<span> <span>-3 and 6
</span></span>
<span>-3 x 6 = -18
-3 + (6) = 3</span>

<span> x2 + 3x - 18 = 0

</span>
<span> (X - 3 ) (X + 6)
</span><span>
To summarize, since -3 and 6 multiply to -18 and add up 3, you know that the following is true:</span>

<span> x2 + 3x - 18 = (X - 3 ) (X + 6)

Find the value of x. x√5=x^4​
Kaylis [27]

Answer:

x=0,\sqrt[6]{5}

Decimal form,

x=0,1.30766048......

Step-by-step explanation:

x\sqrt{5}=x^{4}

x\sqrt{5}-x^{4}=0

(take x as a common factor)

x(\sqrt{5}-x^{3})=0

So,

x=0 and \sqrt{5}-x^{3}=0

for \sqrt{5-x^{3}=0

(add x^{3} for both sides)

\sqrt{5}=x^{3}

x=\sqrt[3]{\sqrt[2]{5} } (multiply 3 by 2)

x=\sqrt[6]{5}

So,

x=0,\sqrt[6]{5}

What in slope-intercept form, can go through the line ( a, 2a) and (-5a, 6a)
Wittaler [7]

Answer:

  • y = -2/3x + 8/3a

Step-by-step explanation:

<u>Given points</u>

  • (a, 2a) and (-5a, 6a)

<u>Slope-intercept form</u>

  • y = mx + b

<u>Slope of the line is</u>

  • m = (6a - 2a)/( -5a - a) = 4a/(-6a) = - 2/3

<u>The y-intercept is:</u>

  • 2a = -2/3*a + b
  • b = 2a + 2/3a
  • b= 8/3a

<u>So the line is:</u>

  • y = -2/3x + 8/3a
