A (solution) is a point of intersection. If the lines have different slopes then they will have one solution. If they have the same slope, then they will have either infinite or no solutions, depending on the y intercepts.

These equations have different slopes, therefore the system has 1 solution.

Which values of x in the interval 0 x 360 satisfy the equation 2sin^2x+sinx-1=0?

Temka [501]

Factor first: (sinx+1)(2sinx-1)=0
sinx+1=0 or 2sinx-1=0
sinx=-1 or sinx=1/2
0≤x≤360, so x=270, or x=30 or x=150
