Answer:
They are parallel
Step-by-step explanation:
Ignore the +3 and the +6 for this problem because both of these graphs have an equal slope!
They both have a leading coefficient of -1, which means their slopes are equal. Because of this, they are parallel.
Here is a fun fact: If two graphs have the same slope (number in front of x) and have different y-intercepts (b values/constants added/subtracted) then they are parallel.

The set of inequalities represented by x + y ≥ 3 is the Michael wants to buy enough cupcakes and fudge with his $15 to feed at least three siblings.
what is inequality ?A interaction between two expressions like values that is not equal is known as an inequality in mathematics. Inequality follows imbalance, therefore. In mathematics, an inequality makes a link among two values that do not equal. Egality and inequality are different. The not equal symbol is typically used to indicate that two values are also not equal (). Different inequalities are employed to contrast values of all sizes. By changing the two parts until only the variables are left, one can solve many straightforward inequalities. Negative values are split or added on either side. Switch between the left and right.

How do you prove the change of base formula?
The change of base formula states that for any logarithm base b and any positive number x: log_b(x) = (log_c(x)) / (log_c(b)), where c is any base.
The change of base formula is a mathematical formula that allows you to convert a logarithm with one base to a logarithm with another base. The formula states that for any logarithm base b and any positive number x: log_b(x) = (log_c(x)) / (log_c(b)), where c is any base.
One way to prove this is to use the properties of logarithms:
log_b(x × y) = log_b(x) + log_b(y)log_b(xⁿ) = n × log_b(x)Using these properties, we can write log_b(x) as:
log_b(x) = log_b([tex]c^{(log_c(x))}[/tex])
log_b(x) = log_b([tex]c^{(log_c(x))}[/tex]) / log_b(c¹)
log_b(x) = log_c(x) / log_c(b)
Therefore, the change of base formula is proven.

Why is the range of pixel values 0 255?
The range of pixel values in digital images is typically 0-255 because it corresponds to the number of bits used to represent each pixel. Most image file formats use 8 bits per color channel (red, green, and blue) to represent each pixel, and 8 bits can store a maximum of [tex]2^8[/tex] = 256 different values, with one of the values being reserved for transparency.
When working with 8-bit images, each color channel can take on one of 256 different values, from 0 to 255. This is known as an 8-bit color depth. Each pixel in the image is represented by a combination of red, green, and blue values, so the total number of possible colors is 256 x 256 x 256 = 16,777,216.
The use of 8-bit color depth allows for a wide range of colors to be represented in an image, while also being small enough to be easily stored and transmitted.
Also, it's worth mentioning that with the development of technology, the use of high-bit color-depth images has become more common in the field of photography, digital art, and video, where 16-bit and 32-bit color depths are frequently used.

Express the absolute value function f(x)=9|x| as a piecewise-defined function.
Answer:
[tex]f\left(x\right)=\begin{cases}-9x&x\: < \:0\\ \:\:\:9x&x > \:0\end{cases}[/tex]
Step-by-step explanation:
The first thing to note is that absolute value functions are piecewise functions.
A piecewise function is a function in which more than one formula is used to define the output over different pieces of the domain or inputs(in this case the x-values).
In this case, the absolute value function is
[tex]f(x) = 9|x|[/tex]
To write this function as a piecewise function you have to use the definition of [tex]f(x) = |x|[/tex] :
[tex]f\left(x\right)=\begin{cases}-x&x\: < \:0\\ \:\:\:x&x > \:0\end{cases}[/tex]
Applying this to [tex]9|x|[/tex] we multiply each of the parts by 9 to get
[tex]f\left(x\right)=\begin{cases}-9x&x\: < \:0\\ \:\:\:9x&x > \:0\end{cases}[/tex]
At [tex]|x| = 0, f(x) = 9|x| = 0\\[/tex]

Given Equations,
4x² + x - y = 0 ...(1)
-x² - 5x + y - 9 = 0
The above equation can be written as:
-x² - 5x + y = 9 ...(2)
Using the elimination method, the second term of both equations can be eliminated by adding the equations.
Therefore,
4x² + x - y = 0
-x² - 5x + y = 9

3x² - 4x = 9

[tex]x^{2} - \frac{4}{3}x + (\frac{2}{3}) ^{2} = 3 + (\frac{2}{3}) ^{2[/tex]
[tex]( x - \frac{2}{3})^{2} = 3 + \frac{4}{9}[/tex]
[tex]( x - \frac{2}{3})^{2} = \frac{31}{9}[/tex]
[tex]( x - \frac{2}{3}) = \sqrt{\frac{31}{9}}[/tex]
[tex]x = \frac{\sqrt{31} }{3} + \frac{2}{3} , - \frac{\sqrt{31} }{3} + \frac{2}{3}[/tex]
[tex]x = \frac{\sqrt{31} + 2 }{3} , \frac{-\sqrt{31} + 2 }{3}[/tex]
Now, Put the value of x in equation (1), we get the value of y.
4x² + x - y = 0
y = 4x² + x
[tex]y = 4( \frac{\sqrt{31} + 2 }{3})^{2} + \frac{\sqrt{31} + 2 }{3} , 4( \frac{-\sqrt{31} + 2 }{3})^{2} + \frac{-\sqrt{31} + 2 }{3}[/tex]
[tex]y = \frac{19\sqrt{31} + 146 }{9} , \frac{-19\sqrt{31} + 146 }{9}[/tex]
Therefore,
the values of x are [tex]\frac{\sqrt{31} + 2 }{3} , \frac{-\sqrt{31} + 2 }{3}[/tex] and y are [tex]\frac{19\sqrt{31} + 146 }{9} , \frac{-19\sqrt{31} + 146 }{9}[/tex].
