Answer: (2.5,0)
So you substitute (replace) the y value with what y equals
In this case, y=2x-5
So you replace that with the y in the equation. Therefore creating a method called the distributive property!
Where you distribute (multiply) the number outside of the parentheses to all the numbers inside the parentheses. Leaving you with the next method! Which is combine like terms. Take all the numbers with the x values and add them and do the same thing to the regular whole numbers without values. Leaving you with an x valued number on one side of the equal sign and a regular whole number on the other side. Since you can’t combine these two numbers you divide them to each other.
Leaving you with your solution
In this case your solution is (2.5,0)!!

Answer:
Step-by-step explanation:
The standard compound interest formula is given by:
Where A is the amount afterwards, P is the principal, r is the rate, n is the times compounded per year, and t is the number of years.
Since we are compounding annually, n=1. Therefore:
Lester wants to invest $10,000. So, P=10,000.
He wants to earn $1000 interest. Therefore, our final amount should be 11000. So, A=11000.
And our timeframe is 3.3 years. So, t=3.3. Substituting these values, we get:
Let’s solve for our rate r.
Divide both sides by 10000:
We can raise both sides to 1/3.3. So:
The right side will cancel:
So:
Use a calculator:
So, the annual rate of interest needs to be about 0.03 or 3% in order for Lester to earn his interest.
