"Modulo $m$ graph paper" consists of a grid of $m^2$ points, representing all pairs of integer residues $(x, y)$ where $0\le x, y The graph of$$3x\equiv 4y-1 \pmod{35}$$has a single $x$-intercept $(x_0,0)$ and a single $y$-intercept $(0,y_0)$, where $0\le x_0,y_0<35$.

What is the value of $x_0+y_0$?

is the number L such that

Consider the first 7 multiples of 5:

5, 10, 15, 20, 25, 30, 35

Taken mod 7, these are equivalent to

5, 3, 1, 6, 4, 2, 0

This tells us that 3 is the inverse of 5 mod 7, so L = 3.

Similarly, compute the inverses modulo 7 of 2 and 3:

since 2*4 = 8, whose residue is 1 mod 7;

which we got for free by finding the inverse of 5 earlier. So

and so R = 2.

Then L - R = 1.

we need the options

step-by-step explanation:

b: |12 – x| ≤ 0.25

step-by-step explanation:      

let x be the possible lengths in inches, of the ribbons jaime cut.

we have been given that jaime is cutting strips of ribbon for a project. he tries to cut each piece to be 12 inches long, but sometimes he cuts it too long or too short by as much as 0.25 inch.  

we can represent this information in an inequality as:

by the definition of absolute value function we will get,

upon combining our inequalities we will get,

therefore, the inequality   describes all the possible lengths (x), in inches, of the ribbons jaime cut.
