Match each example with the appropriate stage of technological design. 1. Evaluate the solution 2. Design a solution 3. Identify a problem or need 4. Implement the solution - a. Aerospace engineers need a lightweight material to build a jet. b. Engineers determine which features the material must-have. c. Engineers test a carbon-plastic compound in a wind tunnel. d. The carbon-plastic compound is redesigned to save maximum energy.

1.) a

2.) d

3.) b

4.) c

Explanation:

 1.) Evaluate the solution is like defining what you want to do or achieve. This matches with a. That is aerospace engineers need a lightweight material to build a jet. 

2.) Design a solution. That is, implementing what you want to achieve. This matches with d.The carbon-plastic compound is redesigned to save maximum energy.

3.) Identify a problem or need encountered matches with b. Engineers determine which features the material must-have

4.) By implementing the solution, the engineers test a carbon-plastic compound in a wind tunnel

b

explanation:

answer: a) y=-8x+5

a) m= -8

b) m= -2

c) m= 7

d) m= 6
