Answer:
3
Step-by-step explanation:
Let the missing number be
.
Then we have 
We expand the right hand side to get:

By comparing constant terms we get:

Divide both sides by -15

Therefore the missing number is 3
Answer:
f(x)=3x−1
2
Step-by-step explanation:
The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined. The range is the set of all valid y values. The domain of the expression is all real numbers except where the expression is undefined. In this case, there is no real number that makes the expression undefined.

Answer:
The answer is that Regina is absolutely right
Step-by-step explanation:
Hello!
The answer is that Regina is absolutely right, this is because the fundamental theorem of algebra states that every polynomial equation has the same number of solutions as its highest exponent, for this case it is 2. Therefore, there are two values of X that cause the equation to result in zero

Complete Question:
The temperature doubled. Evaluate when t = 32 degrees.
The value of the expression when t = 32 degrees is degrees
Answer:
64 degrees
Step-by-step explanation:
Given

Required
Determine the value of t when it doubles
To do this, we simply multiply the current temperature by 2.
So:
becomes


<em>Hence, the temperature when it doubles is 64 degrees</em>
