Which set of values for x makes the inequality 12−x<7 true
kozerog [31]

Answer:

\{x:x>5\}

Step-by-step explanation:

Given

12 - x < 7

Required

Values of x that make it true

First: solve the inequality.

12 - x < 7

Collect Like Terms

- x < 7-12

- x < -5

Multiply both sides by -1

-1 * - x < -5 * -1

x > 5 --- The inequality changes when multiplied by a negative value

So, the solution implies that the value of x is greater than 5 (i.e. 6, 7, 8..)

Hence, the set is:

\{x:x>5\}

A triangle has sides with lengths of 20 meters, 21 meters, and 29 meters. Is it a right triangle?
coldgirl [10]

Answer:

Yes, the sides form a right triangle.

Step-by-step explanation:

<u>Pythagorean Theorem:</u>

a² + b² = c²

↓

20² + 21² = 29²

║a² = 20² = 400

║b² = 21² = 441

║c² = 29² = 841

↓

400 + 441 = 841

║This equation is true.

↓

Yes, the sides form a right triangle.

Amir stands on a balcony and throws a ball to his dog, who is at ground level. The ball's height (in meters above the ground), x
defon

Answer:

At the moment it is thrown, the height of the ball is 12 meters

Step-by-step explanation:

If the function h(x) = - (x-2) ^ 2 + 16 models the height of the ball x seconds after it is thrown, then by this same function we can know the initial height of the ball at the initial moment.

If we represent the initial time instant as x = 0, then by doing h (0) we will get the initial height, just when the ball is thrown.

h(0) = - (0-2) ^ 2 +16\\ h(0) = - (4) +16\\ h(0) = -4 +16

h (0) = 12 meters.

At the moment it is thrown, the height of the ball is 12 meters

Charlie runs laps around a track. The table shows how long it takes him to run different numbers of laps. How long would it take
geniusboy [140]
There are a couple ways to determine the number of minutes it will take Charlie to run 9 laps, but the easist would be to find out what is happening to each number of laps in order to get the number of minutes. In each case, the number of laps is being multiplied by 5 to get the number of minutes.
9x5=45 minutes.

He is running each lap in 5 minutes.
