Which value is a solution to the inequality 5x – 1 ≤ –11?
avanturin [10]

Answer:

x≤-2

Step-by-step explanation:

To solve the inequality, we have to add 1 on each side:

5x-1≤11

  +1   +1

And then we get:

5x≤-10.

To find x, we have to divide each side by 5:

5x/5≤-10/5

After we do that, we get:

x≤-2.

The number of ways 8 cars can be lined up at a toll booth would be computed from
stepladder [879]

Answer: c. 8!

Step-by-step explanation:

We know , that if we line up n things , then the total number of ways to arrange n things in a line is given by :-

n! ( in words :- n factorial)

Therefore , the number of ways 8 cars can be lined up at a toll booth would be 8! .

Hence, the correct answer is c. 8! .

Alternatively , we also use multiplicative principle,

If we line up 8 cars , first we fix one car , then the number of choices for the next place will be 7 , after that we fix second car ,then the number of choices for the next place will be 6 , and so on..

So , the total number of ways to line up 8 cars = 8 x 7 x 6 x 5 x 4 x 3 x 2 x1 = 8!

Hence, the correct answer is c. 8! .
