Step-by-step explanation:

common sense

This is a system of three equations with two unknowns, x and y. To solve it, we can use the method of elimination. First, we can eliminate y by subtracting the first equation from the second equation:

x^2-2y=3 - (x-2y=3) => x^2-x=0

Then we can factor the resulting equation and find the values of x:

x^2-x=0 => x(x-1)=0 => x=0 or x=1

Next, we can substitute these values of x into any of the original equations and find the corresponding values of y. For example, using the first equation:

x-2y=3 => 0-2y=3 => y=-3/2 when x=0 x-2y=3 => 1-2y=3 => y=-1 when x=1

Finally, we can substitute these values of x and y into the expression x2y-2xy2 and evaluate it:

x2y-2xy2 => 02(-3/2)-2(0)(-3/2)2 => 0 when x=0 and y=-3/2 x2y-2xy2 => 12(-1)-2(1)(-1)2 => -3 when x=1 and y=-1

Therefore, the value of x2y-2xy2 can be either 0 or -3 depending on the values of x and y.

Answer:

b)

Step-by-step explanation:

Supplementary angles add up to 180 degrees, so the answer must be b).  Let's check the math:

77 + (5x + 18) = 180

-77                    -77

(5x + 18) = 103  --> here we already know this is correct, as the problem tells us that angle H is equal to this equation, (5x + 18), and we know that it is also equal to 103.

Answer:

x = 20/3

Step-by-step explanation:

When 10 is subtracted from 3 times the number and the number is divided by 2, what is the number?     --->        3 ( x / 2) - 10 = 0

3 ( x / 2) - 10 = 0

      3( x / 2 ) = 10

          3x / 2 = 10

               3x = 10 * 2

               3x = 20

                 x = 20/3

Answer:

  A, B, E

Step-by-step explanation:

When you put x=1 into the cost formula for store A, you find one eraser costs $0.75. (Makes statement A true.)

When you look up the cost of 1 eraser on the graph, you see it is $0.25 at store B. (Makes statement B true.)

Since statements A and B are true, statement E is true, and statements C and D are false.

The true statements are A, B, E.

The correct answer is A. Conic projection.

A conic projection is a type of map projection created by projecting the surface of a globe onto a cone. The cone is then unrolled and flattened to create a two-dimensional map. Conic projections are best for mapping small areas, such as individual countries or states. They are also good for mapping areas that are located near the equator.

Conic projections show the size and shape of continents accurately, but they distort water areas. This is because the cone is tangent to the globe at one point, and the further away from that point you get, the more distortion there is.

Mercator projection is a cylindrical map projection presented by Flemish geographer and cartographer Gerardus Mercator in 1569. It became the standard map projection for navigation because it is unique in representing north as up and south as down everywhere while preserving local directions and shapes. The map is thereby conformal. As a side effect, the Mercator projection inflates the size of objects away from the equator. This inflation is very small near the equator but accelerates with increasing latitude to become infinite at the poles.

Robinson projection is a map projection presented by American cartographer Arthur H. Robinson in 1963. It is a compromise projection that attempts to balance the distortions of area, shape, and distance. The Robinson projection is neither conformal nor equal-area, but it is pseudocylindrical, which means that the meridians are straight lines and the parallels are circles.

Interrupted projection is a type of map projection that is interrupted at regular intervals. This is done to reduce the distortion of the map. The most common type of interrupted projection is the Mercator projection, which is interrupted at the equator and the prime meridian

Step-by-step explanation:

Let's assume the amount Mackey initially invested in the 6% account is x dollars.

According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.

The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.

The total interest earned in the year is given as $737.50, so we can set up the equation:

0.06x + 0.085(x + $1000) = $737.50

Simplifying the equation:

0.06x + 0.085x + 0.085($1000) = $737.50

Combining like terms:

0.145x + $85 = $737.50

Subtracting $85 from both sides:

0.145x = $737.50 - $85

0.145x = $652.50

Dividing both sides by 0.145:

x = $652.50 / 0.145

x ≈ $4500

Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.

$4500

$4500

$4500

$4500

Answer:

D) None of the above

Step-by-step explanation:

Let's use process of elimination!

A) Vertical angles are opposite angles formed by two intersecting lines. These two are adjacent, therefore rendering this statement false.

B) Complementary angles are two adjacent angles that add up to 90 degrees. There is no proof that m∠a+∠b=90°, therefore this statement is false.

C) Supplementary angles are two adjacent angles that add up to 180 degrees. Assuming A∈ED, this statement is false as well.

D) None of the answers above are correct.

A. |–4.8| > |2.5|

Step-by-step explanation:

When, you compare the distance between stuff, you always compare the absolute value of each thing. And even this equation does not ask for the distance between stuff, it still does require you to compare it with absolute value. The negative sign is only their because they are digging up the ground and not adding to the ground. However, when comparing it, we want to find what is deeper, so we use absolute value making it both positive to compare it fairly. However, if it asked which one was less deep you will use the negative signs. But based on this situation, you don't need to.

Answer:y=x+2/5

Step-by-step explanation:

To solutions for the questions on two quantities are;

1. Time (in hours) and the miles of road paint. The independent quantity is time (t), and the dependent quantity is miles of road painted (m). t for time and m for miles. The equation that relates these two quantities is: m = 9.5 + 0.25t

2. The rate at which the painting crew is painting the road, which is 0.25 mile per hour. This means that for every hour the crew works, they paint 0.25 mile of the road.

3. 10 miles

4. 10 more hours to complete half of the job.

5. quantities                            Time               Miles

                                                  -36                   0

1. The equation m = 9.5 + 0.25t represents a linear relationship between two variables, m and t.

The equation indicates that the crew has already painted 9.5 miles before they start painting at the rate of 0.25 mile per hour. As the crew continues to work (increasing t), the total miles painted (m) increases by 0.25 miles for every additional hour they work. The equation helps to determine the total miles painted by the crew after a certain amount of time.

If the crew works for another 2 hours, we can find the total miles they will complete using the equation:

m = 9.5 + 0.25(2)

m = 9.5 + 0.5

m = 10

The Department of Transportation in each state is responsible for the improvements and repairs of that state's roads. One important job is to repaint the road lines that have worn away or faded. A painting crew is painting a 24-mile stretch of road. They have already completed a total of 9.5 miles of the road. The crew has been painting at a rate of 0.25 mile per hour and continues to paint at the same rate.

1 Identify the two quantities that are changing in this situation, identify the independent and dependent quantities, and define the variables for these quantities. Then write an equation that relates the two quantities.

2 What is the unit rate of change in this situation? Explain.

3 How many total miles of the road will the crew complete if it works for another 2 hours?

4 How many more hours does the crew need to work to complete half of the job?
