The following table shows a proportional relationship between x and y.

RUDIKE [14]

Answer:

Assume x is directly proportional to y :

$y \: \alpha \: x \\ y = kx$

when y is 9, x is 2:

substitute to find value of k :

$9 = (k \times 2) \\ k = \frac{9}{2}$

Therefore, equation is:

${ \boxed{ \boxed{2y = 9 x}}}$

2x = 4y + 8, x - 2y = 4

Evgen [1.6K]

Answer: x = 8, y = 2, coordinates (8,2)

Step-by-step explanation:

2x = 4y + 8 (divide by 2 to get value of x)

x = 2y + 4

(now substitute x into the second equation to find value of y)

2y + 4 - 2y = 4

2y - 2y = 4 - 4 (divide by 2 to get value of y)

y - y = 2 - 2

y = 2

Now plug in value of "y" to get value of "x".

x - 2(2) = 4

x - 4 = 4

x = 8

Coordinates (8,2)

What is the Greatest common factor of 18x^2 and 36x

loris [4]

For this case we have that by definition, the Greatest Common Factor or GFC of two or more numbers, is the largest number that divides them without leaving residue.

So:

We look for the factors of 18 and 36:

18: 1,2,3,6,9,18

36: 1, 2,3,4, 6,9,18 ...

Thus, the GFC of both numbers is 18.

Then, the GFC of $18x ^ 2$ and $36x$ is:

$18x$

Answer:

$18x$
