Answer:
B: swap the order of the equations
(Yes) they have the same solution
Step-by-step explanation:
The sum of the interior angles of any polygon is (n-2)*180° (n being the number of sides) so for a triangle the sum of the interior angles is 180°. The sum of the interior and exterior angles is also 180°. To work out which sets are possible you subtract each number from 180° and then add all three answers together. If you get 180° then that set of numbers is possible. Using this method, you will find that the following sets <span>can be the measures of the exterior angles of a triangle:
</span><span>120°, 110°, 130°
</span><span>120°, 120°, 120°</span>
Parallel lines have the same slope but different y-intercepts. Which answer has the same slope as the one above? Hint: m is the slope (coefficient of x)
C. It would need to be more than 30 hundredth in order to be greater than 4.3
Answer:
C. Yes, because every x- and y-value is positive
