Find the inverse relationship of the function y=2x+5

daser333 [38]

Answer:

y=x-5/2

Step-by-step explanation:

Swap y and x

x=2y+5

since a function has to be in the form y=mx+c

take 5 to the other side in order to remain with 2y then divide both sides by 2

x-5/2=y

y=x-5/2

Answer:

$\overline{BC} \cong \overline{DC}$ because corresponding parts of congruent triangles ΔACD and ΔACB are Congruent

Step-by-step explanation:

Statements, Reason

$\overline{AC}$ bisects ∠BCD, Given

$\overline{DC} \perp \overline{AD}$ Given

∠CDA ≅ ∠CBA Right angles are ≅

$\overline{AC} \cong \overline{AC}$ Reflexive property

ΔACD ≅ ΔACB Hypotenuse Leg (HL) congrurency

$\overline{BC} \cong \overline{DC}$ CPCTC

Where:

CPCTC = Corresponding parts of Congruent Triangles are Congruent

⊥ = Perpendicular to

≅ = Congruent

∠ = Angle

Δ = Triangle.
