Answer:
Y = -24
Step-by-step explanation:
For this problem, evaluate simply means for each x, replace the value with -2. So, let's do that.
Y = 6*2x
Y = 6*2(-2)
Y = 6*-4
Y= -24

8.49 x 10⁻⁷ = 0.000000849
Answer: x = -1
Step-by-step explanation:
You need to convert to the same base

So

For these values to be equal, the exponents have to be equal
-4 = -2x - 6
2 = -2x
x = -1
B, (0,3)
If you plot each point this is the only one that touches the line.
The average rate of change is calculated as the slope of the line between the two points on the graph. Since at x = 1, y = -3, and at x = 3, y = 1, these are the two points which we calculate the slope from. Using the formula
m = (y2 - y1)/(x2 - x1)
m = (1 - (-3))/(3 - 1)
m = 4/2
m = 2
Therefore the slope, or the average rate of change, between these points is 2.
