A circle is sometimes/always/never

grigory [225]

A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.

Step-by-step explanation:

Two Circles are said to be similar if all the linear measurements of the circles are proportional.

Lets consider if two circles have a certain ratio of their radii, , it definitely mean that all the other corresponding ratios will also have that same ratio.

<u>Concentric circles are defined as the circles which have a common center. The area between the two concentric circles having difference in their radii is Known as annulus.</u>

<u></u>

The most important property of a circle is that all points on the circle are equidistant (i.e. having the same distance) from the center point.

<u>A circle is always similar to another circle, because we can always map one onto the other using only dilations and rigid transformations.</u>

Lera25 [3.4K]

Answer:

2

Step-by-step explanation:

The first equation is a circle. The second equation is a line. If you make the line cross the circle, it'll really only hit 2 points.

Solve using the quadratic formula:<br> 3x=2x^2-2

Tomtit [17]

Answer:

$x=2\\x=-\frac{1}{2}$

Step-by-step explanation:

1) Move terms to the left side.

$3x=2x^{2} -2\\3x-(2x^{2}-2)=0$

2) Distribute.

$3x-(2x^{2} -2)=0\\3x-2x^{2} +2=0$

3) Rearrange terms.

$3x-2x^{2} +2=0\\-2x^{2} +3x+2=0$

4) Common factor.

$-2x^{2} +3x+2=0\\-(2x^{2} -3x-2)=0$

5) Divide both sides of the equation by the same term.

$-(2x^{2} -3x-2)=0\\2x^{2} -3x-2=0$

6) Use the quadratic formula.

$x=\frac{-b+\sqrt{b^{2}-4ac } }{2a}$

Once in standard form, identify a, b, and c from the original equation and plug them into the quadratic formula.

$2x^{2} -3x-2=0\\a=2\\b=-3\\c=-2$

$x=\frac{-(-3)+\sqrt{(-3)^{2} -4*2(-2)} }{2*2}$

7) Simplify.

Evaluate the exponent

$x=\frac{3+\sqrt{(-3)^{2}-4*2(-2) } }{2*2}$

$x=\frac{3+\sqrt{9-4*2(-2)} }{2*2}$

Multiply the numbers

$x=\frac{3+\sqrt{9-4*2(-2)} }{2*2}$

$x=\frac{3+\sqrt{9+16} }{2*2}$

Add the numbers

$x=\frac{3+\sqrt{9+16} }{2*2}$

$x=\frac{3+\sqrt{25} }{2*2}$

Evaluate the square root

$x=\frac{3+\sqrt{25} }{2*2} \\x=\frac{3+5}{2*2}$

Multiply the numbers

$x=\frac{3+5}{2*2}$

$x=\frac{3+5}{4}$

8) Seperate the equations.

To solve for the unknown variable, separate into two equations: one with a plus and the other with a minus.

$x=\frac{3+5}{4}$

$x=\frac{3-5}{4}$

9) Solve.

Rearrange and isolate the variable to find each solution.

$x=2\\x=-\frac{1}{2}$

What is the answer to -9-8x=-2(7+4x)

Misha Larkins [42]

-9-8x=2(7+4x)

First you are going to distribute the 2 to (7+4x) then you will get both Xs on one side

-9-8x=2(7+4x)
-9-8x= 14+8x
+8x. +8x

=-9=14+16x

Now subtract 14 from both sides

9=14+16x
-14 -14

-23=16x

Divide by 16

Your answer will be x= -23/16
