Function rule: a = 20w + 115
Slope: 20
Initial value: 115
------------------------------------------
We start with $115 in the account. This is the initial value. Each week we add on $20.
So we add $20 for 1 week
We add 2*20 = $40 for 2 weeks
We add 3*20 = $60 for 3 weeks
etc etc
In general, we add 20*w dollars for w weeks onto 115 to get a = 20w+115
The slope is 20 because this is the rate of change, ie how fast the account grows. It grows 20 dollars per week.
Answer:
i cant see your pic
Step-by-step explanation:
The answer would be 5/55 because if you subtract 32 from 37 you would end up with 5 and because the denominator was the same you keep the denominator the same.
Answer:
<h2>
![{g}^{ - 1} (x) = \sqrt[5]{ - x - 3}](https://tex.z-dn.net/?f=%20%7Bg%7D%5E%7B%20-%201%7D%20%28x%29%20%3D%20%20%5Csqrt%5B5%5D%7B%20-%20x%20-%203%7D%20)
</h2>
Step-by-step explanation:
<h3>
</h3>
To find the inverse of g(x) equate g(x) to y
That's
<h3>
</h3>
<u>Next interchange the terms</u>
x becomes y and y becomes x
We have
<h3>
</h3>
<u>Next make y the subject</u>
Multiply both sides by - 1
That's
<h3>
</h3>
Send 3 to the right side of the equation
That's
<u>Find the 5th root of both sides</u>
That's
<h3>
![\sqrt[5]{ {y}^{5} } = \sqrt[5]{ - x - 3} \\ y = \sqrt[5]{ - x - 3}](https://tex.z-dn.net/?f=%20%5Csqrt%5B5%5D%7B%20%7By%7D%5E%7B5%7D%20%7D%20%20%3D%20%20%5Csqrt%5B5%5D%7B%20-%20x%20-%203%7D%20%20%5C%5C%20y%20%3D%20%20%20%5Csqrt%5B5%5D%7B%20-%20x%20-%203%7D%20)
</h3>
We have the final answer as
<h3>
