Step-by-step explanation:

Bobby's uncle gave him 300 baseball cards. Each week, Bobby purchases 40 baseball cards to add to his collection.

Let the number of weeks he collects cards be w.

The inequality to get the number of weeks after starting his collection when Bobby will have more than 700 baseball cards in his collection is given by:

If you want to find w;

=>

w > 10

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
