Manda swims 40 meters per minute. She uses the inequality below to calculate how many minutes, m, it takes her to swim at least 1,500 meters. 40m≥1,500
Which set of numbers makes the inequality true?

A. {24,25,37.5}
B. {25,28.5,37}
C. {37,39,40.5}
D. {37.5,42,43.5}

A

Step-by-step explanation:

i dont know sorry

step-by-step explanation:

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)
