Answer is -3</h3>
How I got that answer:
The graph shows the two points (0,-4) and (-2,2) are on the parabola. The x coordinates of both points are from x = 0 and x = -2 as given in the instructions. Compute the slope of the line through those points. The slope of this line is the exact same as the average rate of change from x = -2 to x = 0.
m = (y2 - y1)/(x2 - x1)
m = (2 - (-4))/(-2-0)
m = (2 + 4)/(-2-0)
m = 6/(-2)
m = -3
A negative slope means the line slopes downhill as you move from left to right. This is a negative average rate of change.
Answer:
x = 4 or x = -10 for equation x^2 + 6x = 40
Step-by-step explanation:
x^2 + 6 = 40
x^2 = 40 - 6
x^2 = 34
x = root(34) or x = -root(34) but this is not in the answer choice.
is it x^2 + 6x = 40
x^2 + 6x + 9 = 40 +9
(x + 3)^2 = 49
x + 3 = 7 or x + 3 = -7
x = 4 or x = -10
Answer:
first 2 and the 2nd to last one
Step-by-step explanation:
Answer: 2/5 ÷ 2 = 2/10 as simplified as 1/5 in fraction form. 2/5 ÷ 2 = 0.2 in decimal form.
