Solve the system by substitution.
x = – 4y + 6
2x + 9y = 16

Asap for seven months an ice creams vendor collects data showing the number of cones sold a day (c) and the degrees above 70 degrees f the vendor finds that there is a positive linear association between c and t that is the best modeled by this equation c=3.7t+98 which statement is true? the model predicts that the average number of cones sold in a day is 3.7 the model predicts that the average number of cones sold i a day is 98 a model predicts that for each additional degree that the high temperature is above 70 degres f the total of number of cones sold increases by 3.7 the model predicts for each additional degree that the high temperature is above 70 degrees f the total number of cones sold increasingly by 98

Find the value of x in each case. give reasons to justify your solutions! d q ∈ pr

y=2x−1 5x−4y=1 is (1,1)(1,1) a solution of the system?
