Write a rule that would allow you to test whether (x,y) is on line ℓ.

Pour expliquer pourquoi la distance entre la fourmilière et chacune des fourmis est constante, on peut diviser les variables par un calculateur et considérer les coordonnées comme une provenance

Explication étape par étape:

Response:

(0,-7)

Detailed explanation:

For any point designated as (x,y)

x represents the abscissa, which can also be referred to as the x-axis coordinate, while

y represents the ordinate, also known as the y-axis coordinate

ordinates are the points along the y-axis.

For any point situated on the y-axis, its x-coordinate will always be 0

given that the ordinate is -7. This indicates that the y-coordinate takes the value of -7

Thus, the coordinates of the point are (0,-7)

Response:

2.33 $

Detailed breakdown:

10x14=140 cents / 2.33$

Answer: x ≥ 3.2 OR x ≤ -0.75

Here's how to solve the compound inequality step-by-step: start by separating it into two inequalities. For the first one, 5x - 4 ≥ 12, add 4 to both sides to remove the constant, leaving 5x ≥ 16. Then divide both sides by 5 to isolate x, resulting in x ≥ 3.2.

Now for the second part, 12x + 5 ≤ -4, subtract 5 from both sides to obtain 12x ≤ -9. Dividing both sides by 12 gives x ≤ -9/12, which simplifies to x ≤ -0.75. So, combining both, the solution is x ≥ 3.2 OR x ≤ -0.75.
