Which systems of linear equations have no solution? x + y + z = 1,100
x-2y - Z=-500
2x + 3y + 2z = 2,600

x + y + z = 1,500
X-y-z= -500
2x + y + z = 2,000

x + y + z = 1,400
x-2y - z= -500
2x + 2y + 2z = 2,700

x + y + z = 1,400
-0.5x – 0.5y - 0.5z = -900
2x + 3y + 2z = 3,000

x + y + z = 1,900
X- y - 2z = -2,000
2x + 2y + z = 1,100

x + y + z = 2,400
2x - 2y + 2z = 700
x + 3y + z = 2,400
​

Which point is on the line y=-2+3? (-2,-1) (3,3) (3,-3) (-3,-9)

According to modern science, earth is about 4.5 billion years old and written human history extends back about 10,000 years. suppose the entire history of earth is represented with a 10-meter-long timeline, with the birth of earth on one end and today at the other end.

Use the frequency distribution, which shows the number of american voters (in millions) according to age, to find the probability that a voter chosen at random is in the 18 to 20 years old age range. ages frequency 18 to 20 5.9 21 to 24 7.7 25 to 34 20.4 35 to 44 25.1 45 to 64 54.4 65 and over 27.7 the probability that a voter chosen at random is in the 18 to 20 years old age range is nothing. (round to three decimal places as needed.)
