Answer:

f(x) = - 3x + 4

Step-by-step explanation:

Change the subject of the function to y, that is

Given

9x + 3y = 12 ( subtract 9x from both sides )

3y = - 9x + 12 ( divide all terms by 3 )

y = - 3x + 4, that is

f(x) = - 3x + 4

Grace [21]

Answer:

\frac{1}{400} or 0.0025 0r 0.25%

Step-by-step explanation:

There are three categories that will get a prize

1) First place = 1 person

2) Second place = 5 persons

3) Third place = 20 persons

A total of 26 people will get prizes.

However, we want to determine your chance to win one of the second place prizes

There are 5 prizes in second place

This means out of a total of 2000 people, you could be among the 5

i.e 5 out of 2000

This is \frac{5}{2000} = \frac{1}{400} = 0.0025

This means you have a chance of 1 out of 400

= 0.25%

Suppose y varies directly with x. If y = –20 when x = 2, find y when x = 14
Alona [7]

Answer:

y = -140

Step-by-step explanation:

Y varies directly with x

y = kx

We know y = -20 when x =2, we can solve for k

-20 = k*2

Divide each side by 2

-20/2= 2k/2

-10 =k

y = -10x

Now we want to find y when x = 14

y = -10 *14

y = -140
