If x/a = 4, a/y = 6, a2 = 9 and ab2 = −8 then x + 2y = ?
select one:
a. −10
b. −15
c. −5
d. −13

-13

Step-by-step explanation:

We are given:

Since then has to be negative.

Solving therefore gives .

(Note: .)

and gives us:

.

Multiplying both sides by -3 gives: .

and gives us:

.

Multiplying both sides by gives: .

Divide both sides by 6 gives: .

Simplifying this gives us .

Now we are asked to find the numerical value for .

D.

  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.
