Answer:
139558.6
Step-by-step explanation:
Y=4x+7
So 4 is the rate of change because if you solve for y, x is the rate of change
Answer:
A = (5 x Z³) + (6 - X)
Step-by-step explanation:
given the information provided, this is the equation you're looking for
Jaqleen unloads a truck in x hours and Marco takes 2x hours.
Working together (x*2x) / (x+2x) = 5 hours
2x^2 / 3x = 5 Multiplying both sides by 3x equals 2x^2 -15x = 0
x = 7.5 hours
So Jaqleen takes 7.5 hours and Marco takes 15 hours
Double-Check (7.5 * 15) / (7.5 + 15) = 112.5 / 22.5 equals
5 hours Correct!!
