Answer:
(D)R: x+2=7
Step-by-step explanation:
Given the statement P:x=5
An equivalent statement will be a statement whose result is exactly x=5.
From the given options:
R: x+2=7
R: x=7-2
R: x=5
Therefore, R is an equivalent statement.
The correct option is D.
We need to know this:
If Δ > 0 we have two and different solutions
If Δ = 0 we just one solution
If Δ < 0 we don't have real solutions
This is a ceiling function. First points should be empty.
The first point x=-3, f(-3)= -6
The last point x=3, f(3)=0
Answer is bottom, left.
The answer is C. From the solution in the picture
