Explanation

The use of Integrated Circuits (ICs) in the third generation made computers smaller, faster, and cheaper to produce.

This innovation significantly reduced manufacturing costs, making computers more affordable.

The third generation of computers (1964–1971) used Integrated Circuits (ICs) instead of transistors or vacuum tubes.

ICs greatly reduced the size, increased speed, and improved efficiency of computers.

Explanation

Explanation

Explanation

Given the points (x + 5, 8) and (9, y - 6) are equal, we can set up the equations:

x + 5 = 9 ... (1)

8 = y - 6 ... (2)

Solving (1):

x = 9 - 5

x = 4

Solving (2):

y = 8 + 6

y = 14

The values of x and y are x = 4 and y = 14.

Explanation

Given:

(x, 6) = (2, y - 6)

Equating the corresponding components:

x = 2

6 = y - 6

Solving for y:

y = 6 + 6

y = 12

Now, finding x + y:

x + y = 2 + 12

= 14
