The percentage error is 23%
Explanation:
The estimated total cost of the groceries = $50
The actual cost of the groceries = $65
To find the error value, we need to subtract the value of actual cost and total cost of the groceries.
Thus,
error value = actual cost - total cost
error value 
Hence, error value = $15
The formula to determine the percent error is given by

Substituting the values in the formula, we get,

Rounding off the value, we have, 23%
Thus, the percentage error is 23%

Rewrite in vertex form then use this to find the vertex (opposite of h , K)
Answer:
b=4
Step-by-step explanation:
4b+5=1+5b (subtract 4b on both sides to get the b's together)
-4b -4b
5=1+5b-4b (subtract 1 from both sides)
-1 -1
4=1b (divide by 1)
b=4
