$y \ge \frac{4x-1}{5}$

Step-by-step explanation:

Given

$4x - 5y \le 1$

Required

Solve for y

$4x - 5y \le 1$

Subtract 4x from both sides

$- 5y \le 1-4x$

Divide both sides by -5 (the inequality sign changes)

$y \ge \frac{1- 4x}{-5}$

$y \ge \frac{4x-1}{5}$

7 and 8

Step-by-step explanation:

Given The sum of two consecutive integers is at least 14.

Let the two consecutive digits be x and x+1

The condition that should be satisfied by these numbers is that their sum must be atleast 14.

$x+(x+1)\geq 14$

$2x+1\geq 14$

$2x\geq 13$

$x\geq \frac{13}{2}$

$x\geq 6.5$

Since x is an integer x=7 and the other digit is 8.
