Answer:
Exponential equations
Step-by-step explanation:
Marcy bought a total of 22.8 potatoes. 10.32+12.48=22.8
Answer:
The car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Step-by-step explanation:
Let be
, where
is the stopping distance measured in metres and
is the speed measured in kilometres per hour. The second-order polynomial is drawn with the help of a graphing tool and whose outcome is presented below as attachment.
The procedure to find the speed related to the given stopping distance is described below:
1) Construct the graph of
.
2) Add the function
.
3) The point of intersection between both curves contains the speed related to given stopping distance.
In consequence, the car must have a speed of 25 kilometres per hour to stop after moving 7 metres.
Answer: A. c = 3d
I'm gonna go with c = 3d
Step-by-step explanation: c = 3d
After looking at the table I believe the equation would be c=3d. I came to this conclusion because (6)=3(2); (9)=3(3); (15)=3(5); 18=3(6). I really hope this helps!:)

Answer:
Step-by-step explanation:
Days Cost
2 6
3 9
5 15
6 18
Now to find equation that models the given data we will use two point slope form.
Formula:
Substitute the values in the formula
where y denotes the number of days and x denotes the cost
Let us suppose d denotes the number of days and c denotes the cost
So, equation becomes:
Hence an equation models the data in the table is
So, option A is true.
X - tickets
----------------------------------
167x + 19x + 16 = 1132
186x + 16 = 1132
186x = 1132 - 16
186x = 1116
x = 1116 : 186
x = 6 tickets (answer).
