Answer:
GCF is 9
Step-by-step explanation:
Factor out 9 and divide what's in the parentheses by 9
9(7+5b)
Answer: (13 + y) / 5
Step-by-step explanation:
Since Grandma Gertrude gave 13 pieces of jewelry and Grandma Fien gave y pieces of jewelry to the Carlson sisters, the total jewellery given to the sisters will be:
= 13 + y
Since there are 5 Carlson sisters, the number of pieces of jewelry that each sister receive will be:
= Total jewelries / Number of sisters
= (13 + y) / 5

We can see the slope of f is -3, because for every one unit to the right, the graph goes down three units. We can check this from two points, say (0,2) and (1,-1).
m = (-1 - 2)/(1 - 0) = -3
g is in slope-intercept form so we read off the slope of g as n=-5
Of course -3 > -5
Answer: B, slope of f is greater
