That's false. If x=1, the function equals zero. Further: note that x may not equal -1, as the denominator would in that case be zero.

Express it in slope-intercept form.

GREYUIT [131]

Answer:

y = (2/3)x -1

Step-by-step explanation:

The line crosses the y-axis at -1, so that is the y-intercept.

From that point. the next grid intersection is 3 units to the right and 2 units up, so the slope is ...

m = rise/run = 2/3

The slope-intercept form of the equation of a line is ...

y = mx +b . . . . . where m is the slope (2/3) and b is the y-intercept (-1)

Your line has equation ...

y = (2/3)x -1

Please simplify 1,056=6(x+19)

bulgar [2K]

Answer: x = 157

Step-by-step explanation:

$1056=6\left(x+19\right)$

Switch sides:

$6\left(x+19\right)=1056$

Divide both sides by 6:

$\frac{6\left(x+19\right)}{6}=\frac{1056}{6}$

Simplify:

$x+19=176$

$x+19-19=176-19$

$x=157$

Simplify the question above

andrey2020 [161]

Answer:

$1 + \frac{3}{x}$

Step-by-step explanation:

1) Rewrite x² - 9 in the form a² - b² where, a = x and b = 3.

$\frac{ {x}^{2} - {3}^{2} }{ {x}^{2} - 3x}$

2) use difference of squares: a² - b² = ( a + b ) (a - b).

$\frac{(x + 3)(x - 3)}{ {x}^{2} - 3x}$

3) Factor out the common term x.

$\frac{(x + 3)(x - 3)}{ x(x - 3)}$

4) Cancle out x - 3 .

$\frac{x + 3}{x}$

5) Simplify.

$1 + \frac{3}{x}$

Therefor, the answer is 1 + 3/x.
