Answer:
y = 8x + 10 and y = (1/8)x + 10 are intersecting lines.
4x + 10y = 6 and y = (5/2)x + 7 are perpendicular lines.
x + y = 5 and 7x + 7y = 14 are parallel lines.
y = 2x + 8 and -y = -2x + 6 are parallel lines.
y = 8x + 10 and y = -(1/8)x + 10 are perpendicular lines.

Answer:
5. x=21.9 units
6. x=14 units
7. x=31.7 units
Step-by-step explanation:
5. Assuming that the line through the middle of the triangle in 5, we can split the 18 units side into 9 and 9. Using pythagorean theorem (a^2+b^2+c^2), we can find that x is equal to making x . Rounding to the nearest tenth, we get x is about 21.9 units
6. By doing pyth. th. on one of the triangles, we get sqrt(361-289) which is sqrt(72), which is about 8.5 units. Subtracting 8.5*2 from 31, we get 14 for x
7. by doing pyth th on the smaller triangle, we get sqrt 228 and now we can do pyth th again with 28 (44-16) and sqrt228, which turns out to be sqrt (784+228) which is sqrt (1002), which when rounded the nearest tenth is 31.7
Good Luck!
