Answer:

-2<x $\leq$ 11

Step-by-step explanation:

The line spans from -2 to 11 so we know that those are the values that will be in our expression. -2 has an open circle, therefore, we do not include that value. So any value greater than -2 but not equal to -2 is included. -11 has a closed circle that ends the line segment. This means that any value less than 11 or greater than 11 is included. Therefore the expression would be x is greater than -2 and less than or equal to 11.

For a-b, reduce to the least non-negative residue

Olenka [21]

Answer:

a. 6

b. 9

Step-by-step explanation:

a. The product modulo 7 can be found from the product of the individual numbers modulo 7:

(88·95·36·702) mod 7 = (88 mod 7)·(95 mod 7)·(36 mod 7)·(703 mod 7) mod 7

= (4·4·1·3) mod 7 = 48 mod 7 = 6

b. Powers of 4 mod 11 repeat with period 5:

4 mod 11 = 4

4^2 mod 11 = 5

4^3 mod 11 = 9

4^4 mod 11 = 3

4^5 mod 11 = 1

So, 4^83 mod 11 = 4^3 mod 11 = 9

Elena-2011 [213]

Answer:

15 shirts.

Step-by-step explanation:

A 20% discount means you still pay 80% of the price.

x represents the number of shirts that can be bought.

(20 x (1-0.2) )x = 240 or (20 x .8)x = 240

16 x = 240

x = 240/16 = 15
