Use elimination to solve the system of equations. 2x+y=4 and -4x-2y=8

Answers

Answer: No solution

Step-by-step explanation:

To use elimination method, we need to choose a variable to eliminate. Let's eliminate x. To eliminate x, the x coefficient in both equations must be the same, regardless of the sign. To do so, let's multiply the first equation by 2.

(2x+y=4)2

-4x-2y=8

-------------------------------------------------------------------------------------------------------------

4x+2y=8

-4x-2y=8

Let's add both equations together.

0=8

-------------------------------------------------------------------------------------------------------------

Now that we got this far, we can see that something is wrong. This normally doesn't happen. If you notice, the second equation is the first equation but multiplied by 2. Instead, let's rewrite each equation.

2x+y=4              [subtract both sides by 2x]

y=-2x+4

-4x-2y=8           [add both sides by 4x]

-2y=4x+8          [divide both sides by -2]

y=-2x-4

-------------------------------------------------------------------------------------------------------------

If you analyze both equations, you will see that they are parallel lines. We know this because the slopes are the same, but different y-intercept. from our knowledge of parallel lines, they NEVER touch or cross. This means there would be no solution at all.

A person becomes instagram famous when they have more that 5,000. Dmytryus currently has 2,000 followers. For every 500 likes a photo of his gets, he gains 20 followers. a.) what is the slope and what does it represent in this situation? b.) How many likes does Dmytryus need before he will become instagram famous? ANSWER THIS IS URGENT!!!!!

Answers

Answer:

a. 25/1, likes per follow b. 75,000 likes

Step-by-step explanation:

The slope is the likes per follow, which is 500/20 simplified to 25/1.  To find how many he needs for answer b, you first need to find how many more followers he needs, which is 3000.  You then multiply the number of likes per follow by the number of followers needed, 25x3000.  Dmytryus needs 75000 likes to become Instagram famous.

Use Similar triangles to calculate the height, h cm, of traingle ABE

Answers

Answer:

  24 cm

Step-by-step explanation:

Since the triangles are similar, their dimensions are proportional. The base DC is half the base AE, so we know the ratio of triangle heights is 1 : 2.

Then the bottom height (h) ratio to the overall height is ...

  h : 36 = 2 : (1+2) = 2 : 3 = 24 : 36

The height h is 24 cm.

What equation can Janet use to calculate the principal amount? (and please don't just answer try to solve it someone ripped me off, the last time i asked by just typing)

Answers

Answer:

t = [tex]\frac{l}{pr}[/tex]

Step-by-step explanation:

Formula or literal equation used to calculate the simple interest is,

l = prt

where 'l' = Simple interest

p = principle amount invested

r = rate of interest

t = time or duration of the investment

If we have to calculate the time of investment form the given formula,

l = prt

By the division property of equality,

[tex]\frac{l}{pr}=\frac{prt}{pr}[/tex]

[tex]t=\frac{l}{pr}[/tex]

Therefore, formula to be used is, [tex]t=\frac{l}{pr}[/tex]

make y the subject of the formula x=a-2by squared

Answers

Answer:

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Step-by-step explanation:

Given

x = a - 2by² ( subtract a from both sides )

x - a = - 2by² ( multiply through by - 1 to clear the leading negative )

a - x = 2by² ( divide both sides by 2b )

[tex]\frac{a-x}{2b}[/tex] = y² ( take the square root of both sides )

y = ± [tex]\sqrt{\frac{a-x}{2b} }[/tex]

Making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be:

[tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

Given the formula: [tex]x = a - 2by^2[/tex],

Required:

Making y the subject of the formula

This is done as shown below:

[tex]x = a - 2by^2[/tex]

Subtract a from both sides

[tex]x - a = - 2by^2[/tex]

Divide both sides by -2b

[tex]\frac{x - a}{-2b} = y^2[/tex]

Take the square root of both sides

[tex]\sqrt{\frac{x - a}{-2b}} = y\\\\\\\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

Therefore, making y the subject of the formula, [tex]x = a - 2by^2[/tex] , the answer would be:  [tex]\mathbf{y = \sqrt{\frac{x - a}{-2b}} }[/tex]

The border area will be the difference between pool+border and pool. The area of each rectangle is the product of its dimensions.

  (x+3)(x-2) -(x+2)(x+1) = (x^2 +x -6) -(x^2 +3x +2)

  = x^2(1 -1) +x(1 -3) +(-6 -2)
