The correct answers are:

The first system matches with (-4, 5);
The second system matches with (2, 2); 
The third system matches with (-1, -3);
The fourth system matches with (3, 4);
The fifth system matches with (2, -1); and 
The sixth system matches with (-5, 6).

Explanation:

The sixth system is the easiest one to find.  We are given the value of x and the value of y in the equations: x=-5 and y=6.

For all other systems, we must solve the system.  For the first system:
[tex] \left \{ {{2x-y=-13} \atop {y=x+9}} \right. [/tex]

Since we have the y-variable isolated in the second equation, we will use substitution.  We substitute this value in place of y in the first equation:
2x-y=-13
2x-(x+9)=-13

Distributing the subtraction sign,
2x-x-9=-13

Combining like terms:
x-9=-13

Add 9 to each side:
x-9+9=-13+9
x=-4

Substitute this into the second equation:
y=x+9
y=-4+9
y=5

The coordinates (-4, 5) represent the solution point.

For the second system:
[tex] \left \{ {{3x+2y=10} \atop {6x-y=10}} \right. [/tex]

We can make the coefficients of x the same and use elimination.  To do this, we will multiply the first equation by 2:
[tex] \left \{ {{2(3x+2y=10)} \atop {6x-y=10}} \right. \\ \\ \left \{ {{6x+4y=20} 
\atop {6x-y=10}} \right. [/tex]

Since the coefficients of x are now the same, we can cancel it.  They are both positive, so we subtract:
[tex] \left \{ {{6x+4y=20} \atop {-(6x-y=10)}} \right. \\ \\5y=10[/tex]

Divide both sides by 5:
5y/5=10/5
y=2

Substitute this into the second equation
6x-y=10
6x-2=10

Add 2 to each side:
6x-2+2=10+2
6x=12

Divide both sides by 6:
6x/6 = 12/6
x=2

The coordinates (2, 2) represent the solution to this system.

For the third system:
[tex] \left \{ {{4x-3y=5} \atop {3x+2y=-9}} \right. [/tex]

We can make the coefficients of x the same by multiplying the first equation by 3 and the second by 4:
[tex] \left \{ {{3(4x-3y=5)} \atop {4(3x+2y=-9)}} \right. \\ \\ \left \{ {{12x-9y=15} \atop {12x+8y=-36}} \right. [/tex]

Since the coefficients of x are the same, we can cancel them.  Since they are both positive, we will subtract:
[tex] \left \{ {{12x-9y=15} \atop {-(12x+8y=-36)}} \right. \\ \\-17y=51[/tex]

Divide both sides by -17:
-17y/-17 = 51/-17
y=-3

Substitute this into the first equation:
4x-3y=5
4x-3(-3)=5
4x--9=5
4x+9=5

Subtract 9 from each side:
4x+9-9=5-9
4x=-4

Divide each side by 4:
4x/4 = -4/4
x=-1

The coordinates (-1, -3) represent the solution of the third system..

For the fourth system:
[tex] \left \{ {{x+y=7} \atop {x-y=-1}} \right. [/tex]

Since the coordinates of x are the same and both are positive, we can cancel x by subtracting:
[tex] \left \{ {{x+y=7} \atop {-(x-y=-1)}} \right. \\ \\2y=8[/tex]

Divide both sides by 2:
2y/2 = 8/2
y=4

Substitute this into the first equation
x+y=7
x+4=7

Subtract 4 from each side:
x+4-4=7-4
x=3

The coordinates (3, 4) represent the solution to the fourth system.

For the fifth system:
[tex] \left \{ {{y=3x-7} \atop {y=2x-5}} \right. [/tex]

Since y is isolated in each equation, we can set them equation to each other:
3x-7=2x-5

Subtract 2x from each side:
3x-7-2x=2x-5-2x
x-7=-5

Add 7 to each side:
x-7+7=-5+7
x=2

Substitute this into the first equation:
y=3x-7
y=3(2)-7
y=6-7
y=-1

The coordinates (2, -1) represent the solution to the fifth system.

Have a brainy day!

the string, that supports the stairs, makes an angle of 50° with the floor. It reaches 3.2 m up the wall. How far is the base od the stringer from the wall?

Answers

Greetings,

The best way to do these problems is to draw a picture. In this case, you would have a right triangle. I included a picture.

If we use the 54 degree angles as our angle of reference, we are dealing with the opposite side and adjacent side. This makes it a tangent ratio.

