Is there an ordered pair that is a solution to both 4x+3y<12 and -x+3y<-3

Mathematics

Answer:

See below.

Step-by-step explanation:

4x + 3y < 12

-x + 3y < -3

First find where the 2 lines intersect

4x + 3y = 12

-x + 3y = -3

Subtract :

5x = 15

x = 3

and y = -3 + 3 / 3 = 0

So they intersect at the point (3,0).

Therefore there are many  ordered pairs below these 2 lines that satisfy this inequality.

Solve by elimination
multiply top by -1

-2x + y = -4
    x - y  = -2

-x = -6..............so x = 6

2(6) - y = 4
12-y = 4
-8 = -y
so y = 8

(-6,8)

there are 6 married couples at a party. at the start of the party every person shakes hands once with every other pserson except
mestny [16]

Answer:

60 hand shakes.

Step-by-step explanation:

We have been given that there are 6 married couples at a party.

This means there are 12 people in total.

We know that number of handshakes for n people is given by formula \frac{n(n-1)}{2}.

We are also told that at the start of the party every person shakes hands once with every other person except his or her spouse.

So formula for this problem would be \frac{n(n-1-1)}{2} or \frac{n(n-2)}{2}.

Since total numbers of people is party is 12, so we will get:

\frac{12(12-2)}{2}

6*10

60

Therefore, there will be 60 hand shakes at the party.

Liliana wants to write an equivalent expression for n + 3 minus 5 n + 6. Which of her attempts uses the algebraic properties cor
torisob [31]

Answer:

Option A.

Step-by-step explanation:

The given equation is

n+3-5n+6

Liliana wants to write an equivalent expression.

It can be written as

n+(3-5n)+6

Using commutative property, we get  

n-5n+3+6             [\because A+B=B+A]

Using associative property, we get

(n-5n)+(3+6)             [\because A+(B+C)=(A+B)+C]

Using distributive property, we get

(1-5)n+(3+6)             [\because An+Bn=(A+B)n]

Using addition property, we get

-4n+9

Therefore, the correct option is A.
