Answer: No Solution


Step-by-step explanation: You plug in x=y-2 into x-y=6. So the problem would be rearranged into (y-2)-y=6. When done correctly the y's cancel out making it a no solution.

Answer:

-6

Step-by-step explanation:

The equation is in slope intercept form

y = mx+b where m is the slope and b is the y intercept

The y intercept is the value when x = 0

The y value is -6 when the x value is 0

y = -4x+ (-6)

Write a slope- intercept equation for a line with given characters m=-4/5, passes through (-4,-5)
aleksandr82 [10.1K]

\bf (\stackrel{x_1}{-4}~,~\stackrel{y_1}{-5})~\hspace{10em} \stackrel{slope}{m}\implies -\cfrac{4}{5} \\\\\\ \begin{array}{|c|ll} \cline{1-1} \textit{point-slope form}\\ \cline{1-1} \\ y-y_1=m(x-x_1) \\\\ \cline{1-1} \end{array}\implies y-\stackrel{y_1}{(-5)}=\stackrel{m}{-\cfrac{4}{5}}[x-\stackrel{x_1}{(-4)}]\implies y+5=-\cfrac{4}{5}(x+4) \\\\\\ y+5=-\cfrac{4}{5}x-\cfrac{16}{5}\implies y=-\cfrac{4}{5}x-\cfrac{16}{5}-5\implies y=-\cfrac{4}{5}x-\cfrac{41}{5}

Y=4x+8x, Solve for x.<br><br> It's x=y/12, I just need to know how to work it out.
Scrat [10]

Step-by-step explanation:

<h2>Answer:-</h2>

\tt{y = 4x+8x}

First, we need to add up the x.

We know that 4+8 = 12, so

\tt{4x+8x=12x}

Now, equating it to y,

\tt{y = 12x}

Now, if I multiply \tt{\dfrac{1}{12}} on both sides,

I get,

\tt{\dfrac{y}{12}= \dfrac{\cancel{12}x}{\cancel{12}}}

Now, as 12 got cancelled , I got the final answer as

\boxed{\tt{x =\dfrac{y}{12}}}

Hope it helps :)

Question 21
horsena [70]

Answer:

<em>A(x) = 6x² + 26x </em>

Step-by-step explanation:

A(x) = 4x ( x + 10 ) - 2x ( 8 ) + \frac{2x(x)}{2} + \frac{2x(x+2)}{2}

A(x) = 4x² + x² + x² + 40x - 16x + 2x

<em>A(x) = 6x² + 26x</em>
