Answer/Step-by-step explanation:

7x- 4 = -182

<em>Step:</em>

Add 4 to both sides

7x - 4 + 4 = -182 + 4

Simplify

7x = -178

Divide both sides by 7

7x/7 = -178/7

Simplify

x = -178/7

Decimal form = -25.4285714286

Answer:

x = -178/7

Step-by-step explanation:

<em>Given us that:</em>

<em>Which of the following shows the correct solution steps and solution to 7x- 4 = -182 </em>

<em>Thus, the steps are:</em>

<em>Adding 4 to both sides</em>

<em>7x - 4 = -182</em>

<em>       +4       +4</em>

<em>------------------------</em>

<em>7x = -178</em>

<em>Divide both sides by 7</em>

<em>7x/7 = -178/x</em>

<em>Simplify</em>

<em>x = -178/7</em>

<em>Solution - x = -178/7</em>

<h3>Answer:  5040</h3>

Explanation:

There are 7 ways to pick the first place position, then 6 ways for second place, 5 for third, and so on. We count down until we get to 1

7,6,5,4,3,2,1

Multiply out those values to get the final answer. On many calculators this can be done using the factorial button, indicated as an exclamation mark

7! = 7*6*5*4*3*2*1 = 5040

Find the standard form of the equation of the parabola with a vertex at the origin and a focus at (0, -7).
creativ13 [48]
So hmm check the picture below

we know the vertex is at the origin, and the focus point is below it, that means two things, the parabola is vertical and it's opening downwards

notice the distance "p", from the vertex to the focus point, is just 7 units, however, since the parabola is opening downwards, the "p" value will be negative, so p = -7

\bf \textit{parabola vertex form with focus point distance}\\\\&#10;\begin{array}{llll}&#10;(y-{{ k}})^2=4{{ p}}(x-{{ h}}) \\\\&#10;\boxed{4{{ p}}(y-{{ k}})=(x-{{ h}})^2 }\\&#10;\end{array}&#10;\qquad &#10;\begin{array}{llll}&#10;vertex\ ({{ h}},{{ k}})\\\\&#10;{{ p}}=\textit{distance from vertex to }\\&#10;\qquad \textit{ focus or directrix}&#10;\end{array}\\\\&#10;-------------------------------\\\\&#10;4{{ p}}(y-{{ k}})=(x-{{ h}})^2\quad &#10;\begin{cases}&#10;h=0\\&#10;k=0\\&#10;p=-7&#10;\end{cases}\implies 4(-7)(y-0)=(x-0)^2&#10;\\\\\\&#10;-28y=x^2\implies y=-\cfrac{1}{28}x^2

Factor 2x4 - 20x2 - 78.
Airida [17]

Answer:

2x⁴ - 20x² - 78

To factor the expression look for the LCM of the numbers

LCM of the numbers is 2

Factorize that one out

That's

2( x⁴ - 10x² - 39)

Hope this helps

The volume of a cube is 27 cubic meters.<br> What is its surface area, in square meters?
stiks02 [169]

Step-by-step explanation:

the volume of a cube is

side³.

since the volume is 27 m³, the individual side lengths are then the cubic root of 27 = 3 m.

the surface area is 6 squares of 3×3 = 9m², so in total

9 × 6 = 54 m²
