The remaining amount after 4 years is 1.25 kg
<h3>How to determine the remaining amount?</h3>
The half life of a function is represented as:
Where
Ao represents the initial amount
So, we have:
In 4 years, t = 4.
So, we have:
This gives
Evaluate the expression
A = 1.25
Hence, the remaining amount after 4 years is 1.25 kg

Answer:
y=-1/2x+1
Step-by-step explanation:
We can use the points to find the slope of the line.
Equation: y₂-y₁/x₂-x₁
2-4/-2-(-6)
2-4/-2+6
-2/4
-1/2 is the slope of the line
So the equation is y=-1/2x+b
We can substitute one of the x-coordinates and the matching y-coordinate into this equation:
2=-1/2*(-2)+b
2=1+b
1=b
b=1
Therefore, the equation is y=-1/2x+1
none are correct. the right answer is 4y=16x-8 is equivalent to y=4x-2
Answer: 6 inches.
Step-by-step explanation:
Answer:
y - 3 = -3 ( x - 7 )
Step-by-step explanation:
→ It is true for all values as you substitute in the x value and get the y as the output
