Answer:
y = -3/4x -2
Step-by-step explanation:
Slope intercept is y = mx+b where m is the slope and b is the y intercept
4y = -3x-8
Divide each side by 4
4y/4 = -3x/4 -8/4
y = -3/4x -2
Multiply 120 by 0.40 to get 40%:
120 x 0.40 = 48
So 48 is 40% of 120
21:30 and 35: and 50 this is because 7 times 3 is 21, 10 times 3 is 30, and 7 times 5 is 35, and lastly 10 times 5 is 50
C) They solve the same number of problems per minute
172.5 Divided by 2
115 divided by 2
= 57.5
