From the information given, determine which triangles, if any, are congruent and state by which rule. If the triangles cannot be shown to be congruent, write, "Cannot be determined," and explain.

Cannot be determined

Step-by-step explanation:

The triangles are not congruent because it follows the pattern Side-Side-Angle, and the triangles are not right triangles, so they cannot be congruent by hypotenuse-leg. Side-Side-Angle is not a congruent rule. It is only Side-Angle-Side, Angle-Side-Angle, or Side-Side-Side.

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
