Select the correct answer from each drop-down menu. Which system of linear equations makes the sentence true? (-2x + y = 7, 3y = 6x + 4),(-2x = -11 - y, 2y = 4x + 3),(2x + y = 4, 5y = 10x + 4),(2x + y = -7, -6y = 12x + 42)is a system of linear equations representing intersecting lines.

(-2x + y = 5, 5y = 7x + 4),(2x = -1 - y, 2y = 6x + 5),(-4x + 2y = -9, 2y = 5x + 3),(2x + 3y = 21, -6y = 4x + 1)is a system of linear equations representing parallel lines.

(-2x + y = 3, 5y = 10x - 15),(-2x + 4y = 9, 8y = 4x + 18),(-x + 2y = 4, 6y = 3x + 11),(-7x + 3y = 1, -12y = 28x - 4)is a system of linear equations representing coincidental lines.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

27

step-by-step explanation:

46

step-by-step explanation:

given

height = 168 cm

formula

height =2.47*f+54.13

solution

168 = 2.47f + 54.13             subtract 54.13 from both sides

168 - 54.13   = 2.47f             combine

113.87 = 2.47f                     divide by 2.47

113.87 / 2.47 = f                   combine

46.1 = f  

answer: 46 cm
