Answer:
=3
Step-by-step explanation:
Combine like terms 3-6x=-15
Subtract 3 from both sides of the equation -6x=-18
divide both sides by 6 x=3
3/10 because 2/5 is also equal to 4/10 so therefore 3/10 is smaller than 4/10
<span>The parent cosine function can be transformed and translated. So, from the basic function cos(x) we can obtain function acos(bx+c). In our case, a=3- amplitude, b=10- the period change and c=-pi- the phase shift. So, the parent cosine function is mutiplied with 3 (which gives the amplitude of the function, 3*0.5=1.5). The period of the function is changed, and is 2pi/b=2pi/10=pi/5 and the cos(x) is phase shifted for c/b=-pi/10.</span>
The answer to this very difficult question is 10 :)
When a function is reflected, it must be reflected over a line
The new function is: 
The equation is given as:
The rule of reflection over the y-axis is:
So, we have:
Rewrite as:
Hence, the new function is:
