which of the options is a solution for the following system of inequalities
(2x+y>3 (x-y>1

(5,-2)
(0,5)
(0,0)
(0,-5)
​

Answers

Answer 1

Answer:

(5, - 2)

Step-by-step explanation:

2x+y>3

x-y>1

2x + y > 3 - - - - (1)

x - y > 1 - - - (2)

Using trial and error method :

Using :

(5,-2)

2x + y > 3

2(5) + (-2) > 3

10 - 2 > 3

8 > 3 (true)

x - y > 1

5 - (-2) >1

5 + 2 > 1

7 > 1 (True)

For 0,5

2x + y > 3

2(0) + (5) > 3

0 + 5 > 3

5 > 3 (true)

x - y > 1

0 - (5) >1

-5 > 1

--5 > 1 (false)

Also, all other options do not hold true for bitb inequality statements, hence answer is (5, - 2)

Answers

The answer is C. The slope formula, y2-y1 over x2-x1, which can be remembered as rise over run, can be used to solve. The y2 is 7 as it is the second y and then 1, the first y, is subtracted from it. 7-1=6. After this, you find the second x which is 3, and subtract -6 from it, meaning that you add it as you are subtracting a negative and they cancel out. You now have 3-(-6), or 3+6 on the bottom and 7-1 on the top. 7-1=6 and 3+6=9. The answer is the 6/9 and can be simplified down to 2/3 because of their shared greatest common factor, 3. Hope this helps.

Find three solution's to the linear equation 4x+y=20 using a table​

Answers

Answer:

(-2, 28)

(-1, 24)

(0, 20)

Step-by-step explanation:

You can plug any numbers in for x, and solve for y.

Example: 4(-2) + y =20     multiply 4 and -2

                   -8 + y = 20     add 8 to both sides

                          y = 28

You can then do this for the rest of the numbers. Here is a table below:

Answers

Answer:

VA

Step-by-step explanation:

Angle VYA = 180-94-46 = 40 degrees.

Know that the side length opposite the smallest angle has the smallest length.

VY and VA are the two smallest, but 40 < 46, therefore VA is the shortest length.

Short (and not very rigorous) proof:

The law of sines says that sinA/a = sinB/b = sinC/c, where x is the side opposite the angle X

sin46/YV = sin40/VA

sin46 > sin40, therefore YV > VA.

B. x + 8


C. 2x + 5


D. x + 15

Answers

It would be A. 2x+15
Because you use the distributive property which equals 6x+15-4x
Then you add like terms so 6x-4x=2x soo 2x+15

Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a sting of light around. what length of lights should he buy?

Answers

Answer:

78 feet

Step-by-step explanation:

assuming it's the perimeter

25 + 25 + 14 + 14 = 78

The length of the string of the lights is 78 feet.

What is the perimeter of the rectangle?

P = 2(l + w), where 'l' is the length of the rectangle and  w is the width of the rectangle

For given example,

Len has a rectangular wooden deck that measures 14 feet by 25 feet that he wants to put a string of light around.

The length of the string of the lights = the perimeter of the rectangular wooden deck

Here, length of the deck (l) = 25 ft.

width of the deck (w) = 14 ft.

Using the formula of the perimeter of the rectangle,

⇒ P = 2 × (l + w)

⇒ P = 2 × (25 + 14)

⇒ P = 2 × 39

⇒ P = 78 ft.

The perimeter of the rectangular wooden deck is 78 feet.

Therefore, the length of the string of the lights is 78 feet.

Answer:

[tex]\frac{4}{3x-4}[/tex]

Step-by-step explanation:

The first thing we do to solve this is factor is completley

You can factor out a 4 from the numerator and get

4(3x+4)

The denominator is a  difference of squares which means that

(x^2-y^2)=(x-y)(x+y)

which means that 9x^2-16=

(3x-4)(3x+4)

Put these together and get

[tex]\frac{4(3x+4)}{(3x-4)*(3x+4)}[/tex]

The 3x+4 cancels out and we get left with
