In this question , we have the following equations

8x-9y+13z=11 \\  -8x-5y+5z=15 \\ 3x+4y-8z=-10

And we have to put these in matrix form.

We make a matrix for the numbers of the left side, a matrix for the variables x , y ,z , and a matrix for the numbers on the right side , that is

\begin{bmatrix}
8 & -9 & 13\\  -8 & -5 &5 \\  3 & 4 & -8
\end{bmatrix} *\begin{bmatrix}
x\\ y  \\ z \    \end{bmatrix} = \begin{bmatrix}
11\\ 15  \\ -10
\end{bmatrix}

And that's the required matrix.

Solve -2x+3=-3x+2 and is it no solution <br>One solution or infinitely many solutions. ​
Alex73 [517]

Answer is =-1

implifying

-2x + 3 = -3x + 2

Reorder the terms:

3 + -2x = -3x + 2

Reorder the terms:

3 + -2x = 2 + -3x

Solving

3 + -2x = 2 + -3x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '3x' to each side of the equation.

3 + -2x + 3x = 2 + -3x + 3x

Combine like terms: -2x + 3x = 1x

3 + 1x = 2 + -3x + 3x

Combine like terms: -3x + 3x = 0

3 + 1x = 2 + 0

3 + 1x = 2

Add '-3' to each side of the equation.

3 + -3 + 1x = 2 + -3

Combine like terms: 3 + -3 = 0

0 + 1x = 2 + -3

1x = 2 + -3

Combine like terms: 2 + -3 = -1

1x = -1

Divide each side by '1'.

x = -1

Simplifying

x = -1

Choose the scatter plot that shows a negative correlation.
Alenkinab [10]

Negative correlation between two variables means when x is increasing but y is decreasing or vice versa.

First graph of suffered animals and children shows a positive slope which means if age of child increasing then numbers of suffered animal is also increasing.So, the first graph show a positive correclation.

Second graph of survey of adults doesn't represnt any distinct relationship as the data scattered randomly everywhere in the graph. So, it's showsa very week correlation.

Third graph of speed and MPG shows a negative slope as speed is increasing then MPG is decreasing. So, the third graph (speed and MPG) shows a negative correlation.

The limit as h approaches 0 of (e^(2+h)-e^2)/h is ?
Whitepunk [10]
<span>If you plug in 0, you get the indeterminate form 0/0. You can, therefore, apply L'Hopital's Rule to get the limit as h approaches 0 of e^(2+h),
which is just e^2.
</span><span><span><span>[e^(<span>2+h) </span></span>− <span>e^2]/</span></span>h </span>= [<span><span><span>e^2</span>(<span>e^h</span>−1)]/</span>h

</span><span>so in the limit, as h goes to 0, you'll notice that the numerator and denominator each go to zero (e^h goes to 1, and so e^h-1 goes to zero). This means the form is 'indeterminate' (here, 0/0), so we may use L'Hoptial's rule:
