Solve each equation by taking square roots<br><br> 2n^2 -8=-33

densk [106]

$2n^2 -8=-33$

$
2n^2=-33+8
 
$ $Add \ 8 \ to \ both \ sides$

$2n^2=-25$

$n^2=- \dfrac{25}{2}$ $Divide \ both \ sides \ by \ 2$

$n=+ \sqrt{ -\dfrac{25}{2} }$ <span> $Take \ the \ square \ root \ of \ both \ sides$
</span>
$n=+ \sqrt{ \dfrac{5i}{ \sqrt{2}}}$

Choose the graph which represents the solution to the inequality. 12x + 4 ≤ -8

user100 [1]

Answer:

<h2> $x\leq -1$ </h2>

Step-by-step explanation:

Steps:

$12x+4-4\leq -8$

Subtract 4 from both sides:

$12x+4-4\leq -8-4$

Simplify:

$12x\leq \frac{-12}{12}$

Divide both sides by 12:

$\frac{12x}{12} \leq \frac{-12}{12}$

Simplify:

$x\leq -1$

Find the value of X in X-X³=17

Karolina [17]

Answer:

Step-by-step explanation:

Step1: find the interval of roots. Consider -3 and -2

$f(-3) = -7$

$f(-2) = 18 >0$

Hence, the root must be on [-3,-2]

Step2: consider the middle point -2.5

$f(-2.5) = 3.875 >0$

Then, the root must be on [-3, -2.5]

Step 3: Repeat step 2 by finding the value of f at the middle point -2.75

$f(-2.75) = -1.0468$

Step 3: Repeat step 2 by finding the value of f at the middle point of the interval [-2.75,-2.5] which is -2.625

$f(-2.625) = 1.537 >0$

Step4: Repeat step 2 on [-2.75, -2.625]

Repeat step 2 until you got the root which is -2.701
