To solve for x in the inequality -70 ≥ -10x, we need to isolate x. We can do this by dividing both sides of the inequality by -10.
Here's the step-by-step:
−70 ≥ −10x
First, divide both sides by -10. Remember, when you divide or multiply both sides of an inequality by a negative number, the direction of the inequality sign changes.
So dividing by -10, we get:
(−70)/(-10) ≤ (−10x)/(-10)
This simplifies to:
7 ≤ x
Now, to graph the solution on a number line, you would draw a number line and shade all the numbers to the right of 7, including the number 7 since the inequality includes the equal to portion (≤ means "less than or equal to"). To indicate that 7 is included in the solution set, we use a closed dot at 7 on the number line.
Here's a simple representation of the number line:
```plaintext
5 6 7 8 9 10
|---------|---------●---------|---------|---------|
```
The closed dot at 7 represents that 7 is part of the solution, and the line extending to the right represents all the values greater than or equal to 7 are included in the solution set.
Solve for xx and graph the solution on the number line below.
minus, 70, is greater than or equal to, minus, 10, x
