Answer:

Step-by-step explanation:

To determine which point is a solution, substitute the x- coordinate into the equation and if the value obtained agrees with the y- coordinate of the point then it is a solution.

A (- 3, - 17)

y = 4(- 3) - 5 = - 12 - 5 = - 17 ← (- 3, - 17) is a solution

B (4, 7)

y = 4(4) - 5 = 16 - 5 = 11 ≠ 7 ← not a solution

C (- 2, - 18)

y = 4(- 2) - 5 = - 8 - 5 = - 13 ≠ - 18 ← not a solution

D (3, 17)

y = 4(3) - 5 = 12 - 5 = 7 ≠ 17 ← not a solution

A cubic box is completely filled with 2,179 g of water. What is the length of one side of the box, in meters? m Explain your rea

Mazyrski [523]

Answer:

$l\approx 1.296\,cm$

Step-by-step explanation:

The water density is approximately 1 gram per cubic centimeter, which means that 1 gram of water occupies a volume of a cubic centimeter. Hence, 2.179 grams occupies a volume of 2.179 cubic centimeters.

Let assume volume occupied by the water has a cube-like shape, whose side has the following measure:

$l = \sqrt[3]{2.179\,m^{3}}$
