Answer:
y = -20
Step-by-step explanation:
Given that y varies directly with x it means changing x will also cause change in y
Mathematically it can be written as:
y∝x
Removing the proportionality symbol
y = kx
Given y=25 when x=5 Putting the values

Now

We have to find the value of y when x = -4
Putting x=-4

Hence,,
y = -20
The answer is: y= –1/3x–5
Answer:
x=12√2
y=45°
Step-by-step explanation:
as we know diagonal of a square
=a√2
=12√2
and
y=45°
Answer: 16
Step-by-step explanation: 80x20=1600
Put the decimal place where it belongs
80% of 20=16