We can set up the equation:
tan 54 = 3.2/x
1.19 = 3.2/x    Cross Multiply
1.19x = 3.2     Divide by 1.19
x = 2.69

The base of the stringer is 2.69 m from the wall.

I hope this helps,
MrEQ
Final answer:

We use trigonometry to find the distance from the base of the string to the wall. The cosine of an angle in a right triangle is defined as the adjacent side length divided by the hypotenuse length. You can plug the given values into the rearranged formula and solve it.

Explanation:

The question is asking about the distance from the base of the string (the part that touches the floor) to the wall. This is a typical trigonometry problem. We know that the string forms an angle of 50° with the floor and that it stretches up to 3.2 m on the wall. Given these values, we can use the cosine function to find the distance between the base of the string and the wall.

The cosine of an angle in a right triangle is defined as the adjacent side length divided by the length of the hypotenuse. In our case, you can think of the 3.2 m wall height as the 'adjacent' and the string length as the 'hypotenuse'. So, we can rearrange this relationship to solve for the base, or 'hypotenuse', of the triangle:

Length of string (hypotenuse) = Adjacent side / cos(angle)

Plugging in the values we know:

Length of string = 3.2 m / cos(50°)

After that, you can plug the numbers into a calculator to find the value in meters of the distance from the base of the string to the wall.

A farmer in china discovers a mammal hide that contains 54% of its original amount of c-14. Find the age of the mammal hide to the nearest year

Answers

Final answer:

The age of the mammal hide can be determined by using carbon-14 dating. By comparing the remaining amount of carbon-14 to the initial amount and knowing the half-life of carbon-14, the age of the hide can be calculated. In this case, the hide is approximately 778 years old.

Explanation:

The age of the mammal hide can be determined using carbon-14 dating. Carbon-14 (or C-14) is an isotope that is present in all living organisms. When an organism dies, the amount of C-14 in its remains begins to decay.

Based on the information provided, the mammal hide contains 54% of its original amount of C-14. Knowing that the half-life of C-14 is 5,730 years, we can calculate the age of the hide.

To do this, we can set up the following equation: Remaining amount of C-14 = Initial amount of C-14 × (0.5)^(number of half-lives)

Since the hide contains 54% of its original amount of C-14, the remaining amount is 0.54 times the initial amount.

By substituting the known values into the equation, we can solve for the number of half-lives:

0.54 × Initial amount of C-14 = Initial amount of C-14 × (0.5)^(number of half-lives)

Dividing both sides of the equation by the initial amount of C-14 and taking the logarithm of both sides, we can find the number of half-lives:

ln(0.54) = number of half-lives × ln(0.5)

Using a logarithmic calculator, we find that the number of half-lives is approximately 0.136.

Since each half-life spans 5,730 years, we can calculate the age of the hide:

Age of hide = Number of half-lives × Half-life duration

Age of hide = 0.136 × 5,730 years

Therefore, the age of the mammal hide is approximately 778 years.

Marvin lives in Stormwind City and works as an engineer in the city of Ironforge. In the morning, he has 3 transportation options (teleport, ride a dragon, or walk) to work, and in the evening he has the same 3 choices for his trip home. If Marvin randomly chooses his method of travel in the morning and in the evening, what is the probability that he teleports at least once per day?

Answers

Answer:

The probability is [tex]P=\frac{5}{9}[/tex]

Step-by-step explanation:

Marvin has to randomly choose between 3 transport options.

Since the choice is random, then the probability of choosing any of the three options is the same.

The probability of teleportation in the first attempt is:

[tex]P_t = \frac{1}{3}[/tex]

So, the probability that you do not teleport is

[tex]q = 1-p\\\\q = 1-\frac{1}{3}\\\\q = \frac{2}{3}[/tex]

The probability that Marvin does not teleport when going to work and Marvin does not teleport when he returns from work is:

[tex]P = \frac{2}{3} * \frac{2}{3}\\\\P = \frac{4}{9}.[/tex]

Therefore the probability of teleportation at least once is:

[tex]P= 1-\frac{4}{9}\\\\P = \frac{5}{9}[/tex]

The value of the hypotenuse x is equal to 12 units.

What is the Pythagorean theorem?

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

Use the Pythagorean theorem for this. (a^2+b^2=c^2)

a=9, b=12, c=x

The value of x will be calculated as,

a² + b² = c²
