Answer:
The answer to your question is:
Step-by-step explanation:
12.-
x² - 6x = 5
x² - 6x + (3)² = 5 + (3)²
x² - 6x + 9 = 5 + 9
(x - 3)² = 14
13.- x² - 6x = 12
x² - 6x + (3)² = 12 + (3)²
x² - 6x + 9 = 12 + 9
(x - 3)² = 21
x - 3 = ±√21
x1 = √21 + 3 x2 = -√21 + 3
x1 = 7.58 x2 = -1.58
14.- 2x² - 24x = - 20 Divide by 2
x² - 12 x = -10
x² - 12x + (6)² = - 10 + (6)²
x² - 12x + 36 = - 10 + 36
( x - 6) ² = 26
x - 6 = ±√26
x1 = √26 + 6 x2 = -√26 + 6
x1 = 11.1 x2 = 0.9
Answer:
Company C!
Step-by-step explanation:
In order to see which company has the best buy we have to see the amount each company sells for one stuffed mascot. In order to do this we have to divide .
Company A:
Company A sells 16 lions for $44.32 this is the same as 1 stuffed lion for $2.77.
Company B:
Company B sells 18 lions for $50.22 this is the same as 1 stuffed lion for $2.79.
Company C:
Company C sells 12 lions for $32.88 this is the same as 1 stuffed lion for $2.74
Thus as you can see the company with the best buy is company C.
So percent is parts out of 100 so x%=x/100
68/70
divide totaly
0.9714/1
multiply by 100/100 to make bottom 100
97.1% is the answer
Collecting like terms,
Since the signs change when its position changes.
The axis of symmetry is 2 and the vertex is (2, 4).
