Answer:
B. 57°F
Step-by-step explanation:
Given:
F = n/4 + 37
Where,
F = temperature in degrees Fahrenheit
n = number of times per minute crickets chirps
Find F when n = 80
F = n/4 + 37
F = 80/4 + 37
= 20 + 37
= 57
F = 57 °F
B. 57 °F
This is the graph that the equation shows:
Answer:
The answer to your question is: (5/2, -6)
Step-by-step explanation:
Given f(x) = (6x - 36) / (2x² - 17x + 30)
Factorize both, numerator and denominator
Numerator = 6(x - 6)
Denominator = 2x² - 12x - 5x + 30
= 2x(x - 6) - 5(x - 6)
= (x - 6) (2x - 5)
Now f(x) = 6(x - 6) / (x - 6) (2x - 5) Cancel (x - 6)
f(x) = 6 / 2x - 5
Find the hole 2x - 5 = 0
2x = 5
x = 5/2
In 5/2 there is a hole, in y is approximately -6
The answer is 2 weeks but he needs it before the 8 weeks so I would say 1 week and 6 days.
