Answer:

X= -10

Step-by-step explanation:

15=3x-15

Minus the numbers on the other side of the variable

15=3x-15

-15 -15

=0 -30

In algebra the - before a number gets counted as a negative so -15 minus 15 = -30

Then since we still have 3x we divide it by -30 because its being tiems by a number we cant see

so -30/3 = -10

Thats how we found X.

Answer:

Solve for x

Step-by-step explanation:

we already know that 30 minus 15 is 15 so something times 3 equals 30. 10x3=30. so x = 10.

15 =3(10)-15

15= 3(10) -15 =30 -15

15 = 30 - 15

15=15

So, again, the answer is 10.

Is the Mandelbrot set locally connected?

MariettaO [177]

Answer:

Step-by-step explanation:

It is conjectured that the Mandelbrot set is locally connected. This famous conjecture is known as MLC (for Mandelbrot locally connected). By the work of Adrien Douady and John H. Hubbard, this conjecture would result in a simple abstract "pinched disk" model of the Mandelbrot set. In particular, it would imply the important hyperbolicity conjecture mentioned above.

The work of Jean-Christophe Yoccoz established local connectivity of the Mandelbrot set at all finitely renormalizable parameters; that is, roughly speaking those contained only in finitely many small Mandelbrot copies.[19] Since then, local connectivity has been proved at many other points of {\displaystyle M}M, but the full conjecture is still open.

What is the y-value of the point of intersection of y=2sinx-cosx and y=cosx over the interval 0≤x≤pi/2 ? a. 0 b. (square root of

horsena [70]

We have that

<span>y=2sinx-cosx
y=cosx
</span>over the interval 0≤x≤pi/2-------> 0≤x≤1.57

using a graph tool
see the attached figure

the solution in the given interval is the point (pi/4, 0.707)
the y-value of the point of intersection is 0.707 -----> √2/2

the answer is the option
<span>b. (square root of 2)/2</span>
