Point D D is located at ( 2 , − 6 ) (2,−6) on the coordinate plane. Point D D is reflected over the y y-axis to create point D ′ D ′ . Point D ′ D ′ is then reflected over the x x-axis to create point D ′ ′ D ′′ . What ordered pair describes the location of D ′ ′ ? D ′′ ?

The function a represents the cost of manufacturing product a, in hundreds of dollars, and the function b represents the cost of manufacturing product b, in hundreds of dollars. a(t) = 5t + 2 b(t) = 7t - 2t +4 find the expression that describes the total cost of manufacturing both products, a(t) + b(t). a. 7t^2 - 7t + 2 b. 7t^2 + 3 +6 c. 7t^2 + 7t - 6 d. 7t^2 - 3t + 6

True or false look at the picture pls : /

Given: m∠ adb = m∠cdb ad ≅ dc prove: m∠ bac = m∠bca lol
