Y=-3x+10 if you take the negative reciprocal and plug in the point to solve for b.
Answer:
Step-by-step explanation:
Use the cosine rule and see if the numbers hold true. a^2 = b^2 + c^2 - (2bc (cos x))
By substituting in our values I get that cos x = 0.838... which is possible. If cos x would equal 1.5, the there is no solution and the triangle would not be possible.
Answer:
Step-by-step explanation:
((615/100)x+(24/100)y)/(15/10)+(59/10)x-(16/10)y
Final result :
2 • (125x - 18y)

Answer:
0.0021 in scientific notation is ![\mathbf{2.1 x 10 ^ {-3}}](https://tex.z-dn.net/?f=%5Cmathbf%7B2.1%20x%2010%20%5E%20%7B-3%7D%7D)
Step-by-step explanation:
We need to write 0.0021 in scientific notation.
<u>Scientific Notation:</u><u> A number expressed in scientific notation is written when numbers between 1 to 10 are multiplied by a power of 10.</u>
In the given example 0.0021 our decimal will be shifted to the right 3 digits and the power will be negative 3 (-3)
So, 0.0021 in scientific notation is ![\mathbf{2.1 x 10 ^ {-3}}](https://tex.z-dn.net/?f=%5Cmathbf%7B2.1%20x%2010%20%5E%20%7B-3%7D%7D)
Answer:
The y-int represents the base price of $200 for airfare from NYC
The slope represents a cost of 30 cents per mile traveled
If the base cost for airfare changed to $50 and the cost per mile is unchanged, the new equation would be y=50+0.30x
If the cost per mile changed to 50 cents, the new equation would be y=200+0.50x
