y ≤ 0
ExplanationRemember that the range is all the possible y-values that the relation can take. We can see in the picture that the repletion is always bellow of the positive y-axis, so the relation can take only negative y-values or zero. In other words, the range of the relation is all the y-values greater or equal than zero, which we represent with the inequality: y ≤ 0. The domain, on the other hand, is all the real numbers; since x can take any value.

y ≤ 0 is the correct answer

What is the length of line RS? Use the law of sines to find the answer.Round to the nearest tenth.
Answers
Let x = length of line segment RS.
Let Q = ∠RQS.
Let S = ∠RSQ
According to the Law of Sines,
[tex] \frac{sinS}{2.4} = \frac{sin80^{o}}{3.1} \\\\sinS = (\frac{2.4}{3.1}) sin 80^{o}= 0.7624 \\\\ S = sin^{-1}0.7624 = 49.68^{o}[/tex]
Because the sum of angles in a triangle is 180°, therefore
∠Q = 180 -(80 + 49.68) = 50.32°
Apply the Law of Sines again to obtain
[tex] \frac{x}{sinQ} = \frac{3.1}{sin80^{o}} \\\\ x = ( \frac{sin50.32^{o}}{sin80^{o}})3.1 = 2.423[/tex]

Answers
x+3y=-5
So, 6x-3y=33
x+3y=-5
Using elimination, 7x=28 or x=4.
Answer with Step-by-step explanation:
We have to determine the value of x on solving the system of linear equations:
2x-y = 11
x+3y = -5
2x-y=11
Adding y on both sides and subtracting by 11 on both sides, we get
y=2x-11
Putting value of y in x+3y = -5
x+3(2x-11) = -5
x+6x-33 = -5
7x -33 = -5
adding 33 on both sides, we get
7x= 28
Dividing by 7 on both sides, we get
x=4
Hence, Correct option is:

What is the vertex of y=6x^2-24x+30
Answers
(x - h)² = 4a(y - k)
(x - h)² = -4a(y - k)
(y - k)² = 4a(x - h)
(y - k)² = 4a(x - h)
You will notice that the equation contains an x². So, our choices will be narrowed down to:
(x - h)² = 4a(y - k)
(x - h)² = -4a(y - k)
where, the vertex has the coordinates (h.k)
y = 6x² - 24x + 30
Divide both sides by 6,
y/6 = x² - 4x + 5
y/6 - 5 = x² - 4x
Completing the squares, add (-4/2)² = 4 to both sides,
y/6 - 5 + 4 = x² - 4x + 4
y/6 - 1 = (x - 2)²
1/6(y - 6) = (x - 2)²
Thus, h=2 and k=6. The vertex is at point (2,6).
The vertex of the quadratic equation y = 6x^2 - 24 + 30 is (2, -6).
Explanation:The given equation is y = 6x^2 - 24x + 30.
To find the vertex of this quadratic equation, we can use the formula x = -b/2a.
In this equation, a = 6 and b = -24. Plugging these values into the formula, we get x = -(-24)/(2*6) = 24/12 = 2.
Now, substitute this value of x into the equation to find the corresponding y-coordinate of the vertex.
Substituting x = 2, we get y = 6(2)^2 - 24(2) + 30 = 12 - 48 + 30 = -6.
Therefore, the vertex of the given quadratic equation is (2, -6).

30 packages a minute are unloaded from a truck that has 2700 packages. How long would it take to unload the truck?
Answers
Please vote my answer brainliest. thanks!
It would take 90 minutes to unload a truck containing 2700 packages at a rate of 30 packages per minute.
Explanation:This problem involves performing a simple division operation. Given that 30 packages are unloaded from a truck each minute and there are a total of 2700 packages on the truck, we find the time it would take to unload the truck by dividing the total number of packages by the number of packages that can be unloaded each minute.
Solution:
We solve the problem as follows:
First, state the number of packages in the truck, which is 2700 packages. Next, note the rate at which packages are being unloaded per minute, which is 30 packages a minute. Then, we simply divide the total number of packages by the number of packages that can be unloaded per minute. This gives us the total time required to unload the entire truck, which is 2700⁄30 = 90 minutes.Therefore, it would take 90 minutes to unload the entire truck.

A circle is centered on point B, Points A, C and D lie on its circumference. if ABC measures 46 degrees, what does ADC measures?
Answers
---------------------------------------
---------------------------------------
Explanation:
Using the inscribed angle theorem we can connect the central angle ABC and the inscribed angle ADC. The reason why is because they both cut off the minor arc AC
Angle ABC is given to be 46 degrees, the formula we use is shown below
central angle = 2*(inscribed angle)
angle ABC = 2*(angle ADC)
46 = 2*(angle ADC)
46/2 = 2*(angle ADC)/2 ... divide both sides by 2
23 = angle ADC
angle ADC = 23 degrees
If ABC measures 46 degrees, then the central angle ADC measures 23 degrees.

write a system of linear equations with -3,9 as its solution
Answers
Solution of the equation is given to us, hence,
x = -3 and x = 9
x + 3 = 0 and x - 9 = 0
Multiplying,
(x + 3)(x - 9) = x² - 9x + 3x - 27 = x² - 6x - 27
Hence, the linear equation with solution -3 and 9 is x² - 6x - 27.
Final answer:
To create a system of linear equations with the solution (-3, 9), we need to construct two equations that intersect at this point, for example, y = -3x + 18 and y = 2x + 15.
Explanation:
To write a system of linear equations with the solution (-3, 9), we can create two separate equations that intersect at this point. Using the equation provided, y = 9 + 3x, we can see that the point (-3, 9) satisfies this equation since plugging in x = -3 gives us y = 9 + 3(-3) = 9 - 9 = 0, which is incorrect. We must correct the mistake and ensure that the solution (-3, 9) satisfies both equations in our system.
A correct form of the first equation would be y = -3x + 9 (not y = 9 + 3x as provided), since plugging x = -3 yields y = -3(-3) + 9 = 9 + 9 = 18, which is also incorrect. Therefore, we need to be careful in constructing our equations.
Let's construct two new equations correctly:
First, we start with the equation y = -3x + 18, which does satisfy the condition when x = -3 and y = 9. Next, we can create a different equation with the same solution. For instance, if we want another equation, we might use the slope-intercept form, y = mx + b. We can choose a different slope (m), for example, m = 2, and find b such that when x = -3, y = 9:
y = mx + b
9 = 2(-3) + b
9 = -6 + b
b = 15
So, the second equation is y = 2x + 15. The system of linear equations with the solution (-3, 9) is:
1. y = -3x + 18
2. y = 2x + 15
