The graph shows the membership of a student group: x represents the number of years since the group was formed and y represents the number of members.
A graph has years since group formed on the x-axis, and number of members on the y-axis. A line goes through points (2, 38) and (5, 80).
The equation is y = 14x + 10.

Which is true regarding the slope?
A. Membership grows by 14 each year.
B. The group was formed with 14 members.
C. Membership is recorded every 14 years

1. are the triangles similar and if so why? what is the value of x? show your work.

Could someone with number 1 and 2

Someone answer asap for ! a discount store’s prices are 25% lower than department store prices. the function c(x) = 0.75x can be used to determine the cost c, in dollars, of an item, where x is the department store price, in dollars. if the item has not sold in one month, the discount store takes an additional 20% off the discounted price and an additional $5 off the total purchase. the function d(y) = 0.80y - 5 can be used to find d, the cost, in dollars, of an item that has not been sold for a month, where y is the discount store price, in dollars. create a function d(c(x)) that represents the final price of an item when a costumer buys an item that has been in the discount store for a month. d(c(x)) =
