1.) Draw a line segment somewhere on the paper and label it line m.
2.) Mark a point somewhere on the paper but not on the line, label this point r.
3.) Fold the paper on point r. Make sure the line is folded in top of itself
4.)Trace the fold with your pencil/pen
5.) label the intersection point P

If g(x)*x+1/x-2 abd h(x)=4-x, what is the value of (g*h) (-3)
kifflom [539]

Answer:

The value of (g*h) (-3)  is =-\frac{112}{3}

Step-by-step explanation:

If g(x) = x+\frac{1}{x}-2 and h(x)=4-x

We have to find (g*h) (-3)

First multiply g(x) with f(x)

(x+\frac{1}{x}-2)\times (4-x)

Distribute\:parentheses

=x\cdot \:4+x\left(-x\right)+\frac{1}{x}\cdot \:4+\frac{1}{x}\left(-x\right)+\left(-2\right)\cdot \:4+\left(-2\right)\left(-x\right)

\mathrm{Apply\:minus-plus\:rules}

+\left(-a\right)=-a,\:\:\left(-a\right)\left(-b\right)=ab

=4x-xx+4\cdot \frac{1}{x}-\frac{1}{x}x-2\cdot \:4+2x

simplify

=-x^2+6x+\frac{4}{x}-9

Now, put x= -3 in above expression

=-(-3)^2+6(-3)+\frac{4}{-3}-9

=\left(-\frac{1}{3}-3-2\right)\left(4+3\right)

=\left(-\frac{16}{3}\right)\left(4+3\right)

=7\left(-\frac{16}{3}\right)

=-\frac{16}{3}\cdot \:7

=-\frac{112}{3}

Therefore, the value of (g*h) (-3) is -\frac{112}{3}

Brainly use a matrix to find the solution to the system of equations -8x-8y=-16 6x-9y=-108
Mama L [17]
We want to use a matrix to solve
-8x - 8y = -16
6x - 9y = -108

Before solving, simplify the equations as follows:
Divide the first equation by -8 to obtain
x + y = 2             (1)
Divide the second equation by 3 to obtain
2x - 3y = -36       (2)

In matrix form, the equations are
\begin{bmatrix}1&1\\2&-3\end{bmatrix} \begin{\bmatrix} x\\y\end{bmatrix}=\begin{bmatrix}2 \\ -36 \end{bmatrix}

The determinant of the matrix is
D = (1)(-3) - (1)(2) = -5

Use Cramer's Rule.
x =  \frac{1}{D} det(\begin{bmatrix}2&1\\-36&-3 \end{bmatrix} ) =  \frac{1}{-5} (-6+36) = -6
Similalrly, 
y= \frac{1}{-5} det(\begin{bmatrix} 1&2\\2&-36\end{bmatrix} ) = \frac{1}{-5}(-36-4) =8

Answer:  (-6, 8)  or x = -6, y = 8
