Answer:
y = 2w - 1 + aw
Step-by-step explanation:
Given
y - aw = 2w - 1 ( isolate y by adding aw to both sides )
y = aw - 1 + aw
15^x - 23.76
15 is how much each wash is
X is how many dogs she washes in a week
-23.76 is how much she paid for the shampoo
If you writ a graph start at (0,23.76)
X is the dogs she washes
Y the money she earned
Answer:
(a)
(b) There will be 1lb left after 14 hours
Step-by-step explanation:
Solving (a): The equation
Since the substance decomposes at a proportional rate, then it follows the following equation
Where
Initial Amount
rate
time
Amount at time t
Solving (b):
We have:
First, we calculate k using:
This gives:
Substitute:
Divide both sides by 4
Take natural logarithm of both sides
This gives:
Solve for k
So, we have:
To calculate the time when 1 lb will remain, we have:
So, the equation becomes
Divide both sides by 8
Take natural logarithm of both sides
Solve for t
--- approximated
Slope is a number that represents how much the y-value changes over a certain span of x-values. However, since y is a constant set to 3, the y-value never changes, meaning the slope is 0.
The slope will always be 0 for any equation that has the form:
You could also choose two random points and solve for the slope. Let's take (0,3) and (1,3).
You can verify these are actual points on the line since the y-value is 3.
Now, let's calculate for slope:
The slope is indeed 0 as shown from this.
