Answer:

  b.  $154,810

Step-by-step explanation:

You want to know the price of a home that can be purchased for a monthly payment of $879.32 on a 30-year loan at 5.5%.

The given table tells you the multiplier m used to find the monthly payment p from the loan amount P for different time periods and interest rates.

  p = (P/1000)×m

The table value for a 30-year loan at 5.5% is m = 5.68. Solving the equation for P, we have ...

  1000p/m = P

  1000(879.32/5.68) = P ≈ 154,809.86 ≈ 154810

You qualify for a loan of $154,810.

__

Additional comment

The multiplier 5.68 is found on row 2 (5.5%) of column 4 (30 years).

By answering the presented question, we may conclude that As a result, equation the answer is (b) $154,810.

A mathematical equation is a formula that connects two statements and denotes equivalence with the equals symbol (=). An equation is a mathematical statement that shows the equality of two mathematical expressions in algebra. In the equation 3x + 5 = 14, for example, the equal sign separates the variables 3x + 5 and 14. A mathematical formula describes the connection between the two sentences that occur on opposite sides of a letter. The symbol and the single variable are frequently the same. As in 2x - 4 Equals 2, for instance.

To establish the purchase price of a property, we must use the monthly payment and the table supplied to determine the mortgage amount that corresponds to the monthly payment.

According to the data, the monthly payment per $1000 of mortgage for a 30-year fixed mortgage at a 5.5% interest rate is $5.68.

Hence, to calculate the mortgage amount for a $879.32 monthly payment, we may apply the following formula:

Mortgage amount = monthly payment / mortgage payment per $1000

$879.32 mortgage amount / $5.68 per $1000

Loan amount = $154,810

As a result, the purchasing price of a house is $154,810.

As a result, the answer is (b) $154,810.

An inequality for the number of tickets the theater club needs to sell is 10x+8y ≤ 800 and need to sell at the door to reach its goal is 48.

Given,

In the question:

Tickets to a play cost $10 at the door and $8 in advance. The theater club wants to raise at least $800 from the sale of the tickets from the play.

If the club sells 40 tickets in advance.

To Write and graph an inequality for the number of tickets the theater club needs to sell. Use x to represent the number of tickets sold at the door and y to represent the number of tickets sold in advance.

Now, According to the question;

Standard form of the inequality is:

10x + 8y ≤ 800

Slope intercept form:

y < (-5/4)x + 100

Slope: -5/4

y-intercept: 100

Tickets sell at the door to reach its goal is:

10x + 8*40 = 800

10x + 320 = 800

10x = 800 - 320

10x = 480

divide by 10 on both sides

x = 480/10

x = 48

Hence, An inequality for the number of tickets the theater club needs to sell is 10x+8y ≤ 800 and need to sell at the door to reach its goal is 48.

Answer: C

Step-by-step explanation:

Point D is at -14 on the number line.

In Mathematics, the midpoint of a line segment with two end points can be calculated by adding each end point on a line segment together and then divide by two (2).

Since E is the midpoint of line segment CD, we can logically deduce the following relationship:

Line segment CD = Line segment C + Line segment D

Midpoint E = (point C + point D)/2

By substituting the given points into the equation above, we have the following:

-3 = (8 + D)/2

-6 = 8 + D

D = -6 - 8

D = -14

Answer:

\(z = 3 + i\) is complex as \(a,b\in \mathbb{R}\), \(b \neq 0\).

Step-by-step explanation:

A complex number comprehends all numbers of the form:

\(z = a+i\cdot b\), \(\forall \,a,b\in \mathbb{R}\)

Where \(i = \sqrt{-1}\).

In other words, complex numbers are an extension of real numbers.

There is the following classification depending on what values of \(a\) and \(b\) exist:

Real - \(a \in \mathbb{R}\), \(b = 0\)

Complex - \(a,b\in \mathbb{R}\), \(b \neq 0\)  

Pure imaginary - \(a = 0\), \(b \neq 0\) (The term "nonreal complex" is a synonym for pure imaginary complex)

Let be \(z = 3 + i\), which is complex as \(a,b\in \mathbb{R}\), \(b \neq 0\).

The number contains both real and imaginary parts, hence it is classified as a complex number.

Complex numbers are square roots of negative numbers. They are represented using the letter "i".

Complex number is expressed as z = x + iy where:

Given the value 3+i, since the number contains both real and imaginary parts, hence it is classified as a complex number.

The dairy farmer should use 400 pounds of the 75% protein supplement and 800 pounds of the 30% protein ration to make 1200 pounds of a high-grade 45% protein ration.

To determine how many pounds of each protein supplement the dairy farmer should use, we can set up a system of equations based on the given information.

Let's denote the following:

x = pounds of the 75% protein supplement

y = pounds of the 30% protein ration

The total weight of the mixture is 1200 pounds, so we have the equation:

x + y = 1200

The protein content in the mixture should be 45% of the total weight, so we have the equation:

0.75x + 0.30y = 0.45 * 1200

Now we can solve this system of equations.

First, let's rewrite the second equation in decimal form:

0.75x + 0.30y = 540

To make it easier to work with, we can eliminate the decimals by multiplying both sides of the equation by 100:

75x + 30y = 54000

Now we have a system of equations:

x + y = 1200

75x + 30y = 54000

We can solve this system using any appropriate method, such as substitution or elimination. In this case, let's use the substitution method:

Solve the first equation for x:

x = 1200 - y

Substitute the value of x into the second equation:

75(1200 - y) + 30y = 54000

Simplify and solve for y:

90000 - 75y + 30y = 54000

-45y = -36000

y = 800

Now we can substitute the value of y back into the first equation to find x:

x + 800 = 1200

x = 1200 - 800

x = 400

The cups of giardia-laced lemonade that Wiyot will have sold by the time his parents get a call from county health officials on day 8 is 75 cups.

From the information, Wiyot sells 33 lemonades on the first day, and 6 additional lemonades each day as the summer heats up.

This is an arithmetic sequence and will be expressed as:

= a + (n - 1)d

a = first term = 33

d = common difference = 6

n = 8

A function is an equation that has only one answer for y for every x. A function assigns exactly one output to each input of a specified type. It is common to name a function either f(x) or g(x) instead of y. f(2) means that we should find the value of our function when x equals 2. Example.

Step-by-step explanation:

The domain and range of the given function plotted on the graph is -

Domain : x ≥ -5

Range : y ≥ -2

Range of the function is the set of {y} - values that exist for a given value of {x} or for the existing domain of the function. As it can be seen from the graph that the {y} values range from -2 {included} to ∞ {excluded}. So, the range of the given function is [-2, 2).

Domain is the set of {x} values for which the function exist. We can see that the function values are in range [-5, ∞).
