Solve the application by using a system of linear inequalities in two variables.A bakery plans to market a mixed assortment of its two most popular cookies: Chocolate Chip and Toffee Chunk. Their marketing analyst proposes that the new assortment be constrained by the inequality src="https://sciemce.com/media/4/ppg__10708191732__f1q37g3.jpg" alt="" style="vertical-align: -4.0px;" /> and 
where C is the number of Chocolate Chip cookies and T is the number of Toffee Chunk cookies. Their sales analyst suggests in order to offer a reasonably priced product the assortment should be constrained by the inequality 
The number of each type of cookie cannot be negative, so 
Graph the region satisfying all the requirements for the assortment using C as the horizontal axis and T as the vertical axis. Does the combination of 1 Chocolate Chip cookies and 7 Toffee Chunk cookies satisfy all of the requirements? 
A.
; Yes
B. 
; No
C. 
; No
D. 
; Yes
Verify the identity.sin(? - ?) cos(? + ?) = sin ? cos ? - sin ? cos ?
What will be an ideal response?
