The ordered pairs are (1,0), (2,6/5),(3,12/5)

The solution of a linear equation is defined as the points, in which the lines represent the intersection of two linear equations. In other words, the solution set of the system of linear equations is the set of all possible values to the variables that satisfies the given linear equation.

Given here: The equation as y = 6x/5 - 6/5

putting (1,0) in the equation we get 6×1/5-6/5=0

Similarly we can find the ordered pair as y = 6/5x - 6/5

Hence, The ordered pairs are (1,0), (2,6/5),(3,12/5)

Answer:

Infinitely many solutions

Step-by-step explanation:

The inequality that is represented on the given graph is;

y ≥ -2x + c

The general formula for equation of a line in slope intercept form is;

y = mx + c

where;

m is slope

c is y-intercept

Now, in this question, the coordinate of the y-intercept is (c, 0) and as such, the y-intercept is c.

Ths slope is gotten from two coordinates (2, -3) and (4, -7)

Slope = (-7 - (-3))/(4 - 2)

Slope = -4/2

Slope = -2

Now, the Inequalities that use < or > symbols are plotted with a dashed line to indicate that the line is not included in the region. Inequalities that use ≤ or ≥ symbols are plotted with a solid line to indicate that the line is included in the region.

Also, when we shade above the line, it is greater than and in this case it will be greater than or equal to since the line is a solid line to give the equation; y ≥ -2x + c

The measures of x and y in the congruent polygons are:

x = 7

y = 8

Congruent polygons are two or more polygons with the same number of sides and the same length for each side. In other words, they are polygons that have the same shape and size.

Two polygons are congruent if and only if it is possible to superimpose one polygon over the other by using a combination of translation, rotation and reflection. Congruent polygons have the same area and perimeter.

Therefore:

m<E = m<A

Substitute the values:

4y - 4 = 28

4y = 28 + 4

4y = 32

4y/4 = 32/4

y = 8

m<F = m<B

Substitute:

10x + 65 = 135

10x = 135 - 65

10x = 70

10x/10 = 70/10

x = 7

The derivative of the expression, x²yz³ + (x²yz³)³ with respect to z = (xy²z)² is:

d/dz (x²yz³ + (x²yz³)³) = d/dz (x²yz³) + d/dz ((x²yz³)³)

= 3x²y²z³ + 2x³yz⁴ + 3 * (x²yz³)² * (3x²y²z³ + 2x³yz⁴)

The derivative of the first term, x²yz³, with respect to z = (xy²z)² can be found using the chain rule:

d/dz (x²yz³) = d/dy (x²yz³) * dy/dz + d/dx (x²yz³) * dx/dz

= 3x²yz² * yz + 2x¹yz³ * xy²z

= 3x²y²z³ + 2x³yz⁴

The derivative of the second term, (x²yz³)³, with respect to z = (xy²z)² can be found using the chain rule and the power rule:

d/dz ((x²yz³)³) = d/dy (x²yz³)³ * dy/dz + d/dx (x²yz³)³ * dx/dz

= 3 * (x²yz³)² * (3x²yz² * yz + 2x¹yz³ * xy²z)

Pythagorean theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides.

We have,

Two right triangles.

Applying the Pythagorean theorem in the bigger triangle.

We get,

25² = 7² + Length²

25² = 49 + Length²

Length² = 625 - 49

Length² = 576

Length = √576

Length = 24

Now,

Applying the Pythagorean theorem in the smaller triangle.

We get,

x² = 4² + 24²

x² = 16 + 576

x² = 592

x² = 16 x 37

x = √(16 x 37)

x = √(4² x 37)

x = 4√37

Thus,

The value of x is 4√37.

Answer:  Ryan should sell his CDs for $13 to maximize his revenue.

Step-by-step explanation:

To find the price at which Ryan should sell his CDs to maximize his revenue, we need to use the information provided about the relationship between price and sales, and the formula for revenue (price x quantity sold).

Step 1: Identify the relationship between price and sales. We know that a $1 increase in the price of a CD leads to a drop of 5 CDs per week in sales.

