The solution is the point where the two lines intersect (are equal) so y=y and we can say:
6-x=-10-x upon adding x to both sides:
6=-10
This is never true so there is no solution to this system of equations. And for this to be true the two lines must be parallel and have different y-intercepts...
Answer:
a ≠ 2
Step-by-step explanation:
Given
The denominator of the rational function cannot be zero as this would make it undefined. Equating the denominator to zero and solving gives the value that a cannot be, that is
- 3a + 6 = 0 ( subtract 6 from both sides )
- 3a = - 6 ( divide both sides by - 3 )
a = 2 ← excluded value
A) Angle 1 + Angle 2 = 180
B) Angle 1 - Angle 2 = 16
Adding both equations:
2 * Angle 1 = 196
Angle 1 = 98
Angle 2 = 82
Answer:
The roots are the x-intercepts, where the parabola crosses the x-axis. If the parabola opens up and it's vertex is below the x-axis then it crosses the x-axis in two places and has two (real) roots.
Step-by-step explanation:
R - 18 = 50
r = 50 + 18 = 68
Hence Rick is 68 yrs old
