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 term by 3 )
y = - 3x + 4, thus
f(x) = - 3x + 4
The answer is 3
5x = 16-1
5x = 15
x = 3
Which one I can help with anyone
-3x - 18 = 0
-3x = 18
x = -6
I believe ( i am not 100% certain) that the theoretical probability would be 1/2 or 300/600 and the experimental probability is 252/600, you may need to simplify that
