Answer:
there's no solution.
Step-by-step explanation:
if y = 3x -4 then use this instead of y in the second equation
9x -3(3x+4) = 14 ➡9x-9x -12 = 14 9x will eliminate -9x and -12 can't be = 14 so there's no solution
The length of the pencil would be 17. This could be easily found by using a^2 + b^2 = c^2. Please mark me brainliest it would be pretty cash money of you
Answer:
The angle that the ramp makes with the ground is 11.54°
Step-by-step explanation:
From the image attached, we can see that the length of 17 1/2 ft corresponds to the hypotenuse in a right triangle, the length of 3 1/2 ft corresponds to the opposite side.
We can use the fact that the sin(θ) =
to find the angle that the ramp makes with the ground.
![sin(\theta)=\frac{3.5}{17.5}](https://tex.z-dn.net/?f=sin%28%5Ctheta%29%3D%5Cfrac%7B3.5%7D%7B17.5%7D)
The angle is equal to
![\theta = sin^{-1}(\frac{3.5}{17.5} )\\\theta = 11.54\°](https://tex.z-dn.net/?f=%5Ctheta%20%3D%20sin%5E%7B-1%7D%28%5Cfrac%7B3.5%7D%7B17.5%7D%20%29%5C%5C%5Ctheta%20%3D%2011.54%5C%C2%B0)
