For this case we have the following equation:
Where,
n: number of invitations:
c: cost in dollars
We note that the slope of the line for this case is:
The slope represents the cost of printing each of the invitations.
Therefore, it is false that the cost of printing each invitation is $ 5.50
Answer:
the following is not true:
A) each invitation costs $ 5.50 to print.
I hope this helped you! Good luck!
(x+8) - 13 is the answer using x as “number”
Answer:
x = 65
Step-by-step explanation:
using the Altitude- on- Hypotenuse theorem
(leg of big Δ )² = (part of hypotenuse below it ) × (whole hypotenuse)
x² = 25 × 169 = 4225 ( take square root of both sides )
x =
= 65
Answer:
x = 10
Step-by-step explanation: 10/2 = 5 + 1 = 6
Answer:
<h2>B. The amount of fuel used was lowest at speeds around 60km/h.</h2>
Step-by-step explanation:
The decreasing part is from (20,13) to (60,6), which gives an average rate of

Then, we have an increasing part from (60,6) to (120,10), which gives an average rate of

Basically, at 60 km/h the fuel used was 6 liters per 100 kilometers. Notice that the other velocities make the car to use more liters per kilometers.
Therefore, the amount of fuel used was lowest at speeds around 60 km/h.
