Two objects are moving along separate linear paths where each path is described by postion, d, and time, t. the variable d is measured in meters and the variable t is measured in seconds. the equation describing the graph of the postion of the first object with respect to time is d=2.5t+2.2. the graph of the the position of the second object is a parallel line passing through (t=0,d=1). what is the equation of the second graph.

d=2.5t+1
d=-0.4t+1
d=2.5t+3.2

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

According to a study conducted in 2015, 18% of shoppers said that they prefer to buy generic instead of name-brand products. suppose that in a recent sample of 1500 shoppers, 315 stated that they prefer to buy generic instead of name-brand products. at a 5% significance level, can you conclude that the proportion of all shoppers who currently prefer to buy generic instead of name-brand products is higher than .18? use both the p-value and the critical-value approaches.
