Given System of equation has multiple solution.

Simultaneous equations, a system of equations Two or more equations in algebra must be solved jointly (i.e., the solution must satisfy all the equations in the system). The number of equations must match the number of unknowns for a system to have a singular solution.

There are four methods for solving systems of equations: graphing, substitution, elimination, and matrices.

Given a system of equation:

-1 = 2x - y and  8x - 4y = -4​

From equation 1

-1 = 2x - y

y = 2x + 1

Substitute this value on equation 2

8x - 4y = -4​

8x - 4(2x + 1) = -4

-4 = -4

An equation can have infinitely many solutions when it should satisfy some conditions. The system of an equation has infinitely many solutions when the lines are coincident, and they have the same y-intercept. If the two lines have the same y-intercept and the slope, they are actually in the same exact line.

Thus, Given System of equation has multiple solution.

The meaning of (p⋅c)(2) for the horse-drawn carriage tour company is: A. the horse-drawn carriage tour company can expect to take in $5760 when the charge per customer is $60.

In this scenario, a function which represents the price charged per customer c(x) is given by this mathematical expression;

c(x) = 50 + 5x.

where:

x represents the number of $5 increases they charge over a rate of $50 per person.

When x = 2, the price charged per customer c(x) is given by;

c(2) = 50 + 5(2)

c(2) = $60.

Furthermore, a function which represents the number of customers expected for the day is given by:

p(x) = 100 - 2x

where:

x represents the number of $5 increases they charge over a rate of $50 per person.

When x = 2, the number of customers expected for the day is:

p(2) = 100 - 2(2)

p(2) = 96.

Now, (p⋅c) can be calculated as follows;

(p⋅c) = p(2) × c(2)

(p⋅c) = 96 × 60

(p⋅c) = $5760.

The values of the following are:

Sin A = 0.71

Cos A = 0.71

Sin B = 0.71

Cos B = 0.71

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

Right triangle ABC.

∠C = 90

The other two sides are a = 8 and b = 8

This means,

The angle opposite to the side a = 8 and b = 8 are equal.

Now,

∠A = ∠C

∠C + ∠A + ∠B = 180

90 + ∠A + ∠B = 180

2∠A = 180 - 90

∠A = 90/2

∠A = 45

∠B = 45

Now,

c² = a² + b²

c² = 64 + 64

c² = 128

c = √128

c = 11.31

Thus,

Sin A = a/c = 8/11.31 = 0.71

Cos A = b/c = 8/11.31 = 0.71

Sin B = b/c = 8/11.31 = 0.71

Cos B = a/c = 8/11.31 = 0.71

Answer: √6/8 x √6/18

Step-by-step explanation: The square root of A over B is the same as the squared of A, so it's important to know that before I start with this product. To go over the square.

I can do that if I combine the two square roots under the exact square root. This is only for multiplication.

I could take the square root of the term separately

Based on the graph of the general solution to the differential equation dy/dx = 2x + y, the option C: The slopes are all positive in Quadrant 1, is true.

What is a differential equation?

A differential equation is an equation that contains at least one derivative of an unknown function, either a normal differential equation or a partial differential equation.

The given the differential equation is dy/dx=2x+y.

The graph for the function is drawn.

dy/dx=2x+y

Now slope=2x+y

Along x-axis, y=0.

So, slope=2x≠0.

Since it depends upon x hence the slope along the y-axis are not horizontal.

Along y-axis, x=0.

So, slope=y≠0.

Since  it depends upon y the slope along the x-axis are also not horizontal.

In quadrant I -

x,y≥0

So, dy/dx≥0

Hence the slopes are all positive in quadrant I.

In quadrant IV -

Answer:

a) To determine the monthly mortgage payment, we first need to calculate the amount of the loan, which is equal to the purchase price of the house minus the down payment. In this case, the loan amount is 250,000 * 0.8 = 200,000. Next, we need to calculate the monthly interest rate, which is equal to the annual interest rate divided by 12. In this case, the monthly interest rate is 0.12/12 = 0.01. Using the formula for the monthly mortgage payment (P = L[i(1+i)^n]/[(1+i)^n-1]), where P is the monthly payment, L is the loan amount, i is the monthly interest rate, and n is the number of payments (in this case, 30 years * 12 = 360), we can calculate the monthly payment as:

P = 200,000[0.01(1+0.01)^360]/[(1+0.01)^360-1] = 1326.91

b) To calculate the total amount of interest Ato Liku will pay over the life of the mortgage, we can subtract the original loan amount from the total amount of payments made over the life of the mortgage. In this case, that would be 360 * 1326.91 - 200,000 = 480,596.

c) To determine the amount of the mortgage Ato Liku will have paid after 10 years, we can multiply the monthly mortgage payment by the number of payments made in 10 years (10 years * 12 = 120). In this case, that would be 120 * 1326.91 = 159,223.20.

Here x = 5, The two angles are ∠B = 41° and ∠C=  63°.

A pentagon is a 2D polygon with five sides and five angles.

Pentagon is formed from three triangles, so the sum of angles in a pentagon = 3 × 180° = 540°.

We are given in the figure , following information about a pentagon:

3 angles are 90 degrees, one angle is (6x+1) degrees, and the other angle is (8x-11) degrees.

To solve for x, we need to add all of the angles together.

The sum of the angles in any polygon is always equal to (n-2)*180, where n is the number of sides in the polygon.

In this case, n=5, so the sum of the angles is (5-2)*180 = 540 degrees.

We can now solve for x by substituting our known values into the equation.

540 = 90 + (6x + 1) + (8x - 11)

540 = 14x

x = 540/14

x = 5

Answer:

  5.1% increase

Step-by-step explanation:

You want the percentage change in price per load when the price of detergent went from $16.99 for 52 loads to $16.49 for 48 loads.

The percentage change is given by the formula ...

  ((new price)/(old price) -1) × 100%

The price per load is found by dividing the price of the bottle of detergent by the number of loads it will wash.

  old price per load = $16.99/52 ≈ $0.32673

  new price per load = $16.49/48 ≈ $0.34354

Then the percentage change is ...

  (0.34354/0.32673 -1) × 100% ≈ 0.05145 × 100% ≈ 5.1%

The price per load has increased by about 5.1%.

Step-by-step explanation:

b. There is 5% probability that a true null hypothesis will be rejected.

A p-value of 0.05 represents the probability of obtaining a test statistic as extreme or more extreme than the one observed under the assumption that the null hypothesis is true. In other words, it is the probability of observing the data or more extreme data assuming the null hypothesis is true. It is also the threshold level of significance beyond which the null hypothesis is rejected in favor of the alternative hypothesis. A p-value of 0.05 means that there is a 5% probability that the observed results occurred by chance under the null hypothesis and that there is a 95% probability that the observed results occurred due to a real effect.

The purple line would be plotted at the level of output $60 billion, and the orange line segments would be plotted at 90, 95, 100, 105, and 110 respectively.

1. Plot the purple line at the level of output $60 billion.

2. Plot the orange line segments at 90, 95, 100, 105, and 110 respectively.

The long-run aggregate supply (RAS) curve is used to represent the natural level of output for an economy. In this case, the natural level of output is $60 billion of real GDP with a price level of 100. Therefore, the purple line should be plotted at the level of output $60 billion on the graph. The short-run aggregate supply (AS) curve is used to show how the level of output reacts to the price level. Therefore, the orange line segments should be plotted at 90, 95, 100, 105, and 110 respectively. This will show how the level of output changes when the price level is different from the natural level. This will help to illustrate how the economy may react when the price level is different than expected.
