-2a - 4 > -8
add 4 to both sides

-2a - 4 + 4 > -8 + 4
-2a > -4

divide both sides by -2 AND change the direction of the sign because we're dividing by a negative

a < 2

ANSWER: a < 2

Hope this helps! :)

Hey there!

Firstly, we have to “add” the number “4” on each of your sides

Like: -2a -4 + 4> -8 +4
Cancel: -4 + 4 because it will give you “0”
Keep: -8+4 because it gives you “-4” and we have paid it off with -2a

Like: -2a>-4

Divide each of the sides by “-2”

Like: -2a/2 > -4/-2

Cancel: -2a/2 because it gives us “1”

Keep: -4/-2 because that’ll give us the answer on the left side of the inequality

So, a < 2 would be your answer

Good luck on your assignment and enjoy your day

How do you factor this? x^{2} + 5 x- 9 = ?
Oksanka [162]
x^2+5x-9\\\\a=1;\ b=5;\ c=-9\\\Delta=b^2-4ac\\\\\Delta=5^2-4\cdot1\cdot(-9)=25+36=61 > 0\\\\x_1=\dfrac{-b-\sqrt\Delta}{2a}\ and\ x_2=\dfrac{-b+\sqrt\Delta}{2a}\\\\\sqrt\Delta=\sqrt{61}\\\\x_1=\dfrac{-5-\sqrt{61}}{2\cdot1}=\dfrac{-5-\sqrt{61}}{2}\\\\x_2=\dfrac{-5+\sqrt{61}}{2\cdot1}=\dfrac{-5+\sqrt{61}}{2}\\\\x^2+5x-9=\left(x-\dfrac{-5-\sqrt{61}}{2}\right)\left(x-\dfrac{-5+\sqrt{61}}{2}\right)
