The answer is -8. Just plug in the options for x and add both up to get the full length of the line which is 15

Answer:

x=-8

Step-by-step explanation:

x+15+x+16=15

=) 2x+31=15

=)2x=15-31

=)2x=-16

=) $\frac{2x}{2} =\frac{-16}{2}$ (The 2(s) in $\frac{2x}{2}$ cancel out, leaving x= $\frac{-16}{2}$ , or x=-8

Graph the following inequality on the number line above. 3x < 12

shtirl [24]

We need to isolate x by diving 3 on both sides and you get x<4. To graph this, put an open circle around 4 (because 4 cannot be one of the solutions) and draw an arrow going left because x can be anything below 4

What is the answer to this equation using the quadratic formula?<br> 3x^2+2x+4x=0

o-na [289]

$~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{3}x^2\stackrel{\stackrel{b}{\downarrow }}{+2}x\stackrel{\stackrel{c}{\downarrow }}{+4}=0 \qquad \qquad x= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a} \\\\\\ x= \cfrac{ - (2) \pm \sqrt { (2)^2 -4(3)(4)}}{2(3)}\implies x=\cfrac{-2\pm \sqrt{4-48}}{6}$

$x=\cfrac{-2\pm \sqrt{-44}}{6}\implies x=\cfrac{-2\pm \sqrt{(-1)(2^2)(11)}}{6}\implies x=\cfrac{-2\pm 2~i\sqrt{11}}{6} \\\\\\ x=\cfrac{2(-1\pm i\sqrt{11})}{6}\implies x=\cfrac{-1\pm i \sqrt{11}}{3}$

mind you that it has two complex roots, or imaginary values.
