Answer:
The bottom left system of equations has no solutions.
Step-by-step explanation:
A solution to the system of equations is a point where the graphs of equations intersect, because the intersection point represents a point that is common to both equations; Therefore, a system that has no solutions, will have graphs that will never intersect.
Now, looking at the 4 graphs given, we see that the upper-left graph represents lines which intersect; therefore, this system has a solution.
The upper-right graph represents only one equation and not a system—it could well be that the red line hides another line that is exactly beneath it, in which case the system would have infinitely many solutions.
The bottom-left graph represents lines that are parallel—they are never going to meet; therefore, this system has no solutions.
The bottom-right graph represents lines that have a point of intersect, and therefore, have a solution.
Thus only the bottom-right graph has no solutions.

EXPLANATION
The acute angle given in the right triangle is 27°.
The side length adjacent to the 27° angle is 34 units.
The side length we want to find is x units, which is the hypotenuse of the right triangle.
We use the cosine ratio to obtain:
Solve for x,
to the nearest hundredth.
Answer:
n=-9
Step-by-step explanation:
c is the number in the sequence and n is the number you have to multiply by. If the c is 8 you would do -9 times 8.
128*.69=88.32-8.83
128+8.83=136.83
Answer choice B is the answer.
