Answer:

200 √17

Step-by-step explanation:

distance between two points (x,y) and (x',y')

D² = (x' - x)² + (y' - y)²

D² = (500 - (-300))² + (400 - 200)² = 640000 + 40000 = 680000

D = √680000 = √4 x 17 x 10000 = 200 √17

Solve the system by the substitution method.
Gemiola [76]

Answer:

(2,2)

Step-by-step explanation:

Given equations

x-3y=-4-------------------------------(1)

y=-3x+8.------------------------------(2)

Substitute 2 in 1. This means use the value of y in equation 1, to replace y

x-3(-3x+8)=-4------------------open brackets

x+9x-24=-4---------------------collect like terms

10x=-4+24

10x=20---------------------------divide by 10 both sides to get value of x

10x/10=20/10=2

x=2------------------------------use value of x in equation (2) to get value of y

y=-3x+8

y=-3(2)+8

y=-6+8=2

solutions

x=2, y=2

The mass of an ornament is m grams.
MArishka [77]

Given:

m is directly proportional to the cube of h.

m = 525 when h= 5.

To find:

The equation connecting m and h.

Solution:

m is directly proportional to the cube of h.

m\propto h

m=kh            ...(i)

Where, k is the constant of proportionality.

Putting m = 525 and h= 5, we get

525=k(5)

\dfrac{525}{5}=k

105=k

Putting k=105 in (i), we get

m=105h

Therefore, the required equation is m=105h.

Dont do QA <br> plzzzzzzzzzzzzzzzzzzzzzzzz
N76 [4]

Answer:

(a) x^2-2x=x \times (x+2) \\\\(b) 6x^2+12x=2\times 3 \times x \times ( x + 2) \\\\(c)  3x^3 - 9x=3\times x \times (x^2 -3) \\\\(d) 4x^2 +28 x^3 = 2 \times 2 \times x \times x \times ( 1+ 7x)

Step-by-step explanation:

To factorize, at first, do factorize all the terms then take the common terms out.

(a) x^2-2x

This can be written as

x^2-2x= x\times x + 2 \times x

Now, taking x commom from both the terms.

x^2-2x=x \times (x+2)

(b) 6x^2+12x

=2\times 3 \times x\times x + 2\times 2 \times 3 \times x

Now, taking 2\times 3\times x common from both the terms, we have

6x^2+12x=2\times 3 \times x \times ( x + 2)

This is the required factorization.

(c) 3x^3 - 9x \\\\

= 3 \times x \times x \times - 9\times x \\\\ 3x^3 - 9x=3\times x \times (x^2 -3)

This is the required factorization.

(d) 4x^2 +28 x^3

= 2 \times 2 \times x \times x + 2 \times 2 \times 7 \times x \times x \times x \\\\4x^2 +28 x^3 = 2 \times 2 \times x \times x \times ( 1+ 7x)

This is the required factorization.
