First you had to multiply with negatives seven and negative five. You can also multiply by the numbers.

-7*-5=-35

Final answer: \boxed{=-35}

35/5=7

7*5=35

5*7=35

35/7=5

Hope this helps!

And thank you for posting your question at here on brainly, and have a great day.

Hello!

Let’s do it step-by-step, shall we? Don’t worry! These problems can be a bit tricky but you’ll get it in no time! It’s really simple.

So, we have (-7)(-5)

This means that the problem will be multiplied because of the parentheses. They substitute the multiplication sign.

So, we have -7 (multiplied by) -5= 35

So your answer would be 35. Hope this helps :) and good luck!

Find the equation of the line that contains the given points. P1(−8, 5), P2(−8, −5)
zavuch27 [327]
\bf \begin{array}{lllll}
&x_1&y_1&x_2&y_2\\
%   (a,b)
&({{ -8}}\quad ,&{{ 5}})\quad 
%   (c,d)
&({{ -8}}\quad ,&{{ -5}})
\end{array}
\\\\\\
% slope  = m
slope = {{ m}}= \cfrac{rise}{run} \implies 
\cfrac{{{ y_2}}-{{ y_1}}}{{{ x_2}}-{{ x_1}}}\implies \cfrac{-5-5}{-8-(-8)}
\\\\\\
\cfrac{-10}{-8+8}\implies \stackrel{und efined}{\cfrac{-10}{0}}

that simply means, is a vertical line, check the picture below.
