if the domain of a function that is reflected over the x axis is (3,4)(2,-1)(-1,2) what is the range? answers asap plz
The range of the reflected function consists of these reflected y-values. The range of the reflected function is (-4, -2, 1).
The range of a function reflected over the x-axis can be determined by considering the y-values of the original domain. In this case, the given domain points are (3,4), (2,-1), and (-1,2). The reflected points will have the same x-coordinates but opposite y-coordinates. Therefore, the reflected range will be the set of y-values obtained by changing the signs of the y-values in the original domain.
The original domain points have y-values of 4, -1, and 2. When reflected over the x-axis, these y-values become -4, 1, and -2, respectively.
Thus, the range of the reflected function consists of these reflected y-values. The range of the reflected function is (-4, -2, 1).

Answer:
Question 1). Option C.
Question 2) Option C.
Question 3) Option D.
Step-by-step explanation:
Question 1), A. 7 - (9x + 3) = -9x -4
7 - 9x - 3 = -9x - 4
-9x + 4 = -9x - 4
Left hand side(L.H.S.)≠ Right hand side(R.H.S.)
Therefore, it's not an identity
B). 6m - 7 = 7m + 5 -m
6m -7 = 6m + 5
Again L.H.S.≠R.H.S.
So, it's not an identity.
C). 10p + 6 - p = 12p - 3(p - 2)
9p + 6 = 12p - 3p + 6
9p + 6 = 9p + 6
L.H.S.=R.H.S.
Therefore, it's an identity.
D). 3y + 2 = 3y - 2
L.H.S. ≠ R.H.S.
Therefore, it's not an identity.
Question 2. Part A. 7v + 2 = 8v - 3
7v - 8v = -2 - 3
- v = - 5
v = 5
Part B. 3x - 5 = 3x + 8 - x
3x - 5 = 2x + 8
3x - 2x = 8 + 5
x = 13
Part C. 4y + 5 = 4y - 6
This equation has no solution.
Part D. 7z + 6 = -7z - 5
7z + 7z = -6 - 5
14z = -11
z = [tex]-\frac{11}{14}[/tex]
Question 3). 5 + 7x = 11 + 7x
This equation has same coefficient of variable x on both the sides of the equation.
Therefore, equation has no solution.

Lucas and Erick are factoring the polynomial
12x3 – 6x2 + 8x – 4. Lucas groups the polynomial (12x3 + 8x) + (–6x2 – 4) to factor. Erick groups the polynomial (12x3 – 6x2) + (8x – 4) to factor. Who correctly grouped the terms to factor? Explain.
Both students are correct because polynomials can be grouped in different ways to factor. Both ways result in a common binomial factor between the groups. Using the distributive property , this common binomial term can be factored out. Each grouping results in the same two binomial factors.
What is the simplified form of the following expression? (n5)(n2)
Final answer:
The simplified form of the expression (n⁵)(n²) is found by adding the exponents since the base is the same, resulting in n⁷.
Explanation:
The simplified form of the expression (n⁵)(n²) is achieved by applying the laws of exponents. Since both terms have a common base of n, when multiplying two exponentials with the same base, we simply add their exponents.
The addition of 5 and 2 (the exponents) provides n⁵⁺² which simplifies to n⁷.
Hence, the simplified form of (n⁵)(n²) is n⁷.

A train leaves New York for Boston, 200 miles away, at 4:00 P.M. and averages 75 mph. Another train leaves Boston for New York on an adjacent set of tracks at 5:00 P.M. and averages 40 mph. At what time will the trains meet? (Round to the nearest minute.)
The trains will meet at 6:40 P.M. after traveling at different speeds towards each other.
The trains will meet at 6:40 P.M.
To calculate the time when the trains will meet, we need to determine the time it takes for the second train to cover the distance that the first train has already covered.
The first train covers the 200-mile distance in 200 / 75 = 2.67 hours, which is 2 hours and 40 minutes.
The second train leaves at 5:00 P.M., so adding 2 hours and 40 minutes gives us 7:40 P.M. as the time the second train reaches the meeting point.
By then, the first train has been traveling for 3 hours and 40 minutes, making the meeting time 6:40 P.M.
A person is standing exactly 36 ft from a telephone pole. There is a 30° angle of elevation from the ground to the top of the pole. What is the height of the pole?
The height of the telephone pole is approximately 20.79 feet, calculated using tangent function with a 30° angle.
To find the height of the telephone pole, we can use trigonometry. We'll use the tangent function since we have the opposite side and the adjacent side of the right triangle formed by the person, the pole, and the ground.
Let [tex]\( h \)[/tex] be the height of the pole.
We have the tangent of the angle:
[tex]\[ \tan(30^\circ) = \frac{h}{36} \][/tex]
Now, we can solve for [tex]\( h \):[/tex]
[tex]\[ h = 36 \times \tan(30^\circ) \][/tex]
Let's calculate:
[tex]\[ h = 36 \times \tan(30^\circ) \]\[ h = 36 \times 0.5774 \] (rounded value of tan(30°))\[ h \approx 20.7864 \][/tex]
So, the height of the telephone pole is approximately 20.79 feet.

Benito is selling T-shirts for $8 each for his school fund-raiser. So far, he has sold 16 T-shirts. How many more does he need to sell to reach his goal of $200 in sales?
Three of these equations solve for the number of T-shirts, t, he still needs to sell to reach $200 in sales. Which equation does NOT?
a) t=9
b)8t+128=200
c)8(t+16)=200
d)8t+16=200
Answer:
Its D) 8t + 16 = 200
Answer: The correct option is (d) [tex]8t+16=200.[/tex]
Step-by-step explanation: Given that Benito is selling T-shirts for $8 each for his school fund-raiser and he has sold 16 T-shirts till now.
We are to find the number of T-shirts that he still need to sell to reach his goal of $200 in sales.
The number of T-shirts still he needs to sell is represented by t.
The, according to the given information, we have
[tex]8(t+16)=200\\\\\Rightarrow 8t+128=200\\\\\Rightarrow 8t=200-128\\\\\Rightarrow 8t=72\\\\\Rightarrow t=\dfrac{72}{8}\\\\\Rightarrow t=9.[/tex]
So, the number of T-shirts that he still needs to sell is 9.
Now, we can see from the above steps of solution for t that options (a), (b) and (c) gives the correct value of t, but from option (d), we get
[tex]8t+16=200\\\\\Rightarrow 8t=200-16\\\\\Rightarrow 8t=184\\\\\Rightarrow t=23\neq 9[/tex]
So, option (d) does NOT solve for the correct value of t.
Thus, (d) is the correct option.

Write log8 3 as a logarithm of base 5.
1) (log3)5/(log8)5
2) (log5)3/(log5)8
3) (log8)5/(log3)5
4) (log5)8/(log5)3 ...?
To write log8 3 as a logarithm of base 5, we can use the change of base formula: loga b = logc b / logc a. Applying this formula, we have log5 3 = log8 3 / log8 5. Therefore, the correct option is (log8)5/(log3)5.
Explanation:The expression log83 represents the logarithm of 3 with base 8. To write it as a logarithm with base 5, we can use the change of base formula:
logab = logcb / logca
Applying this formula, we have:
log53 = log83 / log85
Therefore, the correct option is (log8)5/(log3)5.
