Well gradient means "slope" I just found out from searching the web.
First let's put y = 4 + 2x into slope intercept form of y = mx + b
y = 2x + 4
"m" is the slope, in this equation it would be 2.
The slope or "gradient" is 2.

The y-intercept of any equation in slope intercept form is the value of "b"
In this equation, the y-intercept is 4.

Y = 2x + 4 is in the form of y = mx + b, where m is the gradient and b is the y-intercept.

y = 2x + 4
y = mx + b

m = gradient = 2
b = y-intercept = 4

The gradient is 2.
The y-intercept is 4.

Write the geometric sequence that has four geometric means between 1 and 7,776.
Semmy [17]
324 / (1/4) = 7776

You then have to take its 5th root and that's the geometric ratio. Which is 6. 

<span>So the sequence is 1/24, 1/4, 3/2, 9, 54, 324</span>

I need to find side x in its simplest radical form using the special right triangles method
crimeas [40]

Answer:

\sqrt{6}

Explanation:

From the given diagram,

Hypotenuse sde = x

Opposite side = \sqrt{3}

Using the SOH CAH TOA identity

Sintheta = opposite/hypotenuse

Sin 45 = \sqrt{3}/x

x = \sqrt{3}/sin45

\begin{gathered} x\text{ =}\frac{\sqrt[]{3}}{\sin 45} \\ x\text{ = }\frac{\sqrt[]{3}}{\frac{1}{\sqrt[]{2}}} \\ x\text{ = }\sqrt[]{3^{}}\cdot\sqrt[]{2} \\ x\text{ =}\sqrt[]{6} \end{gathered}

Hence the value of x is \sqrt{6}

Answer:

Look if it has 1 regtangle as the base and 4 triangles it is a rectangular pyramid.

If it has 2 circles as the base and a long tube it is a cylinder.

If it has 2 triangles and 3 rectangles it is a triangular prism

Lastly if it 6 sides of rectangles and squares it is a rectangular prism

Help pls its just math :( <br><br>Ik it sucks I hate math too, pls help tho
Umnica [9.8K]

Answer:

x = - 1

Step-by-step explanation:

Given

- 4(3x - 7) = 40 ( divide both sides by - 4 )

3x - 7 = - 10 ( add 7 to both sides )

3x = - 3 ( divide both sides by 3 )

x = - 1
