Answer:
27 degrees
Step-by-step explanation:
it was at 18 and then it went down 27 degrees to get to -9 because if you take away the - sign in negative -9, and ad 9 to 18 you will get 27 or just use the calculator to double check your work (what i did) 18-27=-9 and thats what the tempurture went down to in 8 hours
Answer:
Step-by-step explanation:
(1) To solve by factoring,
Given equation:
Subtract 9 from both sides of the equation.
Using zero factor principle,
The solutions are .
(2) To solve by complete the square
,
Given
Divide both sides of the equation by 4.
Square root on both sides.
(3) To solve by quadratic formula,
Here, a = 4, b = 0, c = –9
Quadratic formula,
I would have to say that the next step would be to add the x so that way you are able to have your number on one side and your x variable on the other.

The value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.
<h3>What is polynomia?</h3>
To calculate the polynomial expression below, we use the technique below.
From the question,
Given:
- f(t) = 2t³.............. Equation 1
To find f(4) we substitute 4 as the value of x in equation 1
To find 3[f(t)] we multiply equation 1 by 3
Hence, the value of f(4) and 3[f(t)] if f(t) = 2t³ is 512 and 6t³ respectively.
