Answer:
(x - 
)² + 
Step-by-step explanation:
x² - 5x + 8
Using the method of completing the square
add/subtract ( half the coefficient of the x- term )² to x² - 5x
x² + 2(- )x + 
- + 8
= (x - )² - + 
= (x - )² +
Answer:
251.2
I used 3.14 as pi
Step by step explanation:
SA= 2(pi*r²) + (pi*d)h
SA= 2 (
* 4² ) + (pi*8)*6
<u>you could also do this:</u>
SA=2πrh + 2πr²
B. Barbara's equation did not consider the number of bottles of iced tea. She only put 1.49, which would mean she only sold one. Because we know she sells more then one, it should be 1.49(then a variable)

Answer:
x-intercept: -14/9
y-intercept: 7
Step-by-step explanation:
This is one of the easiest forms for finding intercepts. To find the x-intercept, set y=0 and divide both sides by the coefficient of x.
-9x = 14 . . . . . set y=0
x = -14/9 . . . . divide by -9
__
To find the y-intercept, set x=0 and divide both sides by the coefficient of y.
2y = 14 . . . . set x=0
y = 7 . . . . . . divide by 2
The x-intercept is -14/9; the y-intercept is 7.
