In a village the cases of a particular infectious disease have been exponentially decreasing at a rate of 90% per year since the people started recieving the vaccine. If there were 100 cases to start with. Predict the number of cases after 2 years.

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula, equation, to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

Through: (-3,-3) parallel to y= 7/3x+3

Jacob signs up to work for 2 1/2 hours at the school carnival. if each work shift is 3/4 hour, how many shifts will jacob work? (i just want to double check : |, for anybody that responds! : )
