Answer:

\displaystyle (3, 4) \cup (4, 13)

Step-by-step explanation:

We are given the set:

\displaystyle \left\{ x| 3 < x < 13 \text{ and } x \neq 4\right\}

And we want to express this in interval notation.

In words, this reads: all values of <em>x</em> between 3 and 13 and <em>x</em> does not equal 4.

Hence:

\displaystyle (3, 4) \cup (4, 13)

We use parentheses as we do not include the values of 3 and 13 inside our interval. Likewise, since <em>x</em> cannot equal 4, we skip four, but use the union symbol to connect the two intervals.

Sovle the system of linear equations by graphing y=2x-1 y=x+1
lorasvet [3.4K]

Answer:

2x-1=x+1

2x-x=x

1+1=2

x=2

Knowing x's value, we substitute it with the equations

y=x+1

y=2+1

or y=2x-1

y=2(2)-1

y=4-1

y=3

(2,3) are your coordinates :D

How do you do this ?
jeka57 [31]

Answer: 3(x^2 + 4)/(x - 5)(x + 4)

Step-by-step explanation:

To simplify, begin with 3x^2 + 12 by dividing by 3 first: 3(x^2 + 4)

x^2 - x - 20 can be simplified into (x - 5) (x + 4). To find these terms, you have to figure out what two numbers multiply together to equal -20 but also add to -1.
