Answer:
x=0
Step-by-step explanation:
1. 0=33.2x
2. 33.2x=0
One way to solve this is to revert to integers.
Do this by moving the decimal in 1.3 to the right 6 places (indicated by the positive power value) and then 6.8 move the decimal to the right 5 places (same reason)
Now you have 1,300,000 & 680000. Subtract to get 620,000.
Now convert your product to scientific notation again by moving your decimal to the left until you are left with 6.2 x ? The question mark will be 10 to the number of places you moved the decimal. 10^5
We have 6.2 x 10^5.
It is import to note that when the decimal must be moved to the right for values less than one, the power will be negative.
Answer: x=2 and y=4/3
Step-by-step explanation:
To solve by substitution method, you want to solve for one variable, and plug it into the other equation.
Let's solve for y in 2x+3y=8.
[subtract both sides by 2x]
[divide both sides by 3]
Now that we have y, we can plug it into the second equation.
[plug in y]
[multiply 3 and y to cancel out the 3]
[distribute -1 to 8-2x]
[combine like terms]
[add both sides by 8]
[divide both sides by 11]
Since we know the value of x, we can substitute it back into any of the 2 equations to find y.
[plug in x=2]
[multiply 2 and 2]
[subtract both sides by 4]
[divide both sides by 3]
Our final answer is x=2 and y=4/3.
Hello.
A decay function has a distinctive comportment:
<em>"If a < b, therefore f(a) > f(b)"</em>
So, the function must assume smaller values as x grows.
This is accomplished when 0 < b < 1
