Answer: x^2−xy+1
Step-by-step explanation:
simplify:
5+x^2−xy−4
5+x^2+−xy+−4
Combine Like Terms:
5+x^2+−xy+−4
(x^2)+(−xy)+(5+−4)
x^2+−xy+1
Answer:
If you want me to give you a WRONG answer, then -1.
For this case we have a function of the form:
![y = A * (b) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%20A%20%2A%20%28b%29%20%5E%20x%20%20)
Where,
A: initial value of an autographed baseball
b: growth rate
x: number of years
Substituting values we have:
![y = 300 * (1.05) ^ x](https://tex.z-dn.net/?f=%20y%20%3D%20300%20%2A%20%281.05%29%20%5E%20x%20%20)
For the moment when the value is at least 650 $ we have the following inequality:
![300 * (1.05) ^ x \geq 650](https://tex.z-dn.net/?f=%20300%20%2A%20%281.05%29%20%5E%20x%20%5Cgeq%20650%20%20%20)
Answer:
a one-variable inequality that could be used to solve for the number of years, x, it would take for the baseball to be worth at least $650 is:
![300 * (1.05) ^ x \geq 650](https://tex.z-dn.net/?f=%20300%20%2A%20%281.05%29%20%5E%20x%20%5Cgeq%20650%20%20)
A=p(1+i/m)^mn
A=26,000÷(1+0.06÷2)^(2×7)
A=17,189.06
Oh you have to make a list of things with a price make sure it adds up to that number
