X = the number of months the tire was used
y = the thickness of the tire tread

y = -(3/7)x + 20

Substitute x for 20 (the number of months the tire was used) and solve for y.

The next question: Substitute x for 49 (the number of months the tire was used) and solve for y.

Which number line represents the solution of 4 - 3x > 13?

Oksanka [162]

Answer:

$x$

Step-by-step explanation:

Given inequality:

$4-3x>13$

In order to represent the solution on the number line, we will first solve the given inequality.

We have

$4-3x>13$

Subtracting both sides by 4.

$4-3x-4>13-4$

$-3x>9$

Dividing both sides by -3.

$\frac{-3x}{-3}$ [On dividing both sides by a negative number the sign of the inequality reverses.]

$x$

So, solution of this inequality will range from -3 to -∞

The number line is represented below.
