Answer: c. –6 ≤ x ≤ 3


Step-by-step explanation:

Given situation: All real numbers at least –6 and at most 3.

Let x be a real number

and "at least" means the minimum value , so 'x' must b greater than or equal to the minimum value i.e. –6 ≤ x .

"at most" means the maximum value , so 'x' must be smaller than or equal to the maximum value i.e. x ≤ 3 .

then according to the given situation,

All real numbers at least –6 and at most 3.

⇒ –6 ≤ x ≤ 3

Novay_Z [31]

Answer:

13.9

Step-by-step explanation:

Use the distance formula:

d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}\\\\d = \sqrt{(7 - (-5))^2 + (-4-3)^2}\\d = \sqrt{(12)^2 + (-7)^2}\\d = \sqrt{144 + 49}\\d = \sqrt{193}\\

The square root of 193 rounded to the nearest tenth is 13.9.

A biker moves 2.5 times faster than a walker. They started moving simultaneously in the same direction from the same point. In t
saveliy_v [14]

Answer:

The speed of the biker is 15

Step-by-step explanation:

First, you call the speed of the walker x, and the speed of the biker 2.5x.

Then you know that speed times time equals distance, so you set up and equation. You do x times 2, which is 2x, and then 2.5x times 2, which is 5x. Then, since the distance between them is 18 miles, the equation would be 5x-2x=18. You would get 3x=18, and x is 6. So 6 is the speed of the walker, and 6 times 2.5 = 15, so the speed of the biker is 15.

The amount of money that Li spends on a video game depends on how many game he purchases. if Li has at most $90 to spend on game
siniylev [52]

Answer:

Hence Domain set for function is {0,1,2,3,4}

Step-by-step explanation:

Given:

Total amount spend =90

22.5 $ each game cost

To Find:

What is domain for the function

Solution:

Now domain mean all possible value for input so that it gives real output as per condition mentioned

So Our condition is that li spends money on video game depends on how many game he purchases

so  total money  spent on game is output

i.e in order to get that much amount of games.

If he spends 22.5 $ for each game and Total amount spent is 90

So 90/22.5=4 Now amount of game he would purchase will be 4

i.e range for lil is 0 to 4 wiht 90 $ in hand

So Domain set will be ranging from{0,1,2,3,4}
