\dfrac{1}{2}x-2y > -6\ \ \ \ |-\dfrac{1}{2}x\\\\-2y > -\dfrac{1}{2}x-6\ \ \ |change\ signs\\\\2y > \dfrac{1}{2}x+6\ \ \ \ |:2\\\\y > \dfrac{1}{4}x + 3
y=\dfrac{1}{4}x+3\\\\for\ x=0\to y=\dfrac{1}{4}\cdot0+3=3\to(0;\ 3)\\\\for\ x=-4\to y=\dfrac{1}{4}\cdot(-4)+3=-1+3=2\to(-4;\ 2)

Describe a sequence of transformations that transform the graph of the parent function f into the graph of the function g.
olganol [36]

Answer:

The sequence is: Refection across y-axis, Horizontal Shrink, Horizontal Translation and Reflection across x-axis.

Step-by-step explanation:

Since, we are given f(x) = square root x.

The sequence of transformations which transform f(x) into g(x) is given by:

1. Reflection across y-axis i.e. f( x ) to f( -x )

2. Horizontal Shrinking i.e. f( -x ) to f( -x/2 )

3. Horizontal Translation i.e. f( -x/2 ) to f( -x/2 + 3 )

4. Reflection across x-axis i.e. f( -x/2 + 3 ) to -f( -x/2 + 3).

The step by step graphical representation can also be viewed below.

Can you help me with this question in geometry?
Svetllana [295]
I believe this just uses the Pythagorean Theorem. A^2+B^2=C^2. So:
15^2+B^2=25^2. Simplified this is,
225+B^2=625
625-225=400
B^2=400
√ B=<span>√ 400
</span>B=20
