To solve for x, you simplify both sides of the equation and then isolate the variable.

<em>10x + 12 = $72.00</em>
<em>x = 6</em>

Six people attended the concert.
<em>Check the answer:
(10 • 6) + 12 = 72.00
60 + 12 = 72.00
_____________________________________________________________
<u>Answer: x = 6</u></em>

<em>f</em> is a function defined by

{(-3, 1), (-2, 2), (-1, -3), (0, -1), <u>(1, 3)</u>, (2, -2), (3, 0)}

so <em>f</em> (1) = 3. Then

<em>h</em> (<em>g</em> (<em>i</em> (<em>j</em> (<em>f</em> (1))))) = <em>h</em> (<em>g</em> (<em>i</em> (<em>j</em> (3))))

<em>j</em> is defined by

{(-3, 0), (-2, 1), (-1, 2), (0, -1), (1, -2), (2, 3), <u>(3, -3)</u>}

so <em>j</em> (3) = -3, and

<em>h</em> (<em>g</em> (<em>i</em> (<em>j</em> (<em>f</em> (1))))) = <em>h</em> (<em>g</em> (<em>i</em> (-3)))

And so on. Next you have <em>i</em> (-3) = 2, then <em>g</em> (2) = 0, and finally, <em>h</em> (0) = 0, so your answer is correct.

What is the equation of a line that passes through the points (–3, 4) and (2, 8)?
Mrac [35]

Answer:

\frac{y - 4}{x - ( -  3)}  =  \frac{8 - 4}{2  -  (-  3)}  \\  \frac{y - 4}{x + 3}  =  \frac{4}{5}  \\ 5(y - 4) = 4(x + 3) \\ 5y - 20 = 4x + 12 \\  \boxed{4x - 5y + 32 = 0}

<h2>4x-5y+32=0 is the right answer.</h2>
