А Julian is working two summer jobs, making $8 per hour washing cars and making
$13 per hour tutoring. In a given week, he can work a maximum of 13 total hours and
must earn no less than $130. If x represents the number of hours washing cars and y
represents the number of hours tutoring, write and solve a system of inequalities
graphically and determine one possible solution.

b

step-by-step explanation:

the answer would be c:   ax + b = ax + c

step-by-step explanation:

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.
