Answer:
1 - 4y
Step-by-step explanation:
0.5 - Y - 5 -0.5x = y - 5
0.5 +5 -5 -0.5x = 2y
0.5 -2y = 0.5x
x = 0.5 - 2y /0.5
= 1 - 4y
Answer:
Step-by-step explanation:
y= -3x+1
you use inverse operations, and since you want the y alone, you subtract 3x on both sides, giving you y= -3x+1
<span>The answer is 9,990 years. Using the exponential decay question, we can figure out how long it will take Plutonium-240 to decay from 27 grams to 9 grams. Setting the equation up looks like this, 9 = 27 e^ (-0.00011 t). From this you get, 0.333333 = e ^(-0.00011 t). Next, you simplify by dividing both sides by the natural log, -1.0986 = -0.00011 t. Finally, you solve by dividing both sides by -0.00011, giving 9,987 years for t, rounded up to 9,990 years.</span>
If you are just estimating then you should round 15.12 to 15 and multiply that by 8- then take that outcome and divide it by 24 (how many hours are in a day) then you get your answer
