Answer:
Step-by-step explanation:
hello :
√(5/4)= √5/ √4 =√5/2 = (1/2)√5
3+√5/4−√5 = 3+(1/2)√5 so : a=3 and b= 1/2
2.79 / 2 = 1.395 rounds to 1.40 per roll
8.99 / 6 = 1.498 rounds to 1.50 per roll
the better deal (cheapest) is the 2 roll package
** if u want price per roll (price / roll) ...u divide the price by the number of rolls
The point-slope form of the equation for a line is good for this. It tells you the line with slope m through point (h, k) has equation
... y -k = m(x -h)
For your point and slope, an equation of the line is
... y -1 = -5(x -9)
