Answer:

Here's one way to do it.

Step-by-step explanation:

-24 ÷ (-4)

-24 is the final number on the number line

-4 means you count by 4s on the number line moving backwards.

Start at 0 facing forward.
Move backwards in steps of four units from 0 to -24.
Count the number of steps you took (six).

Answer: +6 (The sign is + because you are still facing forward).

Answer:

$2$

Step-by-step explanation:

Given:

$-2(1-4x)=3x+8$

Let's distribute the parenthesis

$-2+8x=3x+8$

Let's subtract $-3x$ from both sides

$-2+5x=8$

Let's add $2$ to both sides

$5x=10$

Now, let's divide both sides by $5$ to get $x$ alone

$x=2$

What are the solutions of the equation x^4-9x^2+8=0? Use u substitution to solve.

vodka [1.7K]

Answer:

The answer is the second option

Step-by-step explanation:

Let u=x^2.

$( {x}^{2} ) {}^{2} - 9( {x}^{2} ) + 8( {x}^{2} ) {}^{0}$

${u}^{2} - 9u + 8$

$(u - 1)(u - 8)$

$u = 1$

$u = 8$

Set this equal to x^2

${x}^{2} = 1$

$x = 1$

$x = - 1$

${x}^{2} = 8$

$x = 2 \sqrt{2}$

$x = - 2 \sqrt{2}$
