Answer:
Step-by-step explanation:
box A has a 1 out of every 4 chance to get grape
but Bis one of about every 2 so the chance of getting a grape lolipop or skittle is 1/5 i think
We have [(3k)x(k-1)x(k+1)]/[3k^3x(k+1)] = (k-1)/k^2;
Y = 3x - 2
I assume this is what they mean;
3(1)- 2 = 1 for <span><span>x = 1
</span>Fill in the x's with the following numbers. so first... (x = 2)
</span>y = 3x - 2
3(2) - 2
multiply 3 and 2 and then minus 2
which equals 4 all together
y=4
therefore;
3(2) - 2 = 4
For x = 3
Fill in the x with 3 in the equation
3x - 2 = y
3(3) - 2 = y
9 - 2 = y
equals 7
so...
3(3) - 2 = 7
Do the same rule with number 4 :)
Let me know if it's different from what you're learning
16x - 5y = -33 First, you subtract 16x from both sides of the
<u>-16x -16x </u> equation
<u>-5y</u> = <u>-16x -33</u> Next, you divide both sides of the equation by -5 to
-5 -5 make "y =" form
y = 16/5x + 33/5
