Airlines have increasingly outsourced the maintenance of their planes to other companies. A concern voiced by critics is that th
irinina [24]

According to the information that is found in a different source, the recent data does not support the concerns of the critics. These are the numbers shown in the data:

<u>Airline / Outsource Percent / Delay Percent</u>

<em>Alaska</em> / 51.0 / 10.35

<em>American</em> / 29.4 / 20.32

<em>Delta</em> / 36.7 / 14.48

<em>Frontier</em> / 46.3 / 21.42

<em>Hawaiian</em> / 78.4 / 5.06

Based on this data, we can see that the critics do not seem to be justified in their concerns. We can see that airlines have outsourced much of the maintenance of their planes, but that there does not seem to be a strong correlation between this outsourcing and the percentage of delays. For example, the airline that outsources the most is Hawaiian (78.4%), yet it has the lowest percentage of delayed flights (5.06%).

Naily [24]

Hi there!  

»»————- ★ ————-««

I believe your answer is:  

(-2, 0)

»»————- ★ ————-««  

Here’s why:  

⸻⸻⸻⸻

\text{Substitute in \textbf{0} for } y \text{ and solve for } x\text{.}\\-------------------\\y = 2x+4\\-------------------\\\rightarrow 0 = 2x +4\\\\\rightarrow 2x + 4 = 0\\\\\rightarrow 2x +4 - 4 = 0 - 4\\\\\rightarrow 2x = -4\\\\\rightarrow\frac{2x=-4}{2}\\\\\rightarrow \boxed{x=-2}

⸻⸻⸻⸻

\text{The \textbf{x-intercept} of the given equation is: } (-2, 0)

⸻⸻⸻⸻

Hope this helps you. I apologize if it’s incorrect.
