Answer:
The values of y for each value of x are:
[tex]x = -3, y =2[/tex]
[tex]x = -2\: , y =-2[/tex]
[tex]x = -1\: , y =-4[/tex].
[tex]x = 0\: , y =-4[/tex]
[tex]x = 1\: , y = -2[/tex].
[tex]x = 2\: , y =2[/tex]
[tex]x = 3\: , y = 8[/tex]
Step-by-step explanation:
We have all the values of x, they are from -3 to 3 passing for 0.
Now, we know that y is a quadratic function (y=x²+x+4)
Therefore, we just need to put each value of x into the quadratic equation to find each y value.
When:
[tex]x = -3, y = (-3)^2+(-3)-4=2[/tex]
[tex]x = -3\: , y = 2[/tex]
We can do this for all values of x, so we will have:
[tex]x = -2\: , y = (-2)^2+(-2)-4=-2[/tex]
[tex]x = -1\: , y = (-1)^2+(-1)-4=-4[/tex].
[tex]x = 0\: , y = (0)^2+(0)-4=-4[/tex]
[tex]x = 1\: , y = (1)^2+(1)-4=-2[/tex].
[tex]x = 2\: , y = (2)^2+(2)-4=2[/tex]
[tex]x = 3\: , y = (3)^2+(3)-4=8[/tex]
I hope it helps you!

The measure of angle R is 3 degrees less than twice the measure of angle S. If the sum of the measures of the two angles is 72 degrees, find the measure of each angle.
Measures of the given angles:
∠S = 25° and ∠R = 47°
What is an angle?In geometry, an angle is formed when two rays are joined at their endpoints. These rays are called the sides or arms of the angle.
There are two main parts related to an angle - the arms and the vertex.
Given,
Measure of angle R is 3 degrees less than twice the measure of angle S
⇒ 2∠S - ∠R = 3°
⇒ ∠R = 2∠S - 3° ------(a)
Sum of R and S
⇒ ∠R + ∠S = 72°
Substituting ∠R in terms of ∠S in above equation from equation (a)
2∠S - 3° + ∠S = 72°
3∠S - 3° = 72°
3∠S = 72° + 3°
3∠S = 75°
∠S = 75°/3
∠S = 25°
Substituting value of ∠S in equation (a)
∠R = 2 × 25° - 3°
∠R = 50° - 3°
∠R = 47°
Hence, ∠S = 25° and ∠R = 47° are the measures of given angles.

Student’s Answer Key Ch.2 Grammar Advantage Eric Nelson & George Yule © 2019 Student’s Answer Key, Chapter 2, Sentence structure, Grammar Advantage
For most exercises, this key does not include even-numbered items.
■ Exercise 1 Read the passage. Based on what you already know, underline the verbs.
The Marshmallow Experiment
Imagine that you are seven years old. You are participating in an experiment. A researcher greets you and shows you into a small room. In the room there is a marshmallow. The marshmallow is for you, but here is the interesting part: The researcher tells you that he is going to leave you alone in the room for a while. You can eat the marshmallow right away, or you can wait until he gets back. If you wait until he gets back, you will get a second marshmallow.
What do you do? Do you eat the marshmallow right away?
An experiment like this, known informally as the marshmallow experiment, was conducted decades ago at Stanford University. It turned out that some children ate the marshmallow right away, while others were able to wait. In other words, some sought instant self-gratification, and some delayed it.
Years later, the researchers followed up on the participants. They found that the children who delayed self-gratification were in general more successful than those who ate the marshmallow right away. By a variety of measures, including SAT scores, they appeared to be more competent.
Common sense tells us that the ability to delay self-gratification is a mark of maturity. The marshmallow experiment provides evidence that it may also correlate with success in life.
Notes:
- Many of these verb phrases consist of an auxiliary verb and a main verb. So, for example, “are participating” and “do...eat” are considered verb phrases.
- “is going to leave”: If we consder “is going to” a kind of auxiliary verb, then this is a verb phrase, just like “will leave.”
- “known as...”: If you underlined “known,” that’s fine. It is a verb. It is a nonfinite verb, unlike the other underlined verbs and verb phrases. (See Chapter 4.)
■ Exercise 2 Underline the complete subjects in the sentences below, and double- underline the verbs that go with them. Identifying the subject means identifying the main word of the subject and the parts that modify it. (In the first sentence, the main word is in boldface.) When you underline the verb, include both auxiliary verbs and main verbs (as in the first sentence, with was...used).
In the 1960s and 70s, the term “generation gap” was often used to refer to the differences between young people in the U.S. and their parents’ generation. Many young people felt distant from their parents because of differences in ideas about politics, social issues, and popular culture. Since then, conflicts between generations have diminished in many ways. Child-rearing experts in the late 20th century encouraged parents to be like friends to their children. Thanks to technology, young people and their parents are able to contact each other easily at any time. On any college campus, the students you see texting or talking on cell phones are often communicating with Mom or Dad. Fifty years ago, closeness of this kind was less

