Answer:

A. (2, 18, -19)

Step-by-step explanation:

To solve:

Z is the most suitable variable to remove first

Add the first equation to the second equation: (this conveniently removes both y and z)

(x+y-z) + (4x-y+z) = 1+9

Simplify

5x = 10

Solve

x = 2

Multiply the second equation by 2 and minus it to the third equation: (Solve for y)

2(4x-y+z) - (x-3y+2z) = 2(9) - (-14)

Simplify

8x-2y+2z-x+3y-2z=18+14

7x+y=32

Substitute using x=2

7(2) + y = 32

y = 32 - 14

y = 18

Now substitute x and y for their respective values into Equation 1

2 + (-18) - z = 1

Simplify

-z = 19

z = -19

So :

x = 2, y = 18 , z = -19

angle 2 is equal to angle 3( alternate angles)

Angles in parallel lines are angles that are created when two parallel lines are intersected by another line called a transversal. We can use the information given in the diagram to find any angle around the intersecting transversal.

If angle 1 = angle 4

to prove: angle 2 = angle 3

angle 1 = angle 2 ( opposite angles )

angle 3 = angle 4 ( opposite angles)

(Just because I'm a high schooler doesn't mean that I don't know this I take AP and IB classes)

Fractions are numbers that have a numerator and a denominator. The numerator is the number at the top and the denominator is the number below.

They are represented as:

\(\frac{x}{y}\) , where x = numerator, y = denominator.

\(\frac{3}{4}\) to the power of 4 is \(\frac{81}{256}\)

3/4 to the power of 4 as a fraction is written as :

\((\frac{3}{4} )^{4}\)

= \(\frac{3^{4} }{4^{4} }\)

= \(\frac{3*3*3*3}{4*4*4*4}\)

= \(\frac{81}{256}\)

Therefore, \(\frac{3}{4}\) to the power of 4 is \(\frac{81}{256}\)

The expected total dollar net operating Income for next year = $70,000

1) The contribution format income statement for the game last year, and the degree of operating leverage is computed below:

Contribution format income statement for the game last year Sales (15,000 × $20) = $300,000

Variable expenses (15,000 × $6) = $90,000

Contribution margin = $210,000

Fixed expenses = $182,000Net operating income = $28,000

Degree of operating leverage = Contribution margin / Net operating income= $210,000 / $28,000= 7.5 2)

The expected percentage increase in net operating income for next year:

The expected sales in next year = 18,000

games selling price per game = $20

Therefore, Total sales revenue = 18,000 × $20 = $360,000

Variable expenses = 18,000 × $6 = $108,000

Fixed expenses = $182,000

Expected net operating income = Total sales revenue – Variable expenses – Fixed expenses

= $360,000 – $108,000 – $182,000= $70,000

The expected percentage increase in net operating income = (Expected net operating income - Last year's net operating income) / Last year's net operating income*100= ($70,000 - $28,000) / $28,000*100= 150%

Answer:9 5/24

Step-by-step explanation:

The factorization of\(8(p-q)^3-(p+q)^3 is 8(p-q)^3 - (p+q)^3 is [p - 3q][7p^2 - 8pq + 3q^2].\)

The given expression is\(8(p-q)^{3}-(p-q)^{3}\)

To factorize this expression, we can use the identity for the difference of cubes, which states that \(a^3 - b^3 = (a - b)(a^2 + ab + b^2).\)

Let's apply this identity to the given expression:

\(8(p-q)^3 - (p+q)^3 = [2(p-q)]^3 - (p+q)^3.\)

Now we can see that we have a difference of cubes:\((2(p-q))^3 - (p+q)^3.\)

Using the identity, we can factorize this expression as follows:

\([(2(p-q)) - (p+q)][(2(p-q))^2 + (2(p-q))(p+q) + (p+q)^2].\)

Simplifying further:

\([2p - 2q - p - q][(2(p-q))^2 + (2(p-q))(p+q) + (p+q)^2].\)

Combining like terms:

\([p - 3q][(2(p-q))^2 + 2(p-q)(p+q) + (p+q)^2].\)

Expanding the squared term:

\([p - 3q][4(p^2 - 2pq + q^2) + 2(p^2 - q^2) + (p^2 + 2pq + q^2)].\)

Simplifying:

\([p - 3q][4p^2 - 8pq + 4q^2 + 2p^2 - 2q^2 + p^2 + 2pq + q^2].\)

Combining like terms again:

\([p - 3q][7p^2 - 8pq + 3q^2].\)

Therefore, the factorization of \(8(p-q)^3 - (p+q)^3 is [p - 3q][7p^2 - 8pq + 3q^2].\)

Answer:

no solutions

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

equation of blue line is y = x + 2 , in slope- intercept form

with slope m = 1

equation of red line is y = x - 3 , in slope- intercept form

with slope m = 1

• Parallel lines have equal slopes

then the blue and red lines are parallel.

the solution to the system is at the point of intersection of the 2 lines

since the lines are parallel then they do not intersect each other.

thus the system shown has no solution.

The monthly PMI Payment for Christina's loan is $37.50.The correct answer is option B.

To determine Christina's monthly PMI (Private Mortgage Insurance) payment, we need to find the corresponding interest rate for her loan-to-value (LTV) ratio. The LTV ratio is calculated by dividing the loan amount by the property value.

The loan amount can be calculated by subtracting the down payment from the property value:

Loan amount = Property value - Down payment

           = $170,000 - $20,000

           = $150,000

Now we can calculate the LTV ratio:

LTV ratio = Loan amount / Property value * 100

         = $150,000 / $170,000 * 100

         = 88.24%

Since Christina is obtaining a 30-year mortgage, we need to look at the interest rates for LTV ratios between 85.01% and 90%. According to the table, the interest rate for this range is 0.30%.

To calculate the PMI payment, we multiply the loan amount by the PMI rate and divide it by 12 months:

PMI payment = (Loan amount * PMI rate) / 12

           = ($150,000 * 0.30%) / 12

           = $450 / 12

           = $37.50
