THIS IS SO BAD RN SMH HELP ME WITH ANOTHER MATH SOLVING
4 x 3 x 4 x 9 + 3 - 20

The graph shows the decibel measure for sounds depending on how many times as intense they are as the threshold of sound. noise in a quiet room is 500 times as intense as the threshold of sound. what is the decibel measurement for the quiet room? 20 decibels28 decibels200 decibels280 decibels

Which equation represents a line that passes through the point (9, -4) and has a slope of 3/5?

The function below is written in vertex form or intercept form. rewrite them in standard form and show your work. y = 5(x+3)^2-4
