Find all the numbers such that the sum of twice the number and 8 is greater than or equal to tour times the number​

Mathematics

Wittaler [7]3 years ago
5 0

Answer:

Step-by-step explanation:

Let the number = x

2x + 8 ≥ 4x                   Subtract 2x from both sides.

8 ≥ 4x - 2x                    Combine

8 ≥ 2x                           Divide by 2

8/2 ≥ 2x/2                    Combine

4 ≥ x

What this means is that the largest value the x can have is 4. Any number greater that 4 will make the use of ≥ incorrect.

The answer is a. 1/7
The length of QR is 3 sqrt(2) which means half of that is where the median intersects. Since the triangle formed is a right triangle with legs that are equal. The vertex angles are 45°, we can get the coordinates of the point of intersection which is (4.5,3.5).
So, 
m (slope) = (3.5-3)/(4.5-1) = 1/7
