A special calculator contains a red key. When the red key is pressed, the number on the screen will be added by its unit digit. For instance, if the screen shows 27 and the red key is pressed, the number on screen becomes 27 + 7 = 34, if the red key is pressed again the number on screen becomes 34 + 4 = 38, and so on. A positive integer is now input to the calculator. The red button is then pressed some number of times, and the integer on the screen becomes 1234. What is the smallest possible value of the integer input?

What is the point-slope equation of a line with slope -5 that contains the point (6,3)

Hich equation can pair with x + 2y = 5 to create an inconsistent system? 2x + 4y = 3 5x + 2y = 3 6x + 12y = 30 3x + 4y = 8

Ascientist studied a population of workers to determine whether verbal praise and/or tangible rewards affect employee productivity. in the study, some workers were offered verbal praise, some were offered tangible rewards (gift cards, presents, and some were offered neither. the productivity of each participant was measured throughout the study by recording the number of daily tasks completed by each employee. which inference might the scientists make based on the given information? a.) the number of daily tasks completed by each employee may influence the dependent variable, which is whether the employee receives verbal praise, tangible rewards, or neither. b.) verbal praise and/or tangible rewards may influence the independent variable, which is the number of daily tasks completed by each employee. c.) verbal praise and/or tangible rewards may influence the dependent variable, which is the number of daily tasks completed by each employee. d.) the dependent variables, which are verbal praise and tangible rewards, may influence the number of daily tasks completed by each employee.
