You are a young person who lives in Judaea during the time of Jesus' ministry. You have attended his Sermon on the Mount. Write a letter to your grandparents telling them about it.

The estimated resident populations (in percent) of young people (age 14 and under) and seniors (age 65 and over) in the United States for the years 2015-2050 are modeled by the following linear functions.

$$\begin{array}{ll} y_1=-0.04 x+19.3 & \text { Young people } \\ y_2=0.17 x+16.4 & \text { Seniors } \end{array}$$

In each case, x represents the number of years since 2015. (a) Evaluate the system to determine the year when these population percents will be equal.

(b) Determine the percent, to the nearest tenth, of the U.S. resident population that will be young people or seniors in the year found in the previous part. Answer may vary due to rounding.

$(c)$ Using a calculator plot the system to support the algebraic solution.

(d) Determine which population is increasing.

Write the converse of the true conditional statement below. Then determine whether the converse is true or false. If you are less than 18 years old, then you are too young to vote in the United States.

(a) According to Lady Bracknell, how should a young girl learn she is engaged? (b) Infer: What do Lady Bracknell's remarks suggest about Victorian attitudes toward marriage and family?

Christ called himself a lamb because, like the Passover lamb slain to save the people of Israel, he sacrificed himself for the people. What might this imply about the fate of the young speaker in this poem?

A fishery stocks a pond with 1000 young trout. The number of trout $t$ years later is given by $P=1000e^{-0.5t}$.How many trout are left after six months? After 1 year?

In many instances, it is the adult members of the prey who are chiefly attacked by the predators, while the young members are better protected, either by their smaller size, or by their living in a different station. Let $x_1$ be the number of adult prey, $x_2$ the number of young prey, and y the number of predators. Then,

$$\begin{array}{l} {\dot{x}_{1}=-a_{1} x_{1}+a_{2} x_{2}-b x_{1} y} \\ {\dot{x}_{2}=n x_{1}-\left(a_{1}+a_{2}\right) x_{2}} \\ {\dot{y}=-c y+d x_{1} y} \end{array}$$

where $a_2x_2$ represents the number of young (per unit time) growing into adults, and n represents the birth rate proportional to the number of adults. Find all equilibrium solutions of this system.

Look again at the cluster diagram you made in your NOTEBOOK. What inferences can you make about young Larry Delaney's personality, on the basis of details about him in the story?

Eliot was in the avant-garde as a young poet, but he considered himself a traditionalist as he got older. What are the innovative aspects of this poem? Look for evidence of the traditionalism that would get stronger as Eliot aged.

Writing to Inform It is 1890 and you are a young immigrant who has recently arrived in America. Write a letter home to your parents describing your journey and your impressions of life in America.

Solve each problem using a system, of equations. The estimated resident populations (in percent) of young people (age 14 and under) and seniors (age 65 and over) in the United States for the years 2015-2050 are modeled by the following linear functions.

$$\begin{aligned} &y_{1}=-0.04 x+19.3 \quad \text { Young people }\\ &y_{2}=0.17 x+16.4 \quad \text { Seniors } \end{aligned}$$

In each case, x represents the number of years since 2015. (a) Solve the system to find! the year when these population percents will be equal. (b) What percent, to the nearest tenth, of the U.S. resident population will be young people or seniors in the year found in part (a)? Answer may vary due to rounding. (c) Use a calculator graph of the system to support the algebraic solution. (d) Which population is increasing?

Add commas where necessary. Delete commas used incorrectly using the delete symbol. Holding the puppy inside her coat Virginia waited to surprise her young cousins.

A fishery stocks a pond with $1000$ young trout. The number of trout $t$ years later is given by $P(t)=1000 e^{-0.5 t}$. Find $P(3)$ and interpret it in terms of trout.

Analyze how you would teach young children about poison safety. What safety rules would you share? How would you get children to remember and understand them?
