<h3>What are Pronouns?</h3>

When your reader or listener already understands the nouns you're referring to, you can replace them with pronouns. As an illustration, you may say, "I have a dog. He is white and brown. You just mentioned your dog in the first phrase, so there's no need to explicitly state that you're describing him in the second. However, saying "brown and white" after "I have a dog" is grammatically incorrect; instead, you need the pronoun "he's" to make the phrase "brown and white" into a complete sentence. A pronoun's functions go well beyond simply converting phrases into sentences. They set the scene, clarify the meaning of your sentences, and influence how we view people and objects.

In , there were immigrants admitted to a country. In 1960, the number was . a. Assuming that the change in immigration is lin

Arisa [49]

Answer:

The answer is below

Step-by-step explanation:

The complete question is:

In 1960, there were 237,794 immigrants admitted to a country. In 2001, the number was 1,150,729.

a. Assuming that the change in immigration is linear, write an equation expressing the number of immigrants, y, in terms of t, the number of years after 1900.

b. Use your result in part a to predict the number of immigrants admitted to the country in 2013.

c. Considering the value of the y-intercept in your answer to part a, discuss the validity of using this equation to model the number of immigrants throughout the entire 20th century.

Answer:

a) From the question, we can get two ordered pairs which are $(t_1,y_1)=(60,237794)\ and\ (t_2,y_2)=(101,1150729)$

Using the equation of a line given two points:

$y-y_1=\frac{y_2-y_1}{t_2-t_1}(t-t_1)\\ \\y-237794=\frac{1150729-237794}{101-60}( t-60)\\\\y-237797=22266.71(t-60)\\\\y=22266.71t-1098205.44$

b) In 2013, t = 2013 - 1900 = 113.

Hence:

$y=22266.71t-1098205.44\\\\y=22266.71(113)-1098205.44\\\\y=1417932.488\\\\y=1417933$

$y=22266.71t-1098205.44\\\\the\ y\ intercept\ is\ at\ t=0,hence:\\\\y=22266.71(0)-1098205.44\\\\y=-1098205.44$

Since the y intercept is negative, that is in 1900 the number of immigrants was -1098206 which can not be possible. Hence this equation is not valid and the growth may or may not be linear.

Phil has 3 times as Many rocks as Peter together they have 48 how many more rocks does Phil have than Peter

Lena [83]

Phil will have 36 rocks, and since Phil has 3x more than Peter, you take 36/3 which equals 12, 12+36=48. then to find the difference you take 36-12 which equals 24

Solve the system using substitution and describe your steps. <br> x=y-3 <br> 2x+y=12

Misha Larkins [42]

X = y - 3 (equation 1)
2x + y = 12 (equation 2)

Substitute equation 1 into equation 2, replacing every x value with equation 1

2(y - 3) + y = 12

Now, distribute the 2 inside the brackets and simplify.
2y - 6 + y = 12
3y = 18
y = 6 (divided both sides by 3)

Substitute y back into equation 1 to find x.
x = 6 - 3
x = 3

Verify that these are correct by substituting them into equation 2.
2(3) + 6 = 6 + 6 = 12

Therefore, x = 3 and y = 6
