If D is the midpoint of EG, find the length of EG
Brrunno [24]

ED = x - 5 <em>given</em>

DG = 4x - 38 <em>given</em>

ED = DG <em>definition of midpoint</em>

x - 5 = 4x - 38 <em>substitution</em>

-5 = 3x - 38 <em>subtraction property of equality (subtracted x from both sides)</em>

33 = 3x <em>addition property of equality (added 38 to both sides)</em>

11 = x <em>division property of equality (divided 3 from both sides)</em>

ED = x - 5 → ED = 11 - 5 → ED = 6 <em>substitution</em>

since ED = DG, then DG = 6 <em>transitive property</em>

ED + DG = EG <em>segment addition property</em>

6 + 6 = EG <em>substitution</em>

12 = EG <em>simplified like terms</em>

Answer: 12

Determine whether the function f(x) = 0.25 (2x - 15)^2 + 150 has a maximum or minimum.
AnnyKZ [126]

Answer:

minimum

Step-by-step explanation:

Given a quadratic function in vertex form

f(x) = a(x - h)² + k

• If a > 0 then f(x) is a minimum

• If a < 0 then f(x) is a maximum

f(x) = 0.25(2x - 15)² + 150 ← is in vertex form

with a = 0.25 > 0

Thus f(x) has a minimum turning point
