The coordinate plane below represents a city. points a through f are schools in the city.

part a: using the graph above, create a system of inequalities that only contain points b and c in the overlapping shaded regions. explain how the lines will be graphed and shaded on the coordinate grid above.

part b: explain how to verify that the points b and c are solutions to the system of inequalities created in part a.

part c: lisa can only attend a school in her designated zone. lisa's zone is defined by y > 2x + 5. explain how you can identify the schools that lisa is allowed to attend.

so, converting firstly the mixed fractions to improper fractions and then "adding".

b

step-by-step explanation:

u take $75 minus $60.the anwer/original($75)multiply by 100

answer:   the paragraph proof is mentioned below.

step-by-step explanation:

given: in a δxwy where

such that, ∠wzx ≅ ∠yzx and zw≅zy

we have to prove that: segment zx is a perpendicular bisector of segment wy.

prove: since, zw≅zy ⇒ ∠wzy is a supplementary angle.

then, ∠wzy= 180°

⇒∠wzx + ∠yzx = 180° ( because xz divides ∠wzy into two parts)

but, ∠wzx ≅ ∠yzx ( given)

⇒∠wzy+∠wzy=180° ( by substitution)

⇒2∠wzy=180°

⇒∠wzy=90°

⇒∠wzy=∠yzx =90°

therefore, xz⊥wy where wz=zy

⇒zx is a perpendicular bisector of wy.
