The rule below shows how mr. perez's long-distance phone company computes his monthly bill. which answer expresses that rule in the form of an equation?
multiply the number of minutes mr. perez spent on long-distance calls by $0.45, the long-distance rate. then add $33, the flat monthly charge.
a. f(t) = $(0.45 t 33)
b. f(t) = $t (0.45 33)
c. f(t) = $0.45 t 33
d. f(t) = $0.45 (t 33)

Mr. walker gave his class the function f(x) = (x + 3)(x + 5). four students made a claim about the function. each student’s claim is below. jeremiah: the y-intercept is at (15, 0). lindsay: the x-intercepts are at (–3, 0) and (5, 0). stephen: the vertex is at (–4, –1). alexis: the midpoint between the x-intercepts is at (4, 0). which student’s claim about the function is correct?

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
