Answer: 9x+16
Step-by-step explanation: in image below
The values of the domain are:
D: {1, 3, 5, 7}
The values of the range are:
R: {2, 4, 6, 8}
When we find the inverse of the function, then the domain and the range are reversed.
Therefore, we have that for T ^ -1 (x):
The domain is:
D: {2, 4, 6, 8}
The range is:
R: {1, 3, 5, 7}
Answer:
The inverse of T (x) is:
option B
Answer:
∠DAB = 80°
∠BAC = 105°
Step-by-step explanation:
You are given ...
∠DAC = 25° = (x -20)°
Adding 20°, we have ...
x° = 45°
Then the measures of the other angles are ...
∠DAB = (2x -10)° = 2(45°) -10°
∠DAB = 80°
and
∠BAC = ∠DAB +∠DAC = 80° +25°
∠BAC = 105°
_____
Nothing in this problem statement defines a circle.
Substitute the value of a = -2 to the expression -3(6a + 4):
-3(6 · (-2) + 4) = -3 · (-12 + 4) = -3 · (-8) = 24
