tamaranim1 [39]

So it went from 30 to 35, or 5 bucks, if we take 30 to be the 100%, what is 5 off of it in percentage?

$\bf \begin{array}{ccll}
amount&\%\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
30&100\\
5&p
\end{array}\implies \cfrac{30}{5}=\cfrac{100}{p}\implies p=\cfrac{5\cdot 100}{30}$

Which ordered pair is NOT a solution to the inequality in the graph?

aalyn [17]

Given:

The inequality is

$y\leq 3x+2$

To find:

The ordered pair that is NOT a solution to the inequality in the graph.

Solution:

We have,

$y\leq 3x+2$

Checking the inequality for (0,0), we get

$0\leq 3(0)+2$

$0\leq 2$

So, the equality is true for (0,0). it means (0,0) is a solution of given inequality.

Checking the inequality for (-2,-4), we get

$-4\leq 3(-2)+2$

$-4\leq -6+2$

$-4\leq -4$

So, the equality is true for (-2,-4). It means (-2,4) is a solution of given inequality.

Checking the inequality for (0,2), we get

$2\leq 3(0)+2$

$2\leq 2$

So, the equality is true for (0,2). It means (0,2) is a solution of given inequality.

Checking the inequality for (-3,4), we get

$4\leq 3(-3)+2$

$4\leq -9+2$

$4\leq -7$

This statement is not true. So, the equality is false for (-3,4). It means (-3,4) is not a solution of given inequality.

Therefore, the correct option is D.

Simplify the rational expression. state any excluded values. <br><br> x^2-3x-10/x+2

Natali5045456 [20]

Answer:

The answer to your question is x - 5 or x = 5

Step-by-step explanation:

$\frac{x^{2} -3x - 10}{x + 2}$

1.- Factor the numerator

x² - 3x - 10

find 2 numbers that added equal -3 and multiply equal -10.

These numbers are -5 and + 2

(x - 5)(x + 2)

2.- Simplify

$\frac{(x - 5)(x + 2)}{x + 2)}$

Delete (x +2) in both numerator and denominator

3.- Result x - 5

x = 5
