Answer:
b
Step-by-step explanation:
Because y is squared, or, actually, because (y + 6) is squared, we know immediately that the graph is horizontal. Because both (y + 6)^2 and (x - 7) are positive, we know that the graph opens to the right. (b) is correct.
Answer:
99 degrees
Step-by-step explanation:
81+a=180, so
180-81=99
a=99
64.50-.10=64.40
64.40-47=17.4
(my way of working math when i'm not in school is weird, but still accurate)
17.4/4=4.35.
It's average change per day is -4.35.
