Answer:
area=56000 yards²
Step-by-step explanation:
first divide 280 by 7 and get 40
scale factor is 40
5x40=200
200x280=56000
area=56000 yards²
 
        
             
        
        
        
Slope of tangent line = dy/dx = 2x+3
k is y_intercept of tangent line
2x+3 = -1
x = -2
y = (-2)^2+3(-2)+1 = -1
tangent line passes through point (-2,-1)
k = x+y
k = -2 -1
k = -3
 
        
        
        
Answer:
Correct answer: B
Step-by-step explanation:
Syntax: in piecewise functions such as the one attached, the "if:" section shows the domain, or x-axis values which that function pertains to. 
In the graph, you can see that the graph is defined for  (not-including 1 because there is an open hole there, indicating it is not part of the domain), and
 (not-including 1 because there is an open hole there, indicating it is not part of the domain), and  .
. 
Now that we know the domain, we can attach it to the graphs that lie on those domains. 
We see that the leftmost line appears to have a positive slope and a negative y-intercept, and that the second line should have a positive y-intercept and a negative slope. 
At this point, you can just start crossing off answers that don't meet this criteria.
