Answer is 3x because u do 12-9 which gets three and since it was originally 12x and you don’t know what X is you just put the x on the 3 and get 3x

4. A triangle has vertices (-2,-3) (3,5) and (8,-1) .

Hatshy [7]

Given:
Vertex 1 (-2,-3)
Vertex 2 (3,5)
Vertex 3 (8,-1)

Reflection across the x-axis rule (x,y) → (x -y)
Vertex 1 (-2,-3) → (-2,-(-3)) → (-2,3)
Vertex 2 (3,5) → (3,-5)
Vertex 3 (8,-1) → (8,-(-1)) → (8,1)

Rotation 90° clockwise (x,y) → (y,-x) *I'm assuming the original triangle was rotated and not the reflection.
Vertex 1 (-2,-3) → (-3,-(-2)) → (-3,2)
Vertex 2 (3,5) → (5,-3)
Vertex 3 (8,-1) → (-1,-8)

Find the circumference of the circle. Use

Y_Kistochka [10]

Answer:

<h2>51.5 miles</h2>

Solution,

Diameter(d)= 16.4 miles

Radius(r)= 16.4/2= 8.2

Circumference of the given circle= ?

Now,

Circumference of circle:

$2\pi \: r$

= 2 * 3.14 * 8.2

= 51.496

= 51.5 miles

Hope this helps...

Good luck on your assignment..

An initial investment of $350 is worth $429.20 after six years of continuous compounding. Find the

ValentinkaMS [17]

Answer:

Interest Rate : 0.0346 or 3.46%

Step-by-step explanation:

• 429.2=350*(1+x)^6

• 429.2/350= (1+x)^6

•(429.2/350)^(1/6)= 1+x

•(429.2/350)^(1/6)-1= x

Check work:

350*(1+0.0346)^6=429.2

This seems to be a reflection over the 'y' axis. Notice that the 'x' coordinates of points U and V are x =2 in the original figure, and then, 'x' coordinates of U' and V' are x = -2

All 'y' coordinates for the transformated figure (S'T'U'V'W') are the same that the original figure (STUVW), but the 'x' coordinates are exactly the opposite

This transformation is :

$(x,y)\rightarrow(-x,y)$
