Answer:
84 in^2
Step-by-step explanation:
Find the area by first finding the average of 10 and 14 (it is 12) and then multiplying this result (12) by 6: area of trapezoid = 84 in^2.
Answer:
-43
Step-by-step explanation:
1. -3 x -3 x -3 = -27
2. -27- 4 x 4
3. -27- 16 = -43
Answer:
hope this helps
Step-by-step explanation:
five more: 5 +
three times the number q: 3q
Now put it together
Isolate the K by subtracting 19 from both sides
(19-19)-k=(4-19)
-k=-15
Get rid of the negative by dividing
-k/-1=-15/-1
k=15

Average rate of change is just the slope between the 2 points
we can do this the long way or the smart way
long way, find the 2 points and find the slope between them
when x=-5, f(-5)=-2(-5)+1=10+1=11
when x=1, f(1)=-2(1)+1=-2+1=-1
so the points are (-5,11) and (1,-1)
the slope between them is (-1-11)/(1-(-5))=(-12)/(1+5)=-12/6=-2
the answer is B, -2
smart way
recognize that that is a linear equation and the slope between any 2 points will be the m in y=mx+b
f(x)=-2x+1
the slope is -2
the average rate of change is -2
answer is B. -2
