Answer 1

Ответ:

2

Объяснение:

при y=1

x=4

ответ 2

Answer 2

To find the values of x for which the function y = 0.5x - 1 is less than y = 1 (y < 1), we need to compare the two equations and solve for x.

1. y = 0.5x - 1
2. y = 1

Since we want to find the values of x where y from the first equation (y = 0.5x - 1) is less than 1 (y < 1), we can set up the inequality:

0.5x - 1 < 1

Now, let's solve for x:

Add 1 to both sides of the inequality:

0.5x < 1 + 1

0.5x < 2

Finally, divide both sides by 0.5 to isolate x:

x < 2 / 0.5

x < 4

So the correct answer is: 2) x < 4
