1) x^2 + 8x + 16 = (x+4)^2
Answer: C. 16
2) x^2 + 4x + 4 = (x+2)^2
Answer: B. 4
Answer:
C
Step-by-step explanation:
A is for sure wrong because we can see the distribution of the data showing us that the center is at 8. B is also wrong because the spread is only from 6.5 even though the table goes from 5. C would be correct because its symmetrical in shape.

Answer:
Step-by-step explanation:
Let the equation of the line passing through a point (x', y') and slope 'm' is,
y - y' = m(x - x')
Since x-value increases by 3,
Δx = 3
And y-value decreases by 2,
Δy = -2
Therefore, slope = 
Slope = 
Equation of the line passing through (-2, 5) and slope =
will be,
y - 5 = 
y = 
y = 
y = 
Table for input-output values will be,
x -2 0 1 2 3
y 5 3.7 3 2.3 1.7
We can plot these points to get the line on a graph.
