The variable 'c' in the given expression has No Solution.

Given, that

2/3c - 1 = 1 + 2/3c

Now, as we have same coefficient of the variable c i.e. 2/3

So, On subtracting 2/3c from both the sides, we get

2/3c - 2/3c - 1 = 1 +2/3c - 2/3c

-1 ≠ 1

Hence, we got no solutions that can satisfy the given expression.

So, the variable 'c' in the given expression has No Solution.

Answer:

The lines through the given points are parallel

Step-by-step explanation:

The given lines can be evaluated as follows

The first step is to calculate the slope [tex]m_{1}[/tex] of the first line using the slope formula as follows

[tex]m_{1}=\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

Take two coordinates on the first line

[tex](10,5)~\text{and}~(-8,9)[/tex]

Substitute [tex]9[/tex] for [tex]y_{2}[/tex], [tex]-8[/tex] for [tex]x_{2}[/tex] , [tex]5[/tex] for [tex]y_{1}[/tex] , [tex]10[/tex] for [tex]x_{1}[/tex]  in the slope formula

[tex]m_{1}=\frac{9-5}{-8-10}[/tex]

Simplify the numerator and the denominator at the right side of the equation

[tex]m_{1}=\frac{4}{-18}[/tex]

Simplify the fraction at the right side of the equation

[tex]m_{1}=-\frac{2}{9}[/tex]

The slope of the first line is [tex]-\frac{2}{9}[/tex]

Take two coordinates on the second line

[tex](2,-4)~\text{and}~(11,-6)[/tex]

Substitute [tex]-6[/tex] for [tex]y_{2}[/tex], [tex]11[/tex] for [tex]x_{2}[/tex] , [tex]-4[/tex] for [tex]y_{1}[/tex] , [tex]2[/tex] for [tex]x_{1}[/tex]  in the slope formula

[tex]m_{2}=\frac{-6-(-4)}{11-2}[/tex]

Take out the brackets in the numerator at the right side of the equation

[tex]m_{2}=\frac{-6+4}{11-2}[/tex]

Simplify the numerator and the denominator at the right side of the equation

[tex]m_{2}=\frac{-2}{9}[/tex]

The slope of the second line is [tex]-\frac{2}{9}[/tex]

Since the slope of both lines are equal, then the lines through the given points are parallel

Hence the lines through the given points are parallel

The factoring of the polynomial f(x) = x^4 + 3x³ - 2x² + 48x - 288 is given as follows:

f(x) = (x - 4i)(x + 4i)(x + 6)(x - 3).

The polynomial is factored by it's linear factors, given as follows:

f(x) = (x - x')(x - x'')(x - x''')(x - x'''').

In which x', x'', x''' and x'''' are the roots of the polynomial f(x).

In this problem, we have that -4i is a root, hence, by the Conjugate Roots Theorem, 4i is also a root and hence:

f(x) = (x - 4i)(x + 4i)(x - x''')(x - x'''').

f(x) = (x² + 16)(x - x''')(x - x'''').

As a fourth order polynomial can be the product of two second order polynomials, hence:

x^4 + 3x³ - 2x² + 48x - 288 = (x² + 16)(ax² + bx + c)

x^4 + 3x³ - 2x² + 48x - 288 = ax^4 + bx³ + (c + 16)x² + 16bx + 16c.

Hence the coefficients are given as follows:

Then the equation for the final two factors is:

x² + 3x - 18 = 0.

Which is simplified as follows:

x² + 3x - 18 = (x + 6)(x - 3).

Hence the simplified polynomial is:

f(x) = (x - 4i)(x + 4i)(x + 6)(x - 3).

The probability that the random variable has a value greater than 7 is undetermined.

The formula to calculate the probability of occurrence of an event 'A' can be written as -  

P(A) = n(A)/n(S)

where -

n(A) = Number of outcomes favorable to event A.

n(S) = Total number of outcomes

We have a random variable having a value greater than 7

Now -

Number of outcomes favorable to event A = (-∞, + ∞) - (- ∞, 7)

Total number of outcomes for event A = (-∞, + ∞)

P(A) = (-∞, + ∞) - (- ∞, 7) /  (-∞, + ∞)

P(A) = ∞/∞

P(A) = undetermined

Therefore, the probability that the random variable has a value greater than 7 is undetermined.

By changing both equations to slope-intercept, it is easier to determine whether two lines are perpendicular.

Since [tex]y = \frac{5}{2} x+ 5[/tex] is already in slope-intercept form, we just need to change the first given equation.

2x + 5y + 3 = 0

2x + 5y = -3

5y = -2x -3

[tex]y=\frac{-2}{5}x-\frac{3}{5}[/tex]

Two lines are perpendicular when the slope of the lines (coefficient of x) are negative reciprocals (opposite sign of the inverse of a number).

