Answer:
468.74.
Step-by-step explanation:
We have been given that z varies directly as x and inversely as y. We can represent this information in an equation as:
First of all, we will find constant of variation using our given equation.
Upon substituting our given values in our equation, we will get:
Therefore, z is approximately 468.74.
Answer:
(-5, 0) and (0,4)
Step-by-step explanation:
Given equation: -4x + 5y = 20
Sub. in the values
When x = -5 and y = 0 (-5,0),
When x = 0 and y = 4 (0,4),
That's how I would do it, not sure if your school has another method. Hope this helps :)
Answer:
44%
Step-by-step explanation:
Solution:
Calculate percentage change
from V1 = 2000 to V2 = 1120
(V2−V1)|V1|×100
=(1120−2000)|2000|×100
= −8802000×100
= −0.44×100
= −44%change
= 44%decrease
