Answer:One way of knowing the correct answers, we substitute the ordered pairs to the function and see whether it would make the function true.
3x – 4y = 21
A. (−3, 3)
3(-3) – 4(3) = 21
-21 = 21 ---------------> not equal
B. (−1, −6)
3(-1) – 4(-6) = 21
21 = 21 ---------------> equal
C. (7, 0)
3(7) – 4(0) = 21
21 = 21 ---------------> equal
D. (11, 3)
3(11) – 4(3) = 21
21 = 21 ---------------> equal
Answer:
108 children were drinking apple juice. $432 were spent on pizza.
Step-by-step explanation:
How many children were drinking apple juice:
567 - 323 - 136 = 108
How many children were eating pizza:
108 * 2 = 216
How much was spent on pizza:
216 * $2 = $432
Answer:
138
Step-by-step explanation:
Hexagon total angle = 720
170+ 277 + 135 = 582
720 - 582 = 138
Answer:
55
Step-by-step explanation:
The n-th term of an arithmetic sequence is given by the formula ...
an = a1 + d(n -1)
where a1 is the first term (5.5) and d is the common difference (0.5).
So, the n-th term is ...
an = 5.5 +0.5(n -1) = 5.0 +0.5n
For n = 100, the term is ...
a100 = 5.0 +0.5(100) = 55
The 100th term of the sequence is 55.
