Answer:
y = - 4x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and c the y- intercept )
Here m = - 4, thus
y = - 4x + b ← is the partial equation
To find b substitute (- 2, 5) into the partial equation
5 = 8 + b ⇒ b = 5 - 8 = - 3
y = - 4x - 3 ← equation of line

Answer:
450
Step-by-step explanation:
90 ice cubes time 5 trays equals a total of 450 ice cubes
Answer:
60 hours
Step-by-step explanation:
Let X be the total capacity.
Inlet speed: X/15
Outlet speed: X/20
Combined:
X/15 - X/20 = X/60
X/60 = X/time
Time = 60 hours
