Answer:
Step-by-step explanation: X1=-8,Y1=1, M=5/6.
Using the formular y-y1=m(x-x1)
y-1=5/6(x-(-8)
=y-1=5/6(x+8)
y-1=5x+8/6
=6(y-1)=5x+8
6y-6=5x+8
6y-5x=8-6
6y-5x=2
A sextant<span> is a </span>doubly reflecting navigation instrument<span> that measures the </span>angular distance<span> between two visible objects. The primary use of a sextant is to measure the angle between an </span>astronomical object<span> and the </span>horizon<span> for the purposes of </span>celestial navigation<span>.
The estimation of this angle, the altitude, is known as </span>sighting<span> or </span>shooting<span> the object, or </span>taking a sight<span>. The angle and the time when it was measured, can be used to calculate a </span>position line<span> on a nautical or aeronautical </span>chart. F<span>or example; sighting the </span>Sun<span> at </span>noon <span>or </span>Polaris<span> at night (in the Northern Hemisphere) to estimate </span>latitude<span>. Sighting the height of a landmark can give a measure of </span>distance off<span> and held horizontally.
A sextant can measure angles between objects for a </span>position on a chart.<span> A sextant can also be used to measure the </span>lunar distance<span> between the moon and another celestial object (such as a star or planet) in order to determine </span>Greenwich Mean Time<span> and hence </span>longitude<span>.

Answer:
x = 24.
Step-by-step explanation: given lines s and t are parallel and line m is a bisector, we can conclude that (2x+27) is an opposite exterior angle and congruent to the angle adjacent to (4x+9). Defining those 2 angles are supplementary, they = 180 degrees. Therefore, 2x+27+4x+9=180. Subtract 36 (27+9) from the left side of the equation as well as from the right side (180-36) you get 2x+4x=144. Add the x's you get 6x. So, 6x=144. Divide both sides by 6 and you get x=24.
Hope that helps
Answer:
x = 1
Step-by-step explanation:
The graph shows the curves cross at x=1.
The solution is x = 1.

I personally find it more convenient to look for the zeros (x-intercepts) of the difference f(x)-g(x). That way, I'm only graphing one function, and I don't have to look all over the graph to try to find the point of intersection. (The solution is always on the x-axis.) The attached graph shows f(x) - g(x) as a dashed green line.
