Answer:

x > -24

Step-by-step explanation:

-x/4 < 6

Multiply each side by -4, remembering to flip the inequality

-x/4 *-4> 6*-4

x > -24

$\boxed{\large{\bold{\red{ANSWER~:) }}}}$

x>-24

<h2>Step-by-step explanation:</h2>

$\sf{\dfrac{-x}{4}$

$\sf{\dfrac{-x}{4}×(-4)>6×(-4) }$

$\sf{ x>-24 }$

$\bold{ Note - }$

By multiply negetive number,we need to change the side of the inequality.

What would be the answer for this question. 1/2 x - 18 = 2

Goryan [66]

Answer:

x = 40

Step-by-step explanation:

1/2x - 18 = 2

1/2x = 2 + 18

1/2x = 20

x = 20 / 1/2

x = 20 * 2/1

x = 40

The slope is rise over run
The rise is 1
The run is 2
So the slope would be 1/2

. Use the quadratic formula to solve each quadratic real equation. Round

Liono4ka [1.6K]

Answer:

A. No real solution

B. 5 and -1.5

C. 5.5

Step-by-step explanation:

The quadratic formula is:

$\begin{array}{*{20}c} {\frac{{ - b \pm \sqrt {b^2 - 4ac} }}{{2a}}} \end{array}$ , with a being the x² term, b being the x term, and c being the constant.

Let's solve for a.

$\begin{array}{*{20}c} {\frac{{ 5 \pm \sqrt {5^2 - 4\cdot1\cdot11} }}{{2\cdot1}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 5 \pm \sqrt {25 - 44} }}{{2}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 5 \pm \sqrt {-19} }}{{2}}} \end{array}$

We can't take the square root of a negative number, so A has no real solution.

Let's do B now.

$\begin{array}{*{20}c} {\frac{{ 7 \pm \sqrt {7^2 - 4\cdot-2\cdot15} }}{{2\cdot-2}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 7 \pm \sqrt {49 + 120} }}{{-4}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 7 \pm \sqrt {169} }}{{-4}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 7 \pm 13 }}{{-4}}} \end{array}$

$\frac{7+13}{4} = 5\\\frac{7-13}{4}=-1.5$

So B has two solutions of 5 and -1.5.

Now to C!

$\begin{array}{*{20}c} {\frac{{ -(-44) \pm \sqrt {-44^2 - 4\cdot4\cdot121} }}{{2\cdot4}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 44 \pm \sqrt {1936 - 1936} }}{{8}}} \end{array}$

$\begin{array}{*{20}c} {\frac{{ 44 \pm 0}}{{8}}} \end{array}$

$\frac{44}{8} = 5.5$

So c has one solution: 5.5

Hope this helped (and I'm sorry I'm late!)

Colt1911 [192]

Answer:

2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.

Step-by-step explanation:

<em>Easy way to take one of the vertices and apply the transformations</em>

1. Rotate the triangle 90º counterclockwise about the origin and then translate it 10 units left and 9 units down.

False

2. Rotate the triangle 90º clockwise about the origin and then translate it 10 units left and 9 units down.

True
(-3, 3) → (3, 3) → (3 - 10, 3 - 9) = (-7, -6)

3. Rotate the triangle 90º counterclockwise about the origin then translate it 1 unit up.

False

4. Rotate the triangle 90º clockwise about the origin then translate it 1 unit up.

False
