2x^2-2x+9=0
(2x-1)(2x-1) = 0
x = 1/2
Answer:
alternativa d) Alternate Interior Angles
Answer:
1.875
Step-by-step explanation:
the average rate of change of g(x) in the closed interval [ a, b ] is
here [a, b ] = [- 1, 3 ] , then
g(b) = g(3) = 2³ + 1 = 8 + 1 = 9
g(a) = g(- 1) = 
+ 1 = 
+ 1 = 1.5
then
average rate of change = 
= 
= 1.875
Let me know if you need me to explain!
The total amount that Chang will received from his wages is the product of his hourly wage times the number of hours he has worked (n). His total savings should not be less than $125. The equation that best describes the situation is,
45 + 7n ≥ 125
Solving for n in the inequality gives an answer of n≥11.42 hours. Thus, he needs to work for at least 12 hours.
