Afactory makes sheets of metal that are 2 1/4 inches think. if a worker makes a stack of 5 sheets, how many inches thick will the stack be?

firstly you convert 2 1/4 which is 9/4 and you times that by 5 like

9/4 times 5/1 = 45/5 which converts to 9

the answer is 9 inches high

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
