Answer:
1 3/4
Step-by-step explanation:
5/4 + 1/2
Get a common denominator of 4
5/4 * 1/2 *2/2
5/4 + 2/4
7/4
Rewriting as a mixed number
4/4 + 3/4
1 3/4
Answer:

Step-by-step explanation:
The nth term of an arithmetic sequence is given by the formula:

Where
a is the first term
d is the common difference
a is given as 12
To find d, we subtract any term from the term after it. So
d = 16 - 12 = 4
Now, the explicit formula for nth term is:

Answer:
y = 2 - 
Step-by-step explanation:
results in a parabola (U-shape). Adding a negative in front of it flips the parabola to look like an upside-down U.
The 2 makes it shift up two decimal spots to (0,2).
Answer:
e=g = 126 degree
Step-by-step explanation:
e = g (opposite angles's property)
g+ b = 180 ( supplementary angles's property)
b = 54 degree (opposite angles's property)
-> g = 180-54 = 126
-> e = 126 degree
