Given the equation 2x +4/3 y equals one and y -9/13 x=9 by what vector would you multiply the first equation so that combining the two equations would eliminate x
a -9/26
b 9/26
c 1/2
d -9/13

Option B

B.

Step-by-step explanation:

We have the following equations:

      (1)

         (2)

Let us call "a" the coefficient of the variable x in the first equation and call "b" the coefficient of the variable x in the second equation.

Then we must multiply the number "a" by a value z such that when adding the result is zero.

So

We solve the equation for z

The first equation must be multiplied by a value of

$450 is the answer.

step-by-step explanation:

30% of 450 = 135

450-135=315

so far i think you have the right thing going for you just remember soh cah toh

step-by-step explanation:

sine over hypotenuse

cosine   equals adjacent

tangent over hypotenuse
