Name two numbers that add to -6 and multiply to 5

An object is accelerating at a constant rate. its velocity in feet per second as a function of time in seconds can be modeled by the linear function v(t) = 2.5t. what does the dependent variable represent for this function? a) acceleration b) distance c) slope d) velocity

Me because i don't understand how to do it.: )

What is the solution to the system of equations? 10x+3y=8 -9x-y=-20 (11, 1) (1, 11) (–1, 11) (11, –1)'
