user100 [1]2 years ago

5 0

Answer:

Step-by-step explanation:

Given

21 ≤ - 3(x - 4) < 30 ← divide all 3 intervals by - 3

Remembering to reverse the direction of the signs as a result of dividing by a negative quantity

- 7 ≥ x - 4 > - 10 ← add 4 to each interval

- 3 ≥ x > - 6, that is

- 6 < x ≤ - 3 → A

Solve using quadratic formula 6x^2-x=2

Nadya [2.5K]

$6x^2-x=2\implies 6x^2-1x-2=0 \\\\[-0.35em] ~\dotfill\\\\ ~~~~~~~~~~~~\textit{quadratic formula} \\\\ \stackrel{\stackrel{a}{\downarrow }}{6}x^2\stackrel{\stackrel{b}{\downarrow }}{-1}x\stackrel{\stackrel{c}{\downarrow }}{-2}=0 \qquad \qquad x= \cfrac{ - b \pm \sqrt { b^2 -4 a c}}{2 a}$

$x = \cfrac{ -(-1) \pm \sqrt { (-1)^2 -4(6)(-2)}}{2(6)}\implies x = \cfrac{1\pm\sqrt{1+48}}{12} \\\\\\ x = \cfrac{1\pm\sqrt{49}}{12}\implies x = \cfrac{1\pm 7}{12}\implies x = \begin{cases} \frac{8}{12}\to &\frac{2}{3}\\[1em] -\frac{6}{12}\to &-\frac{1}{2} \end{cases}$

I think there is a bug here. They can't be whole numbers.
