(05.02) choose the equivalent system of linear equations that will produce the same solution as the one given below. (1 point) 4x ? 2y = 6 2x + y = 5 select one: a. ? 4x ? 2y = 10 ? 4y = 4 b. ? 4x ? 5y = ? 1 ? 7y = 5 c. 3x + 2y = 6 7x = 12 d. 4x + 2y = 10 8x = 16

Assume cd | ab are parallel. find m2. a) x= 50° (b) x = 70° c) x = 30° d) x = 60

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.)

This graph shows which inequality? a ≤ –3 a > –3 a ≥ –3 a < –3
