Answer:

$\frac{4x+2}{x^2 - 9x + 8} = \frac{4x}{(x-8)(x-1)} + \frac{2}{(x-8)(x-1)}$

Step-by-step explanation:

Given

$\frac{4x+2}{x^{2}-9+8 } = \frac{A}{()(x-1)} + \frac{B}{()(x-8)}$

Required

Fill in the gaps

Going by the given parameters, we have that

$\frac{4x+2}{x^{2}-9+8 } = \frac{A}{()(x-1)} + \frac{B}{()(x-8)}$

$x^2 - 9x + 8$ , when factorized is $(x-1)(x-8)$

Hence; the expression becomes

$\frac{4x+2}{(x-1)(x-8)} = \frac{A}{(x-8)(x-1)} + \frac{B}{(x-1)(x-8)}$

Combine Fractions

$\frac{4x+2}{(x-1)(x-8)} = \frac{A + B}{(x-8)(x-1)}$

Simplify the denominators

$4x + 2 = A + B$

By direct comparison

$A = 4x$

$B = 2$

Hence, the complete expression is

$\frac{4x+2}{x^2 - 9x + 8} = \frac{4x}{(x-8)(x-1)} + \frac{2}{(x-8)(x-1)}$

6(2x+4)=4(3x+6) solve and show work

Afina-wow [57]

Answer:

0=0

Step-by-step explanation:

6(2x+4)=4(3x+6)

Step 1: Simplify both sides of the equation.

6(2x+4)=4(3x+6)

(6)(2x)+(6)(4)=(4)(3x)+(4)(6)(Distribute)

12x+24=12x+24

Step 2: Subtract 12x from both sides.

12x+24−12x=12x+24−12x

24=24

Step 3: Subtract 24 from both sides.

24−24=24−24

Does the equation x^2+y=144 define y as a function of x?

11Alexandr11 [23.1K]

The given equation is

$x^2 + y = 144$

First we solve for y, and for that, we have to islolate y, that is

$y= 144-x^2$

And it pass the vertical line test. So here y is a function of x .

So we can define the given equation as y as a function of x .
