A cereal manufacturer has a tolerance of .75 oz for a box of cereal that is supposed to weigh
20 oz. Write and solve an absolute value
inequality that describes the acceptable weights
for a 20 oz box.

let the absolute weight of the box of cereal be X

20-0.75 ≤ x ≤ 20+0.75

19.25 ≤ x ≤ 20.75

60

step-by-step explanation:

b

step-by-step explanation:

the equation of a line in point- slope form is

y - b = m(x - a)

where m is the slope and (a, b) a point on the line

calculate m using the slope formula

m = (y₂ - y₁ ) / (x₂ - x₁ )

with (x₁, y₁ ) = (0, 4) and (x₂, y₂ ) = (3, - 5) ← 2 points on the line

m = = = - 3

with m = - 3 and (a, b) = (3, - 5), then

y - (- 5) = - 3(x - 3), that is

y + 5 = - 3(x - 3) → b
