Answer:
-3 7/2
Step-by-step explanation:
the reciperacol of -3 2/7 is just the inverse opposite of that number. i think
FIRST. find the factors:
X=-5 --> (X + 5) = 0
x = 1--> (X - 1) = 0
x =3 --> (x - 3) = 0
3
NEXT, multiply all the factors:
(x + 5) (x - 1) (x - 3) = 0
-> X3 + x2 - 17x +15 = 0
-> f(x) = x3 + x2 - 17x +15 or
y=x3 + x2
17x + 15
C. Plumber A and Plumber B will both charge $135 if they each work 2.5 h.
Answer:
Amy
Step-by-step explanation:
Find their amounts of cheese per serving by dividing the cups of cheese by the number of people:
Sarah:
2.5/10
= 0.25
Amy:
1.6/8
= 0.8
Since 0.8 is bigger than 0.25, Amy has more cheese per serving.
