Answer:

Step-by-step explanation:
Equilateral triangles have 3 equal sides.
Thus, perimeter of triangle
= 3(2x -3)
= 3(2x) +3(-3) <em>(</em><em>expand</em><em>)</em>
= (6x -9) inches
Given that the perimeter is 83 inches,
6x -9= 83
6x= 83 +9 <em>(</em><em>+</em><em>9</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>)</em>
6x= 92

Answer:
(b) the answer
Step-by-step explanation:
<u>Using y = mx + b</u>
8y = 4x - 16 ⇒ y =
- 2
-x = -2y - 4 ⇒ 2y - x = - 4 ⇒ 2y = x - 4 ⇒ y =
- 2
Since the equations have the same slope (
) and y-intercepts (-2), then they are the same line. Thus, they intersect at every point so have infinite solutions.
