You gather the like terms together.
if you have -3y +2x +6w -4 + 3y -5x +2w
you put the like terms together
so for the term y:
you have -3y +3y = 0
for x:
2x - 5x = -2x
for w:
6w + 2w = +8w
and you also had -4. if you put them together you get
0 -2x +8w -4
which is
-2x +8w -4
hope this helps
For this case we must complete squares:
We add the square of half the coefficient of the term "x",
on both sides of the equation:
According to the perfect square trinomial we have:
Rewriting the expression we have:
ANswer:
Answer: False. From 24 to 12 is 2 divided but 6 to 12 is 2 multiplied. Hope this helps :)
Step-by-step explanation:
We would need to look over the z table to find the area under the standard normal distribution curve to the left of z = 1.04. Then we'll subtract it from 1 to get the proportion of a normal distribution corresponding to z scores greater than 1.04.
By looking at the z table, we can see that the area to the left of z = 1.04 is 0.8508. So the proportion of a normal distribution to the right of z = 1.04 is 1 – 0.8508 = 0.1492.
The answer is 0.1492.
