Answer: 7 Answers Incorrect
Step-by-step explanation:
86% may be written as (86/100) or as 0.86.
Since "it's a ratio (sic.) problem," then:
86/100 = correct/50
correct = (86/100)*50 (multiply both sides by 50)
correct = 43
And, 50-43 = 7 incorrect
Answer:
-8/5
Step-by-step explanation:

Answer (-3,6)
#
f(x)=x ² +6x+15
=(x ² +6x+9)+6
=(x+3) ²+6
the vertex:(-3,6)
(-3, 1.5)....simply add the x coordinates together, divide them by two, and then do the same for the y coordinates.
