B. Should be the correct answer
Step-by-step explanation:
0 = sqrt(x - 4) + 3 Set equation equal to 0
-3 = sqrt(x - 4). Subtract 3 from both sides
the principle square root will only output positive values, since if it every outputted a negative value it would not be a function since a function cannot have 2 outputs for the same input.
no x-intercept
Neck: In 2/3 of an hour Naomi will stretch her neck one (there's not enough time for two neck stretches, that would require an hour).
Legs: In 2/3 of an hour, she will stretch her legs twice (1 stretch every 1/3 of an hour for 2/3 of an hour equals 2).
Arms: In 2/3 of an hour she will stretch her arm four times (2/3 divided by 1/6 equals 4).
Total stretches: 1 neck stretch, 2 legs stretches, and 4 arms stretches.
260/500= 26/50= 13/25 is the answer to the question
(3b) / (5b - 7) = 8/11
cross multiply
8(5b - 7) = 11(3b)
40b - 56 = 33b
-56 = 33b - 40b
-56 = -7b
-56/-7 = b
8 = b
