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

I’m sorry i can’t u

First step is to get rid of the square root. remember that a square root is the same as raising to the (1/2) power. see below: multiply exponents per exponent rules to get: remember you subtract exponents from the denominator and add exponents in the numerator so: simplify further: so a is the correct choice. if you don't understand this google exponent rules and it will you understand. look at the image results.
