The solutions to an algebraic equation equal the highest power in that equation. So, in this case, the answer is 23.
Answer:
Imagine is quite blurry. Could you possibly zoom in for further assistance.
Step-by-step explanation:
The temperature needs to fall 14 dregrees Fahrenheit to get to the original temperature 68 degrees Fahrenheit.
X^2 + x - 6
------------- <= 0
x - 7
(x + 3)(x - 2)
---------------- <= 0
x - 7
2 critical values are x = -3 and x = 2
if x <= -3 the the function <= 0 so that's one part of the solution
also x >= 2
x must be < 7 if its = 7 then the function is indeterminate. and values between 2 and 7 will give negative valu to function
The answer is choice A.
