Answer:

A. The remainder isn't 0 and, therefore, (y − 3) isn't a factor of (y4 + 2y2 − 4).

Step-by-step explanation:

Use the remainder theorem and the factor theorem to determine whether (y − 3) is a factor of (y^4 + 2y^2 − 4).

y-3 is a factor then y-3=0 so y= 3

Now we plug in 3 for y in the given expression (y^4 + 2y^2 − 4)

(3)^4 + 2(3)^2 − 4= 81 + 18 -4=95

Remainder is 95

The remainder is not 0, so (y-3) is not a factor of the given expression

the remainder isn't 0 and, therefore, (y − 3) isn't a factor of (y^4 + 2y^2 − 4).

Write the equation of the line that passes through (0, 3) and is parallel to the line 3x + 5y = 6.
Sunny_sXe [5.5K]
There's more ways than one to solve this, just as there's more ways than one to skin a cat.

Two paralle lines have the same slope, so the desired new line looks exactly like the given line 3x + 5y = 6, except that the constant, 6, is replaced by another value.

Write out 3x + 5y = c
Replace x with 0 and y with 3.  Then 3(0) + 5(3) = c, and c = 15.

Thus, the equation of the new, parallel, line is 3x + 5y = 15.

Use estimation to help you choose the correct answer.<br><br> 0.945 x 7.6 =
hoa [83]

Remark

The thing you must not do is write 7.182 as your answer. That is the exact answer found using a calculator.


What to do.

What you should do is multiply two rounded numbers together.

7.6 rounded is 8 roughly


0.945 is almost 1.


Your answer is 8*1 = 8 roughly. This skill is very handy when you are writing a test and you want to see if you've done the question correctly. It is easy to misplace a decimal or put in incorrect digits and this is a quick check on things like that.

Can someone please help ASAP
White raven [17]

Answer: 36

Step-by-step explanation:

Multiply -6 by itself six times, then divide 1 by -6 four times. Multiply the products. Then multiply -6 by itself one more time and you will get 36.

The top question is 1/4. There seems to be a small multiplaction symbol next to the fractions, I'm ignoring that. To get 1/4, I multiplied 2 by itself six times because of the exponent, to get 64. I did the same with the bottom, and recieved 256. 64/256 is 1/4.
