Answer:
Plumber A
Step-by-step explanation:
Given the following :
Hours ___repair cost
________A ____B____C_____D
1 ______$35___55___50____50
2 _____ $65__ $75__ $75__ $60
3 _____ $95__ $95 _$100 ___$70
Charge plan:
Flat fee(x) + hourly rate(y)
For 1 hour:
Plumber A:
x + y = 35 ; x = 35 - y
x + 2y = 65 ;
35 - y + 2y = 65
y = 65 - 35 = $30 hourly
Plumber B:
x + y = 55 ; x = 55 - y
x + 2y = 75 ;
55 - y + 2y = 65
y = 65 - 55 = $10 hourly
Plumber C:
x + y = 50 ; x = 50 - y
x + 2y = 75 ;
50 - y + 2y = 65
y = 65 - 50 = $15 hourly
Plumber D:
x + y = 50 ; x = 50 - y
x + 2y = 60 ;
50 - y + 2y = 60
y = 65 - 50 = 10 hourly
Hence, Plumber A charges the highest hourly rate at $30 per hour
Answer:
Step-by-step explanation:
It's the vertex form of a quadratic equation of
The vertex is at (h, k).
k is minimum or maximum for value of h.
k - its value of y for x = h.
We have
[tex]k=2(8^2)-32(8)+56=2(64)-256+56=128-256+56=-72[/tex
The answer is A because all the angles in a triangle add up to 180 degrees
answer: 4
explanation: it would be 4 because slope is rise/run and it rises 4 and runs one so u would get 4/1 which is 4 simplified. :)
