- Show all work to verify if the given point is a solution to the system of equations.arrow_forwardSample Stud 3) y=-3x - 9 -2x - 2y = 10 Solving Systems of Equations using Substitutionarrow_forwardThe owl population in a year n can be divided into juveniles, subadults andadults. Adults produce, on average, 0.4 juveniles each year. Approximately53% of juveniles survive to be subadults the next year, while 73% of subadultssurvive to become adults. Approximately 89% of the adult population survivesfrom one year to the next.1. Write down the equations for juveniles, subadults and adults in the year n+1 as functions of the juvenile,subadult and adult populations at year n. Explain all terms.2. Carefully explaining your notation and the terms, write down a matrix equation of the form pn+1 = Apn. 3. If there are 21 juveniles, 17 subadults and 53 adults this year, how many of each would we expect nextyear? 4. What is the equation that would describe the population in 5 years? (Do not calculate it!)arrow_forward
- 1) Find the general solution of the linear system. x = -5 6-4 X.arrow_forwardShow all work to verify if the given point is a solution to the system of equations. (3y² + 3x² = 6 4y² — 16x² + 12 = 0 Point: (-1,-1)arrow_forward1. Explain the difference between an equation and a system of equations. Discuss the solution(s) in your explanation.arrow_forward
- 5. Find solution of the system of linear equations. Write clean, and clear. Show steps of calculations. 2x1 – x2 + 2x3 = 4 - -x1 + 3x2 – x3 = 5 | 3x1 + x2+33 = -6arrow_forwardIs it possible for a system of equations which involves two or more variables to have no solution? Does this system of equations have a solution? 2x + 3y = 6, 2x + 3y = 12? How can one deduce whether a system of equations has a solution? Explain.arrow_forward
