Answer:

x=5

y=0

Step-by-step explanation:

KL = JM

3x-y = 15

and JK = LM

4x -4y = 20

Divide this equation by 4

x-y= 5

Multiply by -1

-x+y =-5

Add this to the first equation

3x-y = 15

-x+y =-5

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

2x = 10

Divide by 2

2x/2 = 10/2

x =5

x-y = 5

5-y = 5

-y = 0

y =0

Answer:

x=5,y=0

Step-by-step explanation:

KL=JM [Opposite sides of rectangle are equal]

3x-y=15-> eq 1

JK=LM

4x-4y=20

=>4(x-y)=20

=>x-y=5-> eq 2

From eq 1 and 2,

3x-y=15

x-y=5

=>2x=10

=>x=5

x-y=5

y=x-5

=>y=5-5

=>y=0

Suppose g(m) varies inversely with M and g (m) = 3.5 when m = 10.

mojhsa [17]

Answer:

m =7.

Step-by-step explanation:

Let the constant number = k.

g(m) = k/m,

3.5 = k/10,

k = 35.

Thus, when g(m) = 5 = 35/m, m = 7.

Using the quadratic formula to solve x2 + 20 = 2x, what are the values of x?

jeka94

by Quadratic formula , $x^2 + 20 = 2x$ , values of x are $x = 1 \pm (1)i\sqrt{19}}$ . None of mentioned options are correct according to question!

Step-by-step explanation:

Here we have , expression x2 + 20 = 2x or , $x^2 + 20 = 2x$ .

We know that Quadratic formula is :

$x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$

$x^2 + 20 = 2x$

⇒ $x^2-2x+20=0$

$a=1\\b=-2\\c=20$

Putting this value in equation $x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$ :

⇒ $x = \frac{-b \pm \sqrt{b^{2}-4ac}}{2a}$

⇒ $x = \frac{-(-2) \pm \sqrt{(-2)^{2}-4(1)(20)}}{2(1)}$

⇒ $x = \frac{2 \pm \sqrt{4-80}}{2}$

⇒ $x = (\frac{2 \pm 2i\sqrt{19}}{2})$

⇒ $x = 1 \pm (1)i\sqrt{19}}$

Therefore , by Quadratic formula , $x^2 + 20 = 2x$ , values of x are $x = 1 \pm (1)i\sqrt{19}}$ . None of mentioned options are correct according to question!
