Mathematics

Answer:

x = \frac{3}{2}y + 20

[Given]

4x - 6y = 20

[Add 6y to both sides of the equation]

4x = 6y + 20

[Divide both sides of the equation by 4]

x = \frac{6}{4}y + 20

[Simplify \frac{6}{4}, both 6 and 4 are divisible by 2]

x = \frac{3}{2}y + 20

Coordinate Help?
Vsevolod [243]
Coordinates of P = (6, -4)

Now, Transformation occurs in Horizontal direction, so x-ccordinate will change in the transformation.

x-coordinate = 6 - 12 = -6

In short, Your Answer would be: Option 3) (-6, -4)

Hope this helps!

Given the lengths of two sides of a triangle, find the range for the length of the third side. Write an inequality.
djverab [1.8K]

Answer:

| a - b | < length of third side < a + b

Step-by-step explanation:

Visualize the two given sides of the triangle (let's call then a and b), joined at the vertex of the triangle, and forming an angle. We can join the other free end of these two segments, with another segment whose length would vary according to how tiny or large the angle is. We can spread the aperture of the angle they form as much as we can just below  (not reaching this angle measure, because in such case, there will be no triangle of tangible area. In such case, the length of the joining segment will be limited by the addition of the two sides:

length of third side < a + b

In the case the aperture of the angle formed by the two given sides is diminished as much as possible to still form a measurable triangle, the angle has to be just larger than zero, and in such case, the segment joining the other to ends of a and b would be just larger than the absolute value of the difference between a and b:

length third side > | a - b|

These are the two extreme cases, and the length of the third side must be within these limits.

Which situation can be represented by 80x &gt; 150 + 50x?
V125BC [204]

Answer:

All numbers greater than 5, i.e., x>5 .

Step-by-step explanation:

The given inequality is  

80x>150+50x

Isolate variable terms on one side to find the solution.

Subtract  50x from both sides.

80x-50x>150+50x-50x

30x>150

Divide both sides by 30.

\dfrac{30x}{30}>\dfrac{150}{30}

x>5

It means, all the numbers which are greater than 5, are the solutions of the given inequality and 5 is not included in the solution set.

Suppose your​ friend's parents invest $15,000 in an account paying 6% compounded annually. What will the balance be after 9 ​yea
EleoNora [17]

Answer:

$25342.18

Step-by-step explanation:

Suppose my friend's parents invest $15000 in an account paying 6% compound interest which is compounded annually.

So, we have to calculate the balance that will become after 9 years i.e. the maturity amount after 9 years.

Now, using the formula of compound interest we get the sum as

S = 15000(1 + \frac{6}{100})^{9} = 25342.18 dollars (Approximate)

Label L, U, N, A with the correct angles. please help! (NO BOTS!)
Katyanochek1 [597]

Answer:

L= 126 degrees, U= 66 degrees, N= 48 degrees, A= 54 degrees

Step-by-step explanation:

The magic number is 180, that is when all angles form a strait line. So, in order to solve for each angle, you have to add and subtract a little. Some of the angles are the same degree as others because they are equivalent to their opposite angle. Hope that helps :)

P.S. I took geometry over two years ago so I know my stuff lol, I'm 100% sure. Cheers!
