4 : 8
x 9 => 36 : 72 <=== equivalent
Triangles ABC and DEF may or may not be congruent, because the angle-angle-angle (AAA) postulate is not a criterion for congruency of any two triangles. This is because the angle-angle-angle postulate only incorporates the angles of the triangles, and the side lengths are not specified, so congruency may or may not be true for these triangles.
Answer:
x = 8
Step-by-step explanation:
combine like terms:
18x + 36 = 180
18x = 180-36
18x = 144
x = 144/18
x = 8
Answer:
y = -3/4x + 4
Step-by-step explanation:
y = mx + b
-2 = (-3/4)(8) + b
-2 = -6 + b
4 = b
y = -3/4x + 4