Please helppp me with this math problem
Answer:
length: 38 feet
width: 10 feet
area: 380 ft²
Step-by-step explanation:
The scale between the drawing and the actual studio is 2 in : 5 ft. If we divide both sides by 2, we find that the scale is 1 in : 2.5 feet.
For the first number, 15.2 inches, if we multiply it by 2.5 and change the label to "feet", we can find the real length.
15.2 * 2.5 = 38.
The length is 38 feet.
For the width, do the same thing.
4 * 2.5 = 10
The width is 10 feet.
Area is length times width. So if we plug in the numbers we just found:
38 * 10 = 380.
The area is 380 ft²

Solve this equation:
2(x + 5) = 3x + 1
Answer:
x = 9
Step-by-step explanation:
Distribute
2x+2*5=3x+1
2x+10=3x+1
Subtract 3x from both sides
-x+10=1
Subtract 10 from both sides
-x=-9
Multiply both sides by -1
x=9
Answer: x=9
Step-by-step explanation: 2(x + 5) = 3x + 1
2(x+5)
2x+2(5)
2x+10-10= 3x + 1-10
2x-3x=3x-9-3x
-x/-1=-9/-1

Which function has a greater rate of change? Function A: x 1.5 2.5 3.5 4.5 5.5 y 5 0 –5 –10 –15 Function B: y = –4.5x + 15 Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function A has a greater rate of change. Function A has a rate of change of 5 and Function B has a rate of change of 4.5, so Function B has a greater rate of change. Function A has a rate of change of –5 and Function B has a rate of change of –4.5, so Function B has a greater rate of
Answer:
Function A has a rate of change of -5 and Function B has a rate of change of -4.5, so Function B has a greater rate of
Step-by-step explanation:
Function A:
[tex]\begin{array}{cccccc}x & {1.5} & {2.5} & {3.5} & {4.5} & {5.5} \ \\ y & {5} & {0} & {-5} & {-10} & {-15} \ \end{array}[/tex]
Function B:
[tex]y = -4.5x + 15[/tex]
Required
Which has a greater rate of change
The rate of change of function A is calculated as thus:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
Where:
[tex](x_1,y_1) = (1.5,5)[/tex]
[tex](x_2,y_2) = (2.5,0)[/tex]
So, we have:
[tex]m = \frac{0-5}{2.5 - 1.5}[/tex]
[tex]m = \frac{-5}{1}[/tex]
[tex]m = -5[/tex]
For function B
The general function is:
[tex]y = mx + b[/tex]
Where
m is the rate of change
By comparing [tex]y = mx + b[/tex] to [tex]y = -4.5x + 15[/tex]
[tex]m = -4.5[/tex]
So, we have that:
Function A has a rate of -5; function B has a rate of -4.5.
By comparison: -4.5 is greater than 5
Hence, function B has a greater rate.
