stretch by a factor of 3, and a vertical shift of 5 units up.
What is the transformation of the functionThe function g(x) = 3/(x-2) + 5 is a transformation of the parent function f(x) = 1/x.
Here are the transformations that were applied to f(x) to obtain g(x):
1. Horizontal shift: The denominator of f(x) is x, which means that the vertical asymptote is at x = 0. By subtracting 2 from x in the denominator of g(x), we are shifting the vertical asymptote to x = 2. This is a horizontal shift of 2 units to the right.
2. Vertical stretch: The coefficient 3 in front of the fraction means that the function is stretched vertically by a factor of 3 compared to f(x). This means that the distance between the horizontal asymptotes (which are at y = 0 for f(x) and y = 5 for g(x)) is three times larger for g(x) than for f(x).
3. Vertical shift: The constant 5 added to the fraction means that the entire function is shifted vertically by 5 units compared to f(x). This means that the horizontal asymptote of g(x) is at y = 5 instead of y = 0.

Accordingly,
62 + 69 + 4x + 5 = 180
Combine like terms.
136 + 4x = 180
