What is simple interset?</h3>
Simple Interest is an easy method of calculating the interest for a loan/principal amount.
Given
Frank invests $1,000 in simple interest investment account that pays 8% a year.
After a number of years, he withdraws his balance of $2,200.
The number of years was his money inversted is;
![\rm I= P\times r \times t](https://tex.z-dn.net/?f=%5Crm%20I%3D%20P%5Ctimes%20r%20%5Ctimes%20t)
Where p is the principal amount, r is the rate of interest, I is the amount and t is the time.
Substitute all the values in the formula;
![\rm I= P\times r \times t\\\\2200-1000= 1000 \times .08 \times t\\\\1200 = 80t\\\\t = \dfrac{1200}{80}\\\\t=15](https://tex.z-dn.net/?f=%5Crm%20I%3D%20P%5Ctimes%20r%20%5Ctimes%20t%5C%5C%5C%5C2200-1000%3D%201000%20%5Ctimes%20.08%20%5Ctimes%20t%5C%5C%5C%5C1200%20%3D%2080t%5C%5C%5C%5Ct%20%3D%20%5Cdfrac%7B1200%7D%7B80%7D%5C%5C%5C%5Ct%3D15)
Hence, in the 15 years was his money invested.

Step-by-step explanation:
In a quadratic function, the solutions are always on the x-axis, which means that it can be another word for x-intercept. Also, a zero and a root are the same thing, and they are both x-intercepts. Hope this helps!
The direct variation equation is y = kx.
In this case, the equation is y = 1.8x.
Substitute the given points into the equation. If the x and y coordinate of a point satisfies the equation and both sides are equal, then that point is your answer.
