Answer:
The equation of the graph after translating one unit to the left is;

Step-by-step explanation:
The given equation is 
We note that minimum value of y = 3, where 1/2·x - 2 = 0 and x = 4
Therefore, in moving one unit to the left, we have at the y-intercept where slope of the graph has become inverted (reflection of the real graph) we add one to the x value as follows;

The equation of the graph becomes;
.
Answer:
It is larger by
times
Step-by-step explanation:
You use exponential division for this problem
first, divide 8 by 2
8/2 = 4
Then, look at 10^9 and 10^7
The bases of those numbers are the same, so you can just subtract the exponents since you're dividing.

Combine those two together to get:
4 * 10^2
answer:
Step-by-step explanation:
DE/2 = 30.5
CE=30.5
DC=30.5
3x + 5 = 30.5
3x = 30.5 - 5
3x = 25.5
25.5/3 =8.5
x=8.5
