Answer: 1; 2; 3; 6; 23; 46; 69 and 138.
Step-by-step explanation:
276 and 138 have 8 common factors (divisors), out of which 3 prime factors, 2; 3 and 23:
1; 2; 3; 6; 23; 46; 69 and 138.
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
1.2 + d + 0.4 = 9.7
1.6 + d = 9.7
1.6 (-1.6) + d = 9.7 (-1.6)
d = 8.1
your answer is 8.1
hope this helps
