x-\ Kathryn's\ points\\\\
y-\ Michael's\ points\\\\
 \left \{ {{x+y=425} \atop {y+70=2x\ \ | subtract\ 70}} \right. \\\\  \left \{ {{x+y=425} \atop {y=2x-70}} \right. \\ substitution\ method\\\\
x+2x-70=425\\\\
3x-70=425\ \ | add\ 70\\\\
3x=495\ \ \ | divide\ by\ 3\\\\
x=165\\\\
y=2x-70=2*165-70=330-70=260\\\\
Kathryn\ scored\ 165\ points\ and\ Michael\ 260

Find the missing lengths of the sides.
Ulleksa [173]

Answer:

The second bubble

Step-by-step explanation:

In a 30 60 90 triangle as shown here a is always 1/2 the hypotenuse (Which the hypotenuse is 6) and then just add \sqrt{3} to the end of it to get b

<em>So, lets demonstrate</em>

a = 1/2 * 6 = 3

b = a*\sqrt{3} = a\sqrt{3} = 3\sqrt{3}

So,

a = 3

b = 3\sqrt{3}

What is the effect on the graph of the function f(x) = x2 when f(x) is changed to f(x − 6)?
suter [353]

Answer:

Horizontal translation in the +x direction.

Step-by-step explanation:

A function of the form f(x) experiments an horizontal translation when the following substitution is applied:

x \to x + a, where a \in \mathbb{R}

If a > 0, the function is translated in the -x direction, whereas a < 0 is the case for the function being translated in the +x direction.

The effect on the graph can be defined by a composition between two function:

f(x) = x^{2}, g (x) = x-6

f\,\circ\,g\,(x) = (x-6)^{2}

The resulting expression represents a horizontal translation in the +x direction.

Finally, we plot f(x) (red) and f\,\circ g\,(x) (blue) by a graphing tool and proved the certainty of this theory.
