Answer:

\boxed{x^2 - 6x + 9 - y^2}.

Step-by-step explanation:

We start by applying the difference of squares to the expression:

((x-3)-y)((x-3)+y) = (x-3)^2 - y^2.

Now we apply the square of a binomial to the first term:

(x-3)^2 - y^2 = x^2 - 2 \times 3 \times x + 3^2 - y^2 = x^2 - 6x + 9 - y^2.

So the answer is:

\boxed{x^2 - 6x + 9 - y^2}.

I need help please help me thanks please
Vitek1552 [10]

so we have a table of values, with x,y coordinates, so let's use any two of those points to get the slope of the table and use the point-slope form to get its equation

~\hspace{2.7em}\stackrel{\textit{let's use}}{\downarrow }\qquad \stackrel{\textit{and this}}{\downarrow }\\\begin{array}{|lr|r|r|r|r|}\cline{1-6}x&0&1&2&3&4\\y&-1&3&7&11&15\\\cline{1-6}\end{array}\\\\[-0.35em]\rule{34em}{0.25pt}\\\\(\stackrel{x_1}{1}~,~\stackrel{y_1}{3})\qquad(\stackrel{x_2}{4}~,~\stackrel{y_2}{15})

\stackrel{slope}{m}\implies\cfrac{\stackrel{rise}{\stackrel{y_2}{15}-\stackrel{y1}{3}}}{\underset{run}{\underset{x_2}{4}-\underset{x_1}{1}}}\implies \cfrac{12}{3}\implies 4\\\\\\% point-slope intercept\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}{3}=\stackrel{m}{4}(x-\stackrel{x_1}{1})\\\\\\y-3=4x-4\implies y = 4x-1\implies \blacktriangleright  y = 4x+(-1)\blacktriangleleft

If two distinct lines intersect, which is NOT necessarily true?
Thepotemich [5.8K]

Answer:

Option (b) is the answer.

Step-by-step explanation:

If two distinct lines intersect

Then they are not parallel because parallel lines never intersect they go hand in hand

But since, we need to tell which is not true

So, option A is discarded.

Option (c) and (d) are also true hence, discarded.

Option (b) is correct that is the lines are perpendicular this is not true. hence, considered

Therefore, option (b) is the answer.
