Q. Determine the value of y, if x is −9 .y=∣x∣+10Answer:
Substitute x in equation: Substitute the value of x into the equation.We are given the equation y=∣x∣+10 and we need to find the value of y when x is −9.Substitute −9 for x in the equation.y=∣−9∣+10
Evaluate absolute value: Evaluate the absolute value of x. The absolute value of −9 is 9 because absolute value measures the distance from zero without considering direction. y=9+10
Add numbers to find y: Add the numbers to find the value of y.Now we just need to add 9 and 10 together to find y.y=19
