Answer:
The average per cost is $19.25.
Step-by-step explanation:
Given:
The fee paid by cat owner = $269.50. Total visits he made that year 14.
Now, to find the average per cost.
So, to get the average per cost we divide the total fee by total visits:
Average per cost = Total fee ÷ Total visits
= ![269.50\div 14](https://tex.z-dn.net/?f=269.50%5Cdiv%2014)
= ![19.25](https://tex.z-dn.net/?f=19.25)
Therefore, average per cost is $19.25.
Answer:
A
Step-by-step explanation:
I hope this helps
x = - 1
given
= x + 3
square both sides
1 - 3x = (x + 3 )² ( expand right side using FOIL )
1 - 3x = x² + 6x + 9 ( subtract 1 - 3x from both sides )
0 = x² + 9x + 8
0 = ( x + 1)(x + 8)
equate each factor to zero and solve for x
x + 1 = 0 ⇒ x = -1
x + 8 = 0 ⇒ x = - 8
As a check
substitute these values into the equation and if both sides are equal then they are the solutions
x = - 1 :
= 2 and - 1 + 3 = 2 ← true
x = - 8 :
= 5 and - 8 + 3 = -5 ← false
thus the only solution is x = - 1
Answer:2
Step-by-step explanation :put both of your finger up
