Answer:

And solving we have:


And we can write the expression like this:

The vertex for this case would be:

And the minimum for the function would be 3 and there is no maximum value for the function
Step-by-step explanation:
For this case we have the following equation given:

We can complete the square like this:

And solving we have:


And we can write the expression like this:

The vertex for this case would be:

And the minimum for the function would be 3 and there is no maximum value for the function
Answer:
<h2>
RS = 47</h2>
Step-by-step explanation:
RV=VU and SW=WT ⇒ 
Therefore:

3x + 5 = 4x - 11 {subtract 5 from both sides)
3x = 4x - 16 {subtract 4x from both sides)
-x = -16 {divide both sides by (-1)}
x=16
So:
RS = 2x + 15 = 2×16 + 15 = 32 + 15 = 47
5 out of 25
