14. Add the line times the outside number
X(X+4)= (2√3)^2
X^2+4X= 4√9
X^2+4X= 4times 3
X^2+4X=12
X^2+4X-12=0
(X+6)(X-2)=0
X=-6 X=2
Answe can't be negative so it's X=2

The diameter of a circle is 14in. Find its area in terms of pie(urgent)
Soloha48 [4]

The area of a circle is equal to:

\pi \times {r}^{2}

r = 1/2 the diameter

1/2 of 14 is 7

7 squared is 49

<em><u>The area is 49π</u></em>

Find the inverse of the function and then determine whether the inverse is a function.
klemol [59]

as you already know, we start off by doing a quick switcheroo on the variables, and then we solve for y to get the inverse,


\bf y=x^2+4\implies \stackrel{switcheroo}{x = y^2+4}\implies x-4=y^2\implies \pm\sqrt{x-4}=\stackrel{f^{-1}(x)}{y}


and if you run a vertical line test on that expression, you'll find that it doesn't pass it, meaning is not a function.

Write the equation of the line given the slope and the y-intercept. Type your answer in the box without skipping any spaces. m =
Over [174]

The equation of a line given the slope and y-intercept is given as;

             m(x-x₁) = (y-y₁)

∴equation of line with m = 2 and y-intercept = (0,3) =

     2(x - 0) = (y - 3)

 = 2x - 0 = y - 3

  making y the subject obtains y = 2x + 3.

so, equation of the line: y = 2x + 3.

Pls helps fast!!
Aleks [24]

Answer:

Option B is correct.

Step-by-step explanation:

We have given a triangle ABC and EDC please look at the figure

We can see that AE and BD are transversal therefore, ∠EAB=∠AED being alternate interior angles

And ∠ACB=∠DCE are vertically opposite angles hence, equal

So, by AA similarity postulate the above to triangles are similar

ΔABC \sim ΔEDC

Therefore, Option B is correct that is Triangle ABC is similar to triangle EDC , because m∠3 = m∠4 and m∠1 = m∠5

NOTE: m∠3 = m∠4 corresponds to m∠ACB=m∠DCE

And m∠1 = m∠5 corresponds to m∠EAB=m∠AED
