The sum of the expression (–x² + x) and (x² – 3x – 1) will be –2x – 1. Then the correct option is D.
<h3>What is Algebra?</h3>
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
The expression can be written as
(–x² + x) and (x² – 3x – 1)
Then the sum of the expression (–x² + x) and (x² – 3x – 1) will be
(–x² + x) + (x² – 3x – 1) = –2x – 1
Then the correct option is D.

Answer:
xy=2
Step-by-step explanation
2x + 3y =12
First divide 2 on both sides of the equation, than divide 3 on both sides of the equation.

NOW, whats the question?
I think more information is needed please
Answer:
1.) The 1ˢᵗ three term is (-32), (-7) and 18
2.) The 1ˢᵗ three term is 127, 106 and 85
Step-by-step explanation:
<h2>1.)</h2>
Here,
First Term = a₁ = - 32
Common Difference = (d) = 25
Now, For 1ˢᵗ three term,
<u>n = 1</u>
a₁ = - 32
<u>n = 2</u>
<em>aₙ = a + (n - 1)d</em>
a₂ = (-32) + (2 - 1) × 25
a₂ = (-32) + 1 × 25
a₂ = (-32) + 25
a₂ = -7
<u>n = 3</u>
<em>aₙ = a + (n - 1)d</em>
a₃ = (-32) + (3 - 1) × 25
a₃ = (-32) + 2 × 25
a₃ = (-32) + 50
a₃ = 18
Thus, The 1ˢᵗ three term is (-32), (-7) and 18
<h2>2.)</h2>
Here,
First Term = a₁ = 127
Common Difference = (d) = -21
Now, For 1ˢᵗ three term,
<em>n = 1</em>
a₁ = 127
<u>n = 2</u>
<em>aₙ = a + (n - 1)d</em>
a₂ = 127 + (2 - 1) × (-21)
a₂ = 127 + 1 × (-21)
a₂ = 127 - 21
a₂ = 106
<u>n = 3</u>
<em>aₙ = a + (n - 1)d</em>
a₃ = 127 + (3 - 1) × (-21)
a₃ = 127 + 2 × (-21)
a₃ = 127 - 42
a₃ = 85
Thus, The 1ˢᵗ three term is 127, 106 and 85

Answer:
1. 80° F
2. 12:00 noon
3. 85°F
4. After 2 P.M. in the afternoon.
5. At 2 A,M
Step-by-step explanation:
In Peach Tree City the temperature (T) in Fahrenheit over a 20-hour period is shown in the given graph.
1. From the graph, it is clear that T(10) = 80° F (Approximate)
2. IF t = 0 corresponds to 12:00 midnight, then the meaning of T(12) means the temperature at the 12:00 noon.
3. The highest temperature during the 12 hour period is 85°F (Approximate).
4. The temperature starts to decrease after 2 P.M. in the afternoon.
5. The temperature gets over 70°F after 6 A.M. So, Taylor Swift should start his 4 hours return trip at 2 A.M. (Answer)
