2a-5b

= 1/2

3a+2b

find a/b

a/b = 12

Step-by-step explanation:

2a -5b          1

=

3a+2b             2

We can use cross products to get in the form of a /b

2(2a-5b) = 1(3a+2b)

Distribute

4a -10b=3a+2b

Get the a terms on the left and the b terms on the right

Subtract 3a from each side

4a-3a -10b=3a-3a+2b

a - 10b = 2b

Add 10b to each side

a-10b +10b = 2b+10b

a = 12 b

Divide each side by b

a/b = 12b/b

a/b = 12

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
