19/42=9 The input is a contradiction it has no solutions.
0.04, or 4 hundredths is 10 percent of 0.40
10 times 0.04 gives you 0.40
What part do you have trouble with
It should be d. , Because if you take the equation 3x+y=9, and make it slope intercept form, it would be y= -3x+9. -3 is the slope, and 9 is the y intercept. D is the answer.
