1.2 Inches, It moves 0.3 inches in 1 hour so if in 1 hour it moves 0.3 and in 2 0.6 and in 3 0.9 so in 4 hours it will move 1.2 inches
Answer:
See below
Step-by-step explanation:
For the model function 
, 
is the vertex, and 
is the horizontal growth or shrink factor.
We know that our vertex is 
from our graph, so we'll need to determine the value of by using one of the points on the graph:
Thus, our equation for the given graph is 
.
The domain of a function is the set of all existing real x-values, thus, our domain for the given function is 
, or all real x-values.
The range of a function is the set of all existing real y-values, thus, our range for the given function is 
, or all real y-values starting with y=-1 which is included.
Answer:
5
Step-by-step explanation:
Subtract 1 from both sides. The equation becomes 2.5d + 6.25 = 3.75d
Subtract 2.5d from both sides. The equation becomes 6.25 = 1.25d
Divide 1.25 from both sides. You get 5 = d
Answer:
1. 1
2. 5
3. lost 0.8 pounds
Step-by-step explanation:
The least value (or the most she lost) is in week 1
The greatest value (or the most she gained) is in week 5
When you add all the values together, you get:
-4.1 (lost)
3.3 (gained)
3.3 - 4.1 = -0.8
She lost a total of 0.8 pounds
These are your answers

Answer:
B) The cost of milk by the gallon.
C) The price of pears by the pound.
Step-by-step explanation:
A linear function is one that both the dependent and independent variables increases or decreases proportionally.
Thus from the given options:
i. If the gallons of milk increase, then the cost of milk also would increase proportionally. A decrease in the gallons of milk would also reduce the cost of milk.
ii. An increase in the pounds of the pearls would cause an increase in the price of the pearls. Also, a decrease in the pounds of pearls would reduce the price of the pearls.
Thus, the answers to the question are options B and C.
