Which system of equations is represented by the graph?

Mathematics
1 answer:
erica [24]3 years ago
4 0

Answer:

               y=x\\\\y=\dfrac{-x+10}{x-4}

Step-by-step explanation:

Red line is increasing and for any x goes the same y, so it's y = x

The blue graph is  y=\dfrac a{x-h}+k, where h=4 and k =-1 and for x=5 also y=5

It gives:

               5=\dfrac a{5-4}+(-1)\\5=a-1\\a=6

So:

      y=\dfrac6{x-4}-1 =\dfrac6{x-4}-\dfrac{x-4}{x-4} =\dfrac{6-x+4}{x-4}=\dfrac{-x+10}{x-4}

46 less than -8 times a number is the same as 8 less than -6 times the number
sertanlavr [38]

Answer:

-19

Step-by-step explanation:

First we set the equation up:

-8X - 46 = -6X - 8

Then we simplify:

-2X = 38

Then we get the answer by dividing 38 by -2:

X = -19

If m< 1 = 10x + 4 and m <2 = 5x-4, find m< 2
BartSMP [9]

Answer:

m<2 = 56°

Step-by-step explanation:

m<1 and m<2 are supplementary angles and sum = 180

so

m<1 + m< 2 = 180

If m< 1 = 10x + 4 and m <2 = 5x-4, find m< 2

10x + 4 + 5x - 4 = 180

15x = 180

  x = 12

m<2 = 5(12) -4 = 56

Answer

m<2 = 56°

If A is an n× n matrix, then det A = det AT . Verify this theorem for 2 × 2 matrices.
Bond [772]

Answer:

Verified

Step-by-step explanation:

Let A matrix be in the form of

\left[\begin{array}{cc}a&b\\c&d\end{array}\right]

Then det(A) = ad - bc

Matrix A transposed would be in the form of:

\left[\begin{array}{cc}a&c\\b&d\end{array}\right]

Where we can also calculate its determinant:

det(AT) = ad - bc = det(A)

So the determinant of the nxn matrix is the same as its transposed version for 2x2 matrices
