Answer:

±2  sqrt(3) = x

Step-by-step explanation:

12 -x^2 =0

Add x^2 to each side

12 -x^2+x^2 =0+x^2

12 = x^2

Take the square root of each side

±sqrt(12) = sqrt(x^2)

We know that sqrt(ab) = sqrt(a) sqrt(b)

±sqrt(4*3) = sqrt(x^2)

±sqrt(4) * sqrt(3) = x

±2  sqrt(3) = x

Write an equation that represents a horizontal translation 10 units left of the graph of g(x) = |x|
Vika [28.1K]
Answer:  h(x) = |x+10|

---------------------------------------------------------

Explanation:

To shift the graph 10 units to the left, we replace x with x+10. What's really going on is that the xy axis shifts 10 units to the right (because x is now x+10; eg, x = 2 ---> x+10 = 2+10 = 12) so it appears that the graph is moving to the left. The general rule is h(x) = g(x+10). 

So,
g(x) = |x|
g(x+10) = |x+10| ... every x has been replaced with x+10
h(x) = g(x+10)
h(x) = |x+10|

We can use a graphing tool like GeoGebra to visually confirm we have the right answer (see attached). Note how a point like (0,0) on the green graph moves to (-10,0) on the red graph.

If you roll a single six-sided die, what is the propability if rolling an odd number
Natali [406]

If two thirds of a number is 56, what is three- quarters of that number?
Levart [38]

Answer:

63

Step-by-step explanation: Let n represent the number.  If two third of n = 56, n must be 56 times the reciprocal of 2/3 (3/2) 56 time 3/2 = 84.  three quarter of 84 is 84 times 3/4 = 63
