The cube root of x^2.

If you look at a regular square root of a number, that would be the same as x^(1/2) See the pattern?

It has one X-intercept. Graph it on Desmos and you can see the line, and then it becomes obvious it is one x-intercept.

Find the center and radius of (x + 9)^2 + (y + 6)^2 = 9.

VARVARA [1.3K]

You can do this by comparing your equation to the general form of equation of a circle

( x - a)^2 + (y - b)^2 = r^2 where (a,b) is the centre and r = radius:-
(x + 9)^2 (y + 6)^2 = 9

so (a,b) = (-9,-6) and r = 3

so the answer is B

Which equation in slope-intercept form represents a line that is parallel to y=−4x−5 and passes through the point (0,0)?

IrinaK [193]

Answer:

$\displaystyle y = -4x$

Step-by-step explanation:

0 = 0 ± b

$\displaystyle 0 = b \\ \\ y = -4x$

* Parallel Lines have SIMILAR RATE OF CHANGES [SLOPES], so −4 remains the way it is.
