To add vectors, simply add the first coordinates from each and then add the second coordinates from each.  In other words, add the i terms together and then add the j terms together.  So u + v = <0, 2>.

Which is the best description for the graph below?<br><br> A graph decreases from (0, 3) to (9, 0).
AURORKA [14]

Answer:

Step-by-step explanation:

As we move from (0, 3) to (9, 0), we see x increasing by 9.  This is the 'run.'

At the same time, we see y decreasing by 3.  This is the 'rise.'

The slope of this line (graph) is m = rise / run = -3/9, or m = -1/3

Since we witness a decrease in y as we move from the first point to the second, we immediately suspect that the slope is negative.

Find the GCF 0f 12 and 18
melisa1 [442]

Answer:

  6

Step-by-step explanation:

Using Euclid's algorithm, we divide the larger by the smaller. If the remainder is zero, the divisor is the GCF. Otherwise, we replace the larger with the remainder and repeat.

  18 ÷ 12 = 1 r 6

  12 ÷ 6 = 2 r 0 . . . . the GCF is 6

__

You can also factor the numbers and see what the common factors are.

  18 = 2·3·3

  12 = 2·2·3

The common factors are 2·3 = 6.

In the factorizations, we see 2 to powers of 1 and 2, and we see 3 to powers of 1 and 2. The GCF is the product of the common factors to their lowest powers: (2^1)(3^1) = (2)(3) = 6

What multiplies to be 560 and adds to 9
Diano4ka-milaya [45]

There are no real numbers that can do that job.

There's a pair of complex numbers that can do it.
They are

         4.5 + i23.23
and
         4.5 - i23.23 .

     ' i ' = the imaginary unit = √(-1)

Question: Ned took a test with 25 questions. He lost 4 points for each of the 6 questions he got wrong and earned an additional
Dima020 [189]
Your thoughts are correct; Ned loses 14 points overall.

The reason the correctly answered questions do not factor into the answer is because that is not what the question is asking. Correct answers are not even mentioned :)
