PLS HELP ME WITH MATH

arsen [322]

Answer:

slope is 3

Step-by-step explanation:

Slope = $\frac{change in y }{change in x }$

change in y = (13-7), (19-13), (25-19), (31-25)

change in y = 6

Change in x = (4-2), (6-4), (8-6), (10-8)

Change in x = 2

Therefore slope = $\frac{6}{2}$

Slope = 3

Complete the square to factor X^2 +10X=-8

ella [17]

Answer: $x=\sqrt{17}-5$ and $x = -\sqrt{17}-5$

Step-by-step explanation:

Alright, lets get started.

The given equation is :

$x^{2} +10x = -8$

Adding 8 in both sides, it will become

$x^{2} +10x + 8 = -8 +8$

$x^{2} +10x + 8 = 0$

To make it perfect square, we need to add 25 and subtract 25

$x^{2} +10x + 8 +25-25= 0$

$x^2+10x+25+8-25=0$

$(x+5)^2+8-25=0$

$(x+5)^2-17=0$

Adding 17 in both sides

$(x+5)^2=17$

taking square root

$x+5=\sqrt{17}$

So,

$x=\sqrt{17}-5$ and $x = -\sqrt{17}-5$ .. Answer

Hope it will help :)
