- Is (20,52) a solution to the system of equations below? Show your work. y = 0.75x + 37 y = 1.5x + 22arrow_forwardCan you please indicate the step by step solution? Thank you.arrow_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

Also shown is the percentage of households in which a person of faith is married to someone with no religion.The formulaI =1/4x + 26 models the percentage of U.S. households with an interfaithmarriage, I, x years after 1988. The formula N =1/4x + 6 models the percentage of U.S. households in which a person of faith is married to someone with no religion, N, x years after 1988.In which years will more than 34% of households have an interfaith marriage and more than 15% have a faith/no religion marriage?arrow_forwardThe bar graph shows the percentage of households with an interfaithmarriage in 1988 and 2012.
