Step-by-step explanation:
-7/6 it is the slope of this line
You use the equation A=P(1+rt) and sub in the numbers.
Ratios can be written as fractions.....so the ratio of black keys to white keys is 6:8...which can be written as 6/8....which reduces to 3/4...hence the ratio simplified is 3:4......which is also written as 3/4 and as 3 to 4
Answer:
the new coordinates would be B´(1,0), C´(1,7), D´(-3,-3)
Step-by-step explanation:
you do this by taking each number and adding by the scale factor of 2!! hope this helps
