The answer is that the first one is not the longer one the second one is.
the first one equals 2
the second one equals 5
Answer:
3= A
2=A or D I am not sure
Step-by-step explanation:
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
Since real numbers are closed with respect to division (i.e. the division between two real numbers is again a real number), the fraction 
is a real number everytime both m and n are real numbers.
In other words, you can choose any real number m and any real number n, and their ratio will still be a real number.
Of course, you have to follow the only rule that you can't divide by zero, so the answer is more precisely
Answer:
110°
Step-by-step explanation:
5x+10=4x+19
5x-4x =19-10
x = 9
m <em>L</em><em> </em>ADB = 5(9)+10=45+10=55°
so m <em>L</em><em> </em>ADC = 2×55° = 110°
