Answer:
Step-by-step explanation:
When x = 3, y = 13
When x = 5, y = 37
Subtract both y-values to find the change:
37 - 13 = 24
Average of the change:
= 12
Answer:
Step-by-step explanation:
The equation given is:
Using quadratic formula:
From the question:
a = 2, b = -4, c = 7
Therefore:
=>
Is the equation suppose to be f(x)=x^2 and g(x)= x+5^2-9? the triangle thing means to the power of
Answer: -9°F
Step-by-step explanation:
From the question, we are told that the temperature at 6:00 am was -12 Fahrenheit and that the temperature increased by 1/2 Fahrenheit each hour for 6 hours.
The temperature, in degrees Fahrenheit, at noon would be:
= -12°F + 1/2(6)
= -12°F + 3°F
= -9°F
