- 3 = xy + z
xy + z = - 3
subtract z from both sides:
xy +z - z = -3 - z
yx = - 3 - z
Divide both sides by y :
yx / y = - 3 - z / y
x = -3-z / y
y ≠ 0
hope this helps!
Answer:
Zero.
Step-by-step explanation:
The minimum value is where the function touches the x axis , at y = 0.
Step-by-step explanation:
open the bracket
6={(1/5×4y) + 1/5×10}
6=4/5y+2
6-2=4/5y
4=4/5y
divide both sides by 4/5
y=1/5
Answer:
300 cm^2
Step-by-step explanation:
The volume of the rectangular prism is calculated by multplying lenght to the widht to the height
