Answer:
x=4
Step-by-step explanation:
2x=4x-8
2x-4x=-8
-2x=-8
x=4
8.11 as an improper fraction is 811 over 100 811/100 if you convert
Answer:
The minimum value = -38
Step-by-step explanation:
∵ f(x) = x² - 12x - 2
∵ -12x ÷ 2 = -6x ⇒ -6 × x
∴ (x - 6)² = x² - 12x + 36
∴ Add and subtract 36 in f(x)
∴ f(x) = (x² - 12x + 36) - 36 - 2
∴ f(x) = (x - 6)² - 38 ⇒ completing square
∴ The vertex of the parabola is (6 , -38)
∵ Its minimum point because the coefficient of x² is positive
∴ The minimum value = -38
Answer:
WITH DECIMAL: the bigger the demominateor (the bottom number) is, the smaller the value of the number. for ex. 1/4 is smaller then 1/2, 1/8 is bigger then 1/16, etc.
1/4 would go in between 0 and -1 because 1/4 isn't a whole number
-3 1/4 would go in between -3 and -4 becauce 3 AND 1/2 is more then just a 3
-2 3/4 would go in between -2 and -3 becasue 2 + other 3/4 is going to be bigger than 2 but smaller than a 3
9/4 is a tricky one casue 9 is bigger then 4. so you need to see how many times 4 goes into 9 (2 times = 4 +4 = 8) so the simplfied version would be 2 1/4 casue 9 - 8 = 1. so the 9/4 would go in between 2 and 3
lastly, the 3/4 would go in between 0 and 1 becasue 3/4 is deffinately smaller than 1 and definatly bigger than 0
