Chase plays the piano and the cello. for every 2 hours he practices the piano, he practices the cello for 3 hours. if he practiced the piano for 6 hours last week, how many hours did he spend practicing the cello?

if Chase practices 3hr of cello per every 2hrs of piano, first find how may times does 2hrs goes into the total 6hrs:

6 ÷ 2 = 3

Then multiply the number the hours of cello by the total 2 hours of 6;

3 × 3 = 9

so your final answer would be:  9 hours of cello

4x and 6y

im not sure though

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
