An "inconsistent" system means that there will be no shared point between the two lines. This can happen when the two lines are parallel. To determine which one of the equations would cause this, simply compare the slopes of both equations and see which ones match.

The given equation 4x + 2y = 9 has a slope, m = -2

Among the choices, the equation with the same slope is 2x + y = -6.

Answer:

f[g(2)] = 50

Step-by-step explanation:

<u>Given functions:</u>

$f(x)=2(x+1)^2$

$g(x)=3x-2$

We are asked to determine f[g(2)], which is known as a composite function. When solving composite functions, you always work inside out.

Step 1: Find the value of g(2) by substituting 2 for x in function g(x).

$\implies g(2)=3(2)-2$

$\\\implies g(2)=6-2\Rightarrow g(2)=\boxed{4}$

Step 2: Substitute the found value into the composite function.

$\\\implies f[g(2)]= 2(4+1)^2$

$\implies f[g(2)] = 2(5)^2 \Rightarrow 2(25) \Rightarrow \boxed{50}$

Hence, the value of the composite function f[g(2)] is 50.

Answer:

1. 2

2.3 $\sqrt{5}$

3.8 $\sqrt{6}$

4.2.5 $\sqrt{10}$

Step-by-step explanation:

Remember that $\frac{\sqrt{a}}{\sqrt{b}}$ = $\sqrt{\frac{a}{b} }$ , and $\frac{a}{\sqrt{b}}$ = $\frac{a}{\sqrt{b}}$ * $\frac{\sqrt{b}}{\sqrt{b}}$ = $\frac{a\sqrt{b}}{b}$

1. $\frac{\sqrt{48}}{\sqrt{12} }$ = $\sqrt{\frac{48}{12} }$ = $\sqrt{4}$ =2

2. $\frac{15}{\sqrt{5} }$ = $\frac{15}{\sqrt{5} }$ * $\frac{\sqrt{5}}{\sqrt{5} }$ = $\frac{15\sqrt{5} }{5}}$ =3 $\sqrt{5}$

3. $\frac{48}{\sqrt{6}}$ = $\frac{48}{\sqrt{6}}$ * $\frac{\sqrt{6}}{\sqrt{6}}$ = $\frac{48\sqrt{6}}{6}$ =8 $\sqrt{6}$

4. $\frac{25}{\sqrt{10}}$ = $\frac{25}{\sqrt{10}}$ * $\frac{\sqrt{10}}{\sqrt{10}}$ = $\frac{25\sqrt{10}}{10}$ =2.5 $\sqrt{10}$
