Karin is also in mr. whittaker’s science class, and she recorded the variation in water level at a different part of the river. karin observed that the water level there fell 1.68 millimeters per year for 1.5 years. which expression shows a way to use the distributive property to solve for the total variation in water level at this part of the river?
a) 1.5(-1) + 0.68
b) 1 + (0.)(0.68)
c) (-1.68)(1) + (-1.68)(0.5)
d) 1(-1) + 0.5(-0.68)

The correct answer option is c) (-1.68)(1) + (-1.68)(0.5).

Step-by-step explanation:

Fell in water level per year = -1.68 millimeters

Fell in level of water in 1.5 years = -1.68 × 1.5

Showing this expression according to the distributive property:

So the expression (-1.68)(1).+(-1.68)(0.5) shows a way to use the distributive property to solve for the total variation in water level at this part of the river

f(x) is the value of the function. b is the value of the function when x equals zero or the y-coordinate of the point where the line crosses the y-axis in the coordinate plane.
