Answer:
f(x) = - 4x² + 24x - 20
Step-by-step explanation:
Given
f(x) = - 4(x - 3)² + 16 ← expand the factor using FOIL
= - 4(x² - 6x + 9) + 16 ← distribute parenthesis by - 4
= - 4x² + 24x - 36 + 16 ← collect like terms
= - 4x² + 24x - 20
Answer:
It is open.
Step-by-step explanation:
Open inequalities entail signs like 
, while closed inequalities entail signs like 
instead.
Answer:
[See Below]
Step-by-step explanation:
✦ First change the improper fractions to decimals:
✧ ⁵⁄₄ = 1.25
✧ -⁹⁄₅ = -1.8
✦ Then divide:
✧ 1.25 ÷ -1.8 = -0.69
So x would be -0.69 in decimal form.

Angle AOD and < BOD are supplementary since they are both right angles which equal 180°.
<h3>What is a supplementary angle?</h3>
It should be noted that a supplementary angle simply means an angle that adds up to 180°.
In this case, the angles given are both rights angles. This will be:
= 90° + 90°
= 180°
In this case, Angle AOD and < BOD are supplementary since they are both rights angles which equal 180°.
