Choose equation below that represents is the line passing through the point (1 , -4) with a slope of 1/2 a. y - 4 = 1/2(x - 1) b. y + 4 = 2(x - 1) c. y + 4 1/2 (x - 1) d. y - 4 = 2(x + 1)

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11

9 sandwiches per hour

step-by-step explanation:

when we have a rate, we want a 1 in the denominator

27/3 = 9

27 sandwiches/ 3 hours = 9 sandwiches/hour
