Answer:

$x = 1$ or $x = 2$

Step-by-step explanation:

Given:

$f(x) = 2x \hspace{5mm} \& \hspace{5mm} g(x) = 2^x$

We are to find the values of $x$ such that these two functions are equal.

Substitute $x = 1$ .

We get $f(x) = 2(1) = 2 \hspace{5mm} \& \hspace{5mm} g(x) = 2^{(1)} = 2$

Hence for $x = 1$ we have the functions to be equal.

Now for $x = 2$

$f(2) = 2(2) = 4 \hspace{5mm} \& \hspace{5mm} g(2) = 2^{(2)} = 4$

We see the functions are once again equal.

The table shows conversions of common units of length.

fgiga [73]

Answer:

0.50 miles

Step-by-step explanation:

<em>We can use two unit converters to solve this problem.</em>

1 mile = 1.61 kilometers, and
1000 meters = 1 kilometers

<em>Thus, we can setup the ratio below and solve:</em>

$800 Meter*\frac{1Kilometer}{1000Meter}*\frac{1Mile}{1.61Kilometer}\\=\frac{800*1*1}{1000*1.61}Mile\\=\frac{800}{1610}Mile\\=0.497Mile$

Rounding to 2 decimal places, 800 meters = 0.50 miles.

What is the value of x in the equation StartFraction 4 Over 7 EndFraction (StartFraction 21 Over 8 EndFraction x + one-half) = n

Sliva [168]

Answer:

Step-by-step explanation:

$\dfrac{4}{7}\left(\dfrac{21}{8}x+\dfrac{1}{2}\right)=-2\left(\dfrac{1}{7}-\dfrac{5}{28}x\right)\\\\\text{use the distributive property}\ a(b\pm c)=ab\pm ac\\\\\left(\dfrac{4}{7}\right)\left(\dfrac{21}{8}x\right)+\left(\dfrac{4}{7}\right)\left(\dfrac{1}{2}\right)=(-2)\left(\dfrac{1}{7}\right)-(-2)\left(\dfrac{5}{28}x\right)\\\\\dfrac{4\cdot21}{7\cdot8}x+\dfrac{4\cdot1}{7\cdot2}=-\dfrac{2}{7}+\dfrac{2\cdot5}{28}x\qquad\text{simplify}$

$\dfrac{3}{2}x+\dfrac{2}{7}=-\dfrac{2}{7}+\dfrac{5}{14}x\qquad\text{multiply both sides by 14}\\\\(14)\left(\dfrac{3}{2}x\right)+(14)\left(\dfrac{2}{7}\right)=(14)\left(-\dfrac{2}{7}\right)+(14)\left(\dfrac{5}{14}x\right)\qquad\text{simplify}\\\\(7)(3x)+(2)(2)=(2)(-2)+(1)(5x)\\\\21x+4=-4+5x\qquad\text{subtract 4 from both sides}\\\\21x+4-4=-4-4+5x\\\\21x=-8+5x\qquad\text{subtract}\ 5x\ \text{from both sides}\\\\21x-5x=-8+5x-5x\\\\16x=-8\qquad\text{divide both sides by 16}$

$\dfrac{16x}{16}=\dfrac{-8}{16}\qquad\text{simplify}\\\\\boxed{x=-\dfrac{1}{2}\to x=-0.5}$
