Answer:
16) 
17) y = -x - 4
18) y = -2x - 1
19) y = -2x
20)
Step-by-step explanation:
With the two points you find the slope using 
Then using that slope, plug the slope in with one of the points values of x and y into the point slope formula, and smiplify that into the y-intercept formula.
Answer:
-5 Faces
-10 Edges
-6 Vertices
Step-by-step explanation:
Folded out there are 3 rectangles and 2 triangles, 5 faces
Count the straight lines, no dotted, it's 10 edges
Count the corners only and the top of the triangles 6 vertices
Why is this so hard i cant even solve it i need someone to answer this to
Answer:
False
Step-by-step explanation:
Absolute value gives you a positive answer
Okay, here we have this:
Considering the provided information we are going calculate how far is the plane from the airport, so we obtain the following using the law of cosines:
![\begin{gathered} a=\sqrt[]{120^2+150^2-2\cdot120\cdot150\cdot\cos (129.17)} \\ a\approx244\text{ miles} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20a%3D%5Csqrt%5B%5D%7B120%5E2%2B150%5E2-2%5Ccdot120%5Ccdot150%5Ccdot%5Ccos%20%28129.17%29%7D%20%5C%5C%20a%5Capprox244%5Ctext%7B%20miles%7D%20%5Cend%7Bgathered%7D)
Finally we obtain that the plane is approximately 244 miles far from the airport.
