The price of Stock A at 9 A. M. was $15.67. Since then, the price has been increasing at the rate of $0.12 each hour. At noon the price of Stock B was $16.17.It begins to decrease at the rate of $0.15 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?

-16.666666666 or -16 2/3

Step-by-step explanation:

0.12x + 15.67 = 0.15x + 16.17

0.03x = -0.5

x = -16 2/3

step-by-step explanation:

subtract 7, so the answer is x < = 3, or c.

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
