For this case we have the following equation:
y = x2-4x + 3
Deriving we have the following equation:
y '= 2x-4
We equal zero and clear x:
2x-4 = 0
x = 4/2
x = 2
Substituting in the given equation we have:
y = (2) ^ 2-4 (2) +3
y = 4-8 + 3
y = -1
The vertex will be the ordered pair:
(x, y) = (2, -1)
Answer:
(x, y) = (2, -1)
option B
X = rate of mechanic who worked 5 hours
y = rate of mechanic who worked 15 hours
x + y = 200
5x + 15y = 1950
you find the first variable in one of the equations, then subsitute the result into the other equation. your answer would be:
the mechanic who worked for 5 hours charged $105 per hour, the one who worked 15 hours charged $95 per hour.
hope this helps :)
A = x > -3 and x < 4
B = x >withlineunder -3 and x <withlineunder 4
C = X < - 3 or X > 4
Your answer is c, because 69,000 is less than 96,000. I hope this helped! Could I possibly get brainliest?
Answer:
it would be 10/5 or 2
Step-by-step explanation:
y2-y1/x2-x1
17-7/9-4
10/5 simplify
2
