Y varies directly as x and y =18 when x=1/2 write an equation that relates y and x

Mathematics
1 answer:
marusya05 [52]3 years ago
6 0

Answer:

y = 36x

Step-by-step explanation:

Given that y varies directly as x, then the equation relating them is

y = kx ← k is the constant of variation

To find k use the condition y = 18 when x = \frac{1}{2}, thus

k = \frac{y}{x} = \frac{18}{\frac{1}{2} } = 36

y = 36x ← equation of variation

Synthetic Division <br> -2 | 1 2 -3 1
Tom [10]

Answer:

7

Step-by-step explanation:

I am assuming that the division problem looks like this:

-2|  1   2   -3   1

Going off that assumption, we will work this problem.  The first thing you always do in the execution of synthetic division is to bring down the first number.  Then multiply that number by the one "outside", which is -2, then put that number up under the next number in the line:

-2|  1   2   -3   1

        -2

    1

Now add the 2 and -2 and bring that down as a 0 and multiply the -2 times the 0:

-2|   1   2   -3   1

         -2    0

     1    0

Now add -3 and 0 to get -3 and multiply that -3 times the -2 and put the product up under the next numbe in line;

-2|   1   2   -3   1

          -2   0  6

     1     0   -3

Now add the 1 and the 6 to get the remainder:
