Y = –3x + 6 y = 9
What is the solution to the system of equations?

(–21, 9)
(9, –21)
(–1, 9)
(9, –1)

the answer is c

Step-by-step explanation:

because i just took the test

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 %

its very big question plz make it small
