Solve this system for equations by graphing. First graph the equations, and then type the solution. y=3x+4
y=-3x-2

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

entering that problem on the tube might get you an answer

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
