Boundary lines are dotted whenever the sign is strictly greater than or less than.
The only reason a line is not dashed would be that it would be equal to. A quick way to remember this would be that the extra line provided to make it equal would fill in the blanks. Hope this tip helps you, helped me ace many tests!
Answer:
x = 2 | y = 3. ( 2,3 )
Step-by-step explanation:
2(3x + 3y = 15)
6x + 6y = 30
3(4x + 2y = 14)
12x + 6y = 42
- 6x. -6y. -30
6x = 12
÷ 6. ÷6
x = 2
3x + 3y = 15
3(2) + 3y = 15
6 + 3y = 15
-6. -6
3y = 9
÷3. ÷3
y = 3
Using similar triangles, the proportionality ratio of △QRS to △KJI is of 1/3.
<h3>What are similar triangles?</h3>
Similar triangles are triangles that have the same angles, and whose side lengths are proportional.
For this problem, we have that:
- The sides that have length of 2 on △QRS have lengths of 6 on △KJI.
- The side that has a length of 1 on △QRS has length of 3 on △KJI.
Hence the proportionality ratio of △QRS to △KJI is given as follows:
2/6 = 1/3.

Answer:
a) m∠FGH= 28°
b) m∠HGI = 28°
c) m ∠FGI = 56°
Step-by-step explanation:
GH bisects ∠FGI. So, ∠FGH = ∠HGI
5x - 2 = 6x -8
5x - 6x = 2 - 8
-x = - 6
x = 6
a) m∠FGH = 5x - 2 = 5 * 6 - 2 = 30 - 2 = 28°
b) m∠HGI = 6x - 8 = 6 * 6 - 8 = 36 - 8 = 28°
c) m ∠FGI = m∠FGH + m∠HGI = 28° +28° = 56°
