Answer:
A. {-1, 0, 5, 10}
Step-by-step explanation:
Given:
(-1, 1), (0, -1), (5, -11), (10, -21)
Required:
Domain of the set of the above ordered pairs
SOLUTION:
Domain of any set of ordered pairs includes all the x-values in the set of ordered pairs, while the y-values in the set of the ordered pairs makes up the range.
The first value in an ordered pair is the x-value while the second is the y-values, i.e. (x, y).
Therefore, the domain for the given set of ordered pairs is:
{-1, 0, 5, 10}.
The correct option is A.
Answer:
∠ ADC = 100° , ∠ DCB = 39°
Step-by-step explanation:
(3y + 7) and ( 3y - 13) are angles on a straight line and sum to 180° , so
3y + 7 + 3y - 13 = 180
6y - 6 = 180 ( add 6 to both sides )
6y = 186 ( divide both sides by 6 )
y = 31
Then
∠ ADC = 3y + 7 = 3(31) + 7 = 93 + 7 = 100°
and
∠ BDC = 3y - 13 = 3(31) - 13 = 93 - 13 = 80°
∠ BDC = 180° - (61 + 80)° ← angle sum in Δ BCD = 180°
= 180° - 141°
= 39°
