Show how you know. Is (-4,6) a solution to this system? 3x+4y=12 y = -3/2x

step-by-step explanation:

just plug in each number for x and see which ones work and don't

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
