Answer:

f(x) = - 3x + 4

Step-by-step explanation:

Note that y = f(x)

Given

9x + 3y = 12 ← rearrange making y the subject

Subtract 9x from both sides

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

y = - 3x + 4, that is

f(x) = - 3x + 4

21 marbles out of N are blue; probability of getting a blue one = 30%

MissTica

$Probability=\frac{desired}{total}$
$0.3=\frac{21}{N}$
$0.3N=21$
$N=\frac{21}{0.3}$
$N=70$

There are 70 total marbles.

Write an equation that represents the line. Use exact numbers.

Nastasia [14]

Answer:

Step-by-step explanation:

<em>(0;2)</em> and (4;5)

<em> (x1;y1)</em> ; (x2;y2)

y=mx+b

m=(y2-y1)/(x2-x1)

m=(5-2)/4-0)

m=3/4

y=mx+b=> 2=3/4 *0+b; => b=2

So, y=3x/4 +2
