This is late, but for anyone else that needs it, it's B. 4x-5
You can set each equation to 0 so it would look like this:
And solve
4n+5=0. 3n-7=0
-5=-5. +7=+7
4n = 5. 3n = 7
4n/4 = 5/4. 3n/3 = 7/3
n = 5/4 n = 7/3
The first set of answers are the correct answers for n.
Answer:
yes
Step-by-step explanation:
To determine if the point lies on the line substitute the coordinates into the left side of the equation and if equal to the right side then the point lies on the line
- 3 + (4 × 4) = - 3 + 16 = 13 = right side
Hence (- 3, 4) lies on the line x + 4y = 13
We are given with the length of the kite string of 80 meters and an angle of 75 degrees of the string with the ground. In this situation, the kite string is the hypotheneuse of the triangle and 75 degrees is the angle of elevation. The height of the kite from the ground is 80 sin 75 or 77.27 meters.
