Answer:

A. (-\infty, -4]\ or\ (2,\infty)

Step-by-step explanation:

Given:

The inequality is given as:

x\leq-4\ or\ x>2

Now, consider the first inequality

x\leq-4

Here, 'x' is less than or equal to -4. The values that are less than -4 are -5, -6, -7... so on. The inequality used is 'less than or equal to'. This means that -4 is included in the solution. So, we use a square bracket (closed interval) at the other end.

The inequality in notation form is thus, (-\infty,-4]

Now, consider the other inequality x>2

The values of 'x' are greater than 2. The values that are greater than 2 are 3, 4, 5... and so on. Also, 2 is not included in the solution. So, we use open interval on either side.

Therefore, x>2 in interval notation form is (2,\infty)

There is a conjunction 'or' used in the inequality. Therefore, the answer is:

A. (-\infty, -4]\ or\ (2,\infty)

The graph on the number line is shown below.

Sam Is 11 years older than Susan the sum of their ages in years is 27 what’s sams age in years
sweet [91]

Answer:

19

Step-by-step explanation:

Let Sam be x

Let Susan be y


x = y+11

x + y = 27

Substitute (x) with (y+11)

(y+11) + y = 27

Solve the equation

2y + 11 = 27

2y = 16

y = 8


Susan's age is 8.

Sam's age is 8 + 11

Sam's age is 19


Hope this helped :)

Ray delivered 3/8 of the newspapers on his route in the first hour and 4/5 of the rest in the second hour what fraction of the n
Temka [501]

Answer:

\frac{1}{2}

Step-by-step explanation:

Let the total number of Newspapers be x

Number of newspapers delivered in first hour of his route= \frac{3}{8} of x

Total number of newspapers delivered in first hour= \frac{3}{8}x

Number of newspapers left= x-\frac{3x}{8}

Number of newspapers left=\frac{8x-3x}{8}

Number of newspapers left=\frac{5x}{8}

Number of newspapers delivered in second hour=4/5 of\frac{5x}{8}

Number of newspapers delivered in second hour=\frac{x}{2}

Fraction of newspapers delivered in second hour is=\frac{1}{2}

Hence, the correct answer is \frac{1}{2}
