Answer:

The answer to your question is: [1, 3)

Step-by-step explanation:

Data

6x + 7 < 4x + 13 8 + 8x ≤ 17x - 1

6x - 4x < 13 - 7 8x - 17x ≤ - 1 - 8

2x < 6 - 9x ≤ - 9

x < 6/2 x ≥ -9/ -9

x < 3 x ≥ 1

The interval where both inequalities coincide is [1, 3)

Answer:

Step-by-step explanation:

<h3>to understand this</h3><h3>you need to know about: </h3>

algebra

<h3>let's solve:</h3>

$\sf rewrite \: 105 \: as \: 100 + 5 : \\ \sf (100 + 5 {)}^{2}$
$\sf use \: (a + b {)}^{2} = {a}^{2} + 2ab + {b}^{2} \: to \: simplify : \\ \sf {100}^{2} + 2.100.5 + {5}^{2}$
$\sf simplify \: squres : \\ \sf 10000 + 2.100.5 + 25$
$\sf simplify \: multipication : \\ \sf10000 + 1000 + 25$
$\sf simplify \: addition : \\ \sf \: 11025$
