Hurry will mark brainliest!! 3. Solve the system of the equations: {v =*2-2x = 4
x + y = 2
a. (2,0),(-3,5)
b. (-2,3), (4,-1)
C. (-2,-4), (3,1)
d. (-2,4),(3,-1)

answer: i think the answer is etheir c or d but i don't know which one but have a good day!

step-by-step explanation:

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

a) one student is chosen from classroom a, then a student is chosen from classroom b.  

step-by-step explanation:

independent events are ones in which the probability of one event does not affect the probability of the second event.

one student is chosen from classroom a; this does not affect the chances of choosing a student from classroom b.   this makes these independent events.

when one card is chosen from a standard deck and then set aside before a second card is chosen, the probability of the second card being chosen changes.   this makes them dependent events.

when one student is chosen from classroom a and then a second student is chosen from classroom a, the probability of choosing the second student changes.   this makes them dependent events.

when a letter is chosen from the alphabet and then a second letter is chosen, the probability of choosing the second letter changes.   this makes them dependent events.

b

step-by-step explanation:

it have 5 sides and 5 identicle angle.the rest does not have the same property as b.
