Solve this system 2x-4y=14 3y+5x=9

Mathematics
1 answer:
anygoal [31]2 years ago
8 0

Answer:

x=3, y=-2

Step-by-step explanation:

If 2x-4y=14, then we know that 2x=14+4y.  This means that x=7+2y.  If we substitute this into the next equation we get: 3y+(35+10y)=9.  This means that we have 35+13y=9.  If we subtract 35 from both sides we get 13y=-26.  This means y=-2. If you subsitute this in the first equation, we have 2x--8=14.  -- means + so you do 2x+8=14.  This means that x=3.

btw this is my first answer so sorry if its bad.

A researcher gathered data on hours of video games played by school-aged children and young adults. She collected the following
antiseptic1488 [7]

Step-by-step explanation:

The complete frequency distribution table for the data has been attached to this response.

The frequency column contains values that are the number of times the given range of hours appear in the data. For example, numbers in the range 0 - 2 hours, appear <em>9</em> times in the data. Also, the numbers in the range 3 - 5 appear  <em>6</em> times. The same logic applies to other ranges.

The relative frequency column contains the ratio of the number of times the given range of hours appear in the data, to the total number of outcomes. The total number of outcomes is the sum of all the frequencies on the frequency column. This gives 38 as shown.

So, for example, to get the relative for the numbers in the range 0-2, divide their frequency (9) by the total outcome or frequency (38). i.e

9 / 38 = 0.24

Also, to get the relative for the numbers in the range 3-5, divide their frequency (6) by the total outcome or frequency (38). i.e

6 / 38 = 0.16

Do the same for the other ranges.
