5. David has a credit rating of 750. Ethan has a credit rating of 630. David and Ethan apply for identical loans from First Bank. David is approved for a loan at 4.2% interest and Ethan is approved for a loan that charged 2
percentage points higher because of his inferior credit rating.
a. What interest rate is Ethan charged?
b. If you consider that David and Ethan took out loans for $6,000 to be paid back over 4 years, how much will
each end up paying in interest?

1/3 + 1/3 ≠ 2/6 because 1/3 alone = 2/6  

step by step explanation:

1/3 + 1/3 = 2/3       2/3=4/6

80

step-by-step explanation:

answer: it is a.,b.,d.

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.
