Answer:
Check the solution in both equations. The solution is ( − 1, 2). Solve the system by graphing: {− x + y = 12 x + y = 10 . Solve the system by graphing: {2x + y = 6 x + y = 1 . In all the systems of linear equations so far, the lines intersected and the solution was one point.

In a triangle, the total measure of the interior angles is 180 degrees.
26 + 98 + x = 180
124 + x = 180
x = 56 degrees
The measure of the third angle is 56 degrees.
Hope this helps!! :)
Answer:
8.1 * 10^-2
Step-by-step explanation:
Scientific notation is a number with it's largest digit in the one's place and its succeeding digits following it as decimals, then multiplied by a power of ten.
Appling this knowledge to the given number, we can conclude:
0.0810
= 0.081
= 8.1 * (1/10) * (1/10)
= 8.1 * 10^-1 * 10^-1
=9.1 * 10^-2
