Hello :
y= <span>x² - 4x + 1
calculate : x
y = (x²-4x+4)-4+1
y+3 = (x-2)²
x exist : if y+3 </span><span>≥ 0
y </span><span>≥ -3
the range is : </span><span>{y: y ≥ -3}</span>
Answer:

Step-by-step explanation:
Given:
Slope (m) = -2
Point on the line = (4, -6)
Required:
Point-slope equation of the line
Solution:
Point-slope equation takes the following form:
,
Where,
m = slope of the line = -2
(a, b) = coordinates of the point on the line. = (4, -6)
Plug in the values into the slope-point equation


Answer:
you want to "isolate" the variable "p" sooo...
Step-by-step explanation:
add 17 to both sides of the equation.... so you get
p = -6 :)
200=10x divide by 10 and get 20=x. they make 20 quarts of ice cream every hour. multiply by 12, we get 240=12x. they can maek 240 quarts in 12 hours
