Answer: I don't know
Step-by-step explanation:
Answer:
Y=3x+5
Step-by-step explanation:
If we take x = 1, according to the first function (the answer) y would be 8.
Other options:
—————
Formula 3:
Y= 2^x+5 == 7
Formula 4:
Y = x+8 == 9
True answer = 10.
——————
Ok, so the last one seems more accurate lets test the first and last one on two more numbers:
——————
X = 15
Formula 1:
50
Formula 4:
23
True answer = 60.
The first formula wins.
————————-
X= 10
Formula 1:
35
Formula 4:
18
True answer = 41
The first formula wins.
——————
So, we can see that the first formula is most accurate.

Answer:
a). m∠AED = 70°
b). x = 10°
Step-by-step explanation:
a). Quadrilateral ABDE is a cyclic quadrilateral.
Therefore, by the theorem of cyclic quadrilateral,
Sum of either pair of opposite angle is 180°
m(∠AED) + m(∠ABD) = 180°
m(∠AED) = 180° - 110°
m(∠AED) = 70°
Since, ∠AED ≅ ∠EAD
Therefore, m∠AED = m∠EAD = 70°
b). By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
110° + 40° + m∠DAB = 180°
m∠DAB = 180° - 150°
m∠DAB = 30°
m∠BAE = m∠EAD + m∠BAD
= 70° + 30° = 100°
By angle sum theorem in ΔACE,
m∠EAC + m∠AEC + m∠ACE = 180°
100° + 70° + x° = 180°
x = 180° - 170°
x = 10°
