Answer:

x=6

Step-by-step explanation:

Every point on a vertical line has the same x-value. Use the x-value of the point to find the equation of the vertical line.

Find a 2 × 2 matrix b ≠ o and b ≠ i2 such that ab = ba, where a = 1 7 0 1 . b =

riadik2000 [5.3K]

If $\mathbf A$ is invertible, then we can simply choose $\mathbf B=\mathbf A^{-1}$ because for any invertible matrix $\mathbf X$ by definition we must have $\mathbf{XX}^{-1}=\mathbf X^{-1}\mathbf X=\mathbf I$ .

We have $\det\mathbf A\neq0$ , as

$\det\mathbf A=\begin{vmatrix}1&7\\0&1\end{vmatrix}=1\times1-0\times7=1$

which means $\mathbf A$ is non-singular and has an inverse. The inverse itself would be

$\mathbf A^{-1}=\dfrac1{\det\mathbf A}\begin{bmatrix}1&0\\-7&1\end{bmatrix}^\top=\begin{bmatrix}1&-7\\0&1\end{bmatrix}$

HELP NEEDED!!! WILL MARK BRAINLIEST!!!

Answer:

$x(x + 1)$

Step-by-step explanation:

$\frac{2x + 1}{ \frac{1}{x} + \frac{1}{x + 1} }$

Make denominators same:

$\frac{2x + 1}{ \frac{x + 1}{x(x + 1)} + \frac{x}{(x + 1)} }$

Add the numerators:

$\frac{2x + 1}{ \frac{x + 1 + x}{x(x + 1)} }$

$\frac{2x + 1}{\frac{2x + 1}{x(x + 1)} }$

Apply the rule:

$\frac{a}{ \frac{b}{c} } = \frac{a \times c}{b}$

Therefore,

$\frac{(2x + 1)\times x(x + 1))}{2x + 1}$

Cancel out common factor of 2x+1:

$x(x + 1)$

Write each polynomial function in standard form , classify it by degree and determine the end behavior of its graph Y=12-x^4

Dmitry_Shevchenko [17]

In standard form, zero is always on the right:
y = 12 - x^4
y + x^4 - 12 = 0

End behavior:
As x approaches ∞, y approaches -∞
As x approaches -∞, t approaches -∞
