Answer:

Step-by-step explanation:
1.500 since 45 rounds to 50
Answer:

Step-by-step explanation:
1) The Point-slope form equation is given in this form:

2)Looking at the given graph, we can pick two points: (-5,-4) and (0,-3)
3) Before using the Point-slope form We have to find out the slope:

4)Parallel lines share the same slope. The one that passes through (-2,2) is found by calculating its linear parameter "b":

Then, the answer is:

Answer:
Option D. minimum value at −38
Step-by-step explanation:
we have

Let

Complete the square




------> equation of a vertical parabola in vertex form
The vertex is the point 
The parabola open upward-----> the vertex is a minimum
therefore
minimum value at −38
