Step-by-step explanation:
Step one:
given data
initial count of fish= 850
final count of fish= 500
Required
% decrease
Step two:
% decrease= final-initial/initial*100
substitute
% decrease= 850-500/850*100
% decrease=350/850*100
% decrease= 0.41*100
% decrease= 40.1%
<em>The percent decrease is approximately 40%. </em>

Answer:
28
Step-by-step explanation:
Using the rule of radicals
× 
⇔ 
= 
= 
×
= 4
Then
7
= 7 × 4
= 28
(X1=1, y1=7) and (x2= -4, y2 =-8)
Slope = ( y2-y1)/(x2-x1)= (-8-7)/(-4-1)= -15/-5=3
Slope is 3
