Answer:
A (no because the graph is not a straight line)
Step-by-step explanation:
The rate of change is not consistent, and therefor is not proportional.
What are you solving for?
If you are solving for × then I hope this helps
Let's solve for x.
f(x)= 100−10+e−0.1x
Step 1: Add 0.1x to both sides.
xf+0.1x=−0.1x+e+90+0.1x
xf+0.1x = e+90
Step 2: Factor out variable x.
x(f+0.1) = e+90
Step 3: Divide both sides by f+0.1.
x(f+0.1)/ f+0.1 =e+90/ f+0.1
x=e+90/ f+0.1
Answer:
x= e+90/ f+0.1
11 = -d+15
subtract 15 from each side
-4 = -d
divide both sides by -1
d = 4
