Step-by-step explanation:

Answer:

x = 6

y = 7

Step-by-step explanation:

Here, (10x - 8y = 4) and (- 5x + 3y = - 9) are two given equation

Now, Name the equation

10x - 8y = 4

take 2 as common we get

2(5x - 4y = 2)

5x - 4y = 2 ...(1)

- 5x + 3y = - 9 ...(2)

Now, Subtract (1) from (2)

5x - 4y = 2

- 5x + 3y = - 9

————————

- y = - 7

y = 7

Now, Put the value of y in equation (1) we get

5x - 4y = 2

5x - 4(7) = 2

5x - 28 = 2

5x = 28 + 2

5x = 30

x = 30÷5

x = 6

Thus, The value of x is 6 and y is 7

FOR VERIFICATION ONLY:

5x - 4y = 2

5(6) - 4(7) = 2

30 - 28 = 2

2 = 2

- 5x + 3y = - 9

- 5(6) + 3(7) = - 9

- 30 + 21 = - 9

- 9 = - 9

Hence, L.H.S = R.H.S

Answer:

x = 17

Step-by-step explanation:

We are going to call the missing angle in triangle EDC, "y"

x+y+100=4x+49+y

Eliminate the "y" on both sides

x+100=4x+49

move the x by subtracting the x on the left from the right

100= 3x +49

Move the numbers by subtracting 49 from 100

51 = 3x

Divide both sides by 3

17=x

Answer:

x=17

Step-by-step explanation:

Hello! There are a few important pieces of information you need to keep in mind before trying to solve this problem:

Now that we know these two pieces of information, we can begin to set up our problem. Because the angles in a triangle always add up to 180, we can set up the problem as follows:

x + 100° + ∠DCE = 4x + 49° + ∠ACB

Now this is where the vertical angles come in. Angles ∠DCE and ∠ACB are vertical, which makes them congruent. Since they are the same value, we can subtract them from either side of the equation. (NOTE: We can only do this because they are the same value. Subtracting angles of different values will mess up your answer!!!)

Now, we have the same problem in much simpler terms. We can now simplify it in order to get x.

4x + 49 = x + 100 (subtract 49 from both sides)

4x = x + 51 (subtract x from both sides)

3x = 51 (divide both sides by 3)

x = 17 (FINAL ANSWER)

Answer:

m‹1 = 125°

m‹2 = 55°

Step-by-step explanation:

Corresponding angles, a linear pair, and a vertical angle.

This applies because there is a transversal (because it forms angles between the two lines) which cuts between two parallel lines (indicated by the red mark).

Answer: 4 feet

Step-by-step explanation:

In order to determine the length of side, we need to use what is called the Pythagorean theorem, which states: a² + b² = c² The a and b in this equation are both of the sides of the triangle that we call legs. (I have attached a picture for reference if you do not know what sides I am referring to). The c in this equation refers to the hypotenuse of the triangle. (Again, please refer to the attached photo).

So now, we need to plug in the information we already know into this equation. The height of the ramp will be our a and the distance from the box will be our b. We can see that the hypotenuse (c) is labeled as 5, so we can fill in that information in our equation.

a²+b²=5² (simplify by squaring the 5)

a²+b²=25

Next, we know that the height of the box is 3 feet, which let's us know that our a is 3. Let's plug this new information in.

3²+b²=25 (simplify by squaring the 3)

9+b²=25 (simplify by substracting the 9 from both sides)

b²=16

Hey! Now our equation looks much simpler! Now, all we need to do it square root both of the sides in order to get b by its self.

b²=16

√b² = b

√16 = 4

Final answer: b = 4

I truly hoped this explanation helped! If you feel you still need a bit of help, David May explains the Pythagorean theorem very well in his video titled, "Find The Hypotenuse Using Pythagorean Theorem | Dave May Teaches" if you would like to check it out. Take care! :)

Answer:

Step-by-step explanation:

7). x + y = 4 ⇒ y = 4 - x -----> xy = - 96

x(4 - x) = - 96 ⇔ x² - 4x - 96 = 0

D = ( - 4)² - 4(1)(- 96) = 400 = (20)²

[tex]x_{1}[/tex] = (- ( - 4) - 20) ÷ 2(1) = - 8

[tex]x_{2}[/tex] = ( - ( - 4) + 20) ÷ 2 = 12

Numbers are - 8 and 12

8). It's your turn now. You can do it

9). x² - 5x + 3 = 0

0 < [tex]x_{1}[/tex] < 1

4 < [tex]x_{2}[/tex] < 5

10). - x² + 3x + 1 = 0

-1 < [tex]x_{1}[/tex] < 0

3 < [tex]x_{2}[/tex] < 4

11). x² + 2x - 2 = 0

- 3 < [tex]x_{1}[/tex] < - 2

0 < [tex]x_{2}[/tex] < 1

the domain of a sine function is from negative to positive infinity. The domain is written as (-∞,∞) in interval notion. It it the same thing as the domain is all real numbers.

The sides this polygon have is 5 sides.

A polygon is a closed figure made up of three or more line segments connected end to end.

Any closed figure made by 4 line segments joined end to end in series is called a quadrilateral.

We are given  shown in the illustration, starfish that has the shape of a pentagon.

Since a pentagon is a polygon that has 5 sides.

Therefore, the sides this polygon have is 5 sides.