Step 2: Create an equation that relates price, quantity sold, and revenue. Let P be the price of a CD, Q be the quantity sold, and R be the revenue. Then, we have R = P x Q

Step 3: Create a table that shows the relationship between price, quantity sold, and revenue.

Price Quantity Sold         Revenue

10       80                            800

11       75                              825

12      70                                     840

13     65                                        845

14     60                                         840

15     55                                        825

16     50                                   800

17     45                                  785

18     40                                720

19     35                                      665

20     30                                              600

Step 4: Identify the price that maximizes revenue. From the table we can see that the revenue is maximum at $13 which is 845 and this is the price at which Ryan should sell his CDs to maximize his revenue.

Therefore, Ryan should sell his CDs for $13 to maximize his revenue.

The distance between the centres of the two villages on the map is 16cm. The solution is obtained using the concept of unit conversion.

The same attribute is expressed using a unit conversion, but in a different unit of measurement. For instance, time can be expressed in minutes rather than hours, and distance can be expressed in kilometres, feet, or any other measurement unit instead of miles. Measurements are frequently offered in one set of units, like feet, but are required in another set, like chains.

Now, we are given the scale of a map as 1 : 50000 and that two villages are 8km apart on the map.

The scale of a map is given as 1 : 50000.

=> 1  cm on map  = 50,000 cm  on actual

We know that 1 km = 1,00,000cm

So,

=> 8km  = 8,00,000 cm

So, The distance on the map is

800000 / 50000

= 80/5

= 16 cm

Hence, the actual distance between them is 16cm.

The speed of the boat in still water is 12mikes per hour and the speed of the current is 6milesper hour

Speed is defined as, the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude.

speed = distance /time

speed with downstream = 90/5 = 18miles per hour

speed against down stream = 90/15 = 6 miles per hour

represent the speed of the boat in still water by x and the speed of the downstream by y

therefore x+y = 18 equation 1

x-y = 6 equation 2

subtract equation 2 from 1

2y = 12

y = 12/2 = 6miles/hour

substitute 6 for x in equation 1

x + 6 = 18

x = 18-6 = 12 miles/hour

therefore the speed of the boat with in still water is 12miles per hour and the speed of the current is 6 miles per hour

Answer:

(-7,3)

Step-by-step explanation:

The angle complementary to an acute angle A is always acute and smaller than 90 degrees, while the angle supplementary to angle A is always larger than 90 degrees, they cannot be equal since they are adding up to 90 degrees and 180 degrees respectively.

A complementary angle is a pair of angles that add up to 90 degrees. Two angles are said to be complementary if the sum of their measures is 90 degrees. The two angles are called complementary angles because they "complete" a right angle.

An angle is considered acute if it measures less than 90 degrees. A complementary angle is an angle that, when added to another angle, will sum up to 90 degrees. So, if angle A is acute, then its complement angle will also be acute.

On the other hand, an angle supplementary to angle A is an angle that, when added to angle A, will sum up to 180 degrees.

So, an angle complementary to an acute angle A is always acute and smaller than 90 degrees, while an angle supplementary to angle A will always be larger than 90 degrees. They can't be equal since they are adding up to 90 degrees and 180 degrees respectively.

For example, if angle A measures 60 degrees, its complementary angle will measure 30 degrees (90 - 60 = 30) and its supplementary angle will measure 120 degrees (180 - 60 = 120).

Answer:

[tex]x\ge -7[/tex]

Step-by-step explanation:

The square root function has a domain consisting of numbers greater than or equal to zero. This excludes negative numbers since the square root of a number, when multiplied by the same square root of a number results in the original number: [tex]y=\sqrt{x}\implies y*y=x[/tex]. If we wanted the square root of a negative number, we would need a number which multiplies by it self to get a negative number, but as you may recall, if we square a real number, we always get a positive. So negative numbers are not included in the domain (although there are imaginary solutions)

So we just need the inside of the square root to be greater than or equal to zero. Thus we can derive: [tex]x+7\ge 0[/tex] and then just subtract 7 from both sides to simplify: [tex]x\ge -7[/tex] and now we have our domain in interval notation.
