Hello! A stone has mass 80 g. When it is submerged in water in a measuring cylinder, the level rises from 120 cm to 160 cm.

a. What is the volume of the stone?
b. What is its density?

14. (05.02 lc) what is the value of y in the solution to the following system of equations? (5 points) 2x + y = −4 5x + 3y = −6

Rewrite the following quadratic functions in intercept or factored form. show your work. f(x) = 3x^2 - 12

What is the distance between a and b? round your answer to the nearest tenth. a coordinate plane is shown. point a is located at negative 1, 5, and point b is located at 4, 1. a line segment connects the two points.
