Algebra 1 what is the solution to the system? 7x+5y=19 -7-2y=-16 a: (2,1) b: (1,2) c: (7,5) d: (-7,-2)

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

What are the domain and range of the function f(x)=2^x+1

Here is another math questions. i will keep asking different questions. 4^2x=6
