Keep the fraction and square root the numerator and the denominator. This will give you 3/4. Finally, apply the negative. You should get -3/4. :)

Which is the correct coefficient matrix for this system? 3x - 4y = 12 x + 6y = 10
Stels [109]

The coefficients of x and y in the first equation are 3 and -4, respectively.

The coefficients of x and y in the second equation are 1 and 6, respectively.

The coefficient matrix lists these coefficients in order on successive rows, so it will be ...

\left[\begin{array}{cc}3&-4\\1&6\end{array}\right]

Answer the question
Naya [18.7K]
Your answer would be x=3. You would start by combining like terms such as 5x and -7x and getting -2x. Then you would move the +5 to the other side by subtracting it from both sides. You would get -6=-2x. After that you would divide -2 on both sides and since they are both negatives, it would be a positive 3.

If line a is perpendicular to line b and the slope of line a is 7 whats the slope of line b
amm1812

Answer:

If a line is perpendicular to another line, that means that the slope is completely opposite that of the original line.  The first thing that we do to the slope is we negate the number which means that if we have a slope of -7 our slope because 7 in this step.  In our case our slope is 7 so in this step it becomes -7.

Moving onto the second part which is to get the reciprocal of the number which means that if we have \frac{1}{2} then we would switch it to 2.  In our case our number is -7 so we would make that into a fraction like this -\frac{1}{7}.

In conclusion, our final slope of the perpendicular line is -\frac{1}{7}.