Comparing the two slopes [tex]\frac{5}{2}[/tex]  and [tex]\frac{-2}{5}[/tex], we can see they they both fit the criteria of being opposite signs and inverses of each other.

So  2x + 5y + 3 = 0 is perpendicular to y = (5/2)x+ 5.

Bank A grants a shorter payment period and is the least costly, so the Ruffins should take the loan from Bank A.

In finance literature and practice, the loan interest (cost) increases with a more extended payment period.

In other words, a shorter payment period reduces the interest cost of a loan.  The loan cost is also influenced by the amount of the principal and the interest rate.

Down payment = 25%

Interest rate = 11%

Mortgage period = 25 years

2 points at closing

N (# of periods) = 300 months (25 years x 12)

I/Y (Interest per year) = 11%

PV (Present Value) = $142,500 ($190,000 - $47,500)

FV (Future Value) = $0

Results:

Period Payments (PMT) = $1,396.66

Sum of all periodic payments = $418,998

Total Interest = $276,498

Down payment = $47,500 ($190,000 x 25%)

2 points = $2,850 ($142,500 x 2%)

Sum of periodic payments = $418,998

Total costs = $469,348 ($47,500 + $2,850 + $418,998)

Down payment = 15%

Interest rate = 10%

Mortgage period = 30 years

N (# of periods) = 360 months (30 years x 12)

I/Y (Interest per year) = 10%

PV (Present Value) = $161,500

FV (Future Value) = $0

Results:

Period Payments (PMT) = $1,417.28

Sum of all periodic payments = $510,220.08

Total Interest = $348,720.08

Down payment = $28,500 ($190,000 x 15%)

Sum of periodic payments = $510,220.80

Herein we find a function whose first derivative has to be found. This can be done by using the following derivative rules:

Derivative of a power

f(x) = c · xⁿ → f'(x) = n · c · xⁿ ⁻ ¹

Chain rule

f[g(x)] = (df / dg) · (dg / dx)

Derivative of a sum of functions

(c) z = x + y

(d) There is one solution. The man invested $90,000 at 6.5%, $140,000 at 7% and $230,000 at 9%

A system of equations are two or more equations that have variables that are common to the equations in the system.

The questions in the parts (a) to (d) obtained from a similar question are;

(a) An equation stating the sum of the three investments

(b) The equation that states that of the sum of the return is 36,350

(c) The equation that states that the amount invested at 9% equals the sum of the other two investments

(d) Solve the derived system of equations

(a) The amount the man invests in the three rental properties = $460,000

Amount invested in the property that earns 6.5% = x

Amount invested in the property that earns 7% = y

The amount invested in the property that earns 9% = z

The equation that represents the sum of the three investments is therefore;

x + y + z = 460,000...(1)

(b) The equation that represents the sum of the returns from the three investment is found as follows;

6.5% = 0.065, 7% = 0.07, 9% = 0.09

(c) The equation stating the amount invested at 9% equals the sum of the other two investment is; z = x + y...(3)

(d) The system of equations is solved as follows;

From equation (1) and (2), we get;

x + y + z = 460,000

z + z = 460,000

2·z = 460000

· = 460,000 ÷ 2 = 230,000

The amount invested in the property that earns 9% per year is $230,000

Equation (3) indicates;

0.65·x + 0.07·y + 0.09 × 230,000 = 36,350

0.65·x + 0.07·y = 36,350 - 0.09 × 230,000 = 15650

The interest earned in the properties that earn 6.5% and 7% = $15650

0.65·x + 0.07·y = 15650...(4)

x + y = 230000...(5)

Equation (4) and (5) indicates;

y = 230,000 - x

0.065·x + 0.07×(230,000 - x) = 15650

16100 - 0.005·x = 15650

0.005·x = 16,100 - 15,650 = 450

x = 450 ÷ 0.005 = 90,000

The amount invested in the property that yields 6.5% per year = $90,000

Therefore;

The amount invested in the property that earns 7% per year = $230,000 - $90,000 = $140,000

There is one solution, the man invested $90,000 at 6.5%, $230,000 at 7%, and $230,000 at 9%

The equation of the parabola from the vertex is f(x) = -3(x - 5)² + 9

The equation of the function is given as

f(x) = 3x²

Also, we have

Vertex = (5, 9)

The form of the equation is given as

f(x) = a(x - h)² + k

Where

Vertex = (h, k)

This means that

Vertex = (h, k) = (5, 9)

Substitute (h, k) = (5, 9) in the equation f(x) = a(x - h)² + k

So, we have

f(x) = a(x - 5)² + 9

This also means that

f(x) = -3(x - 5)² + 9
