Answer:
A) N1 = 4*N2 OR N1 -4*N2 = 0
B) N1 + N2 = 155 multiplying B) by -1
B) -N1 -N2 = -155 then adding equation A)
A) N1 -4*N2 = 0 adding the 2 equations
-5*N2 = -155
The numbers are N2 = 31 N1 = 124
Step-by-step explanation:
It's none of those, but the last is quite close to the exact value. You can find approximate square roots by trial and error: for sqrt(8), 2 is too small and 3 is too big, so try 2.5, 2.6, 2.7, 2.8, and 2.9. You'll find the answer is between 2.8 and 2.9.
Using the slope concept, it is found that the distance the plane traveled from point A to point B is of 14,475 feet.
<h3>What is a slope?</h3>
- The slope is given by the <u>vertical change divided by the horizontal change</u>.
- It's also the tangent of the angle of depression.
At point A:
- Altitude of 6700 feet, which is the vertical change.
- The horizontal position we want to find is
.
Hence:



At point B:
- Altitude of 6700 feet, which is the vertical change.
- The horizontal position we want to find is
.
Hence:



Then, the distance is of:

Answer:
substitution method
x = 7
y = 2
Step-by-step explanation:
2x - 2y = 10
x = 7
substitute for x:
2(7) - 2y = 10
14 - 2y = 10
subtract 14 from each side of the equation:
-2y = -4
divide both sides by -2:
y = 2
