9y = 6x + 54
divide through by 9:-
y = 6/9y + 54/9

y = 2/3 x + 6 <---- answer

The slope-intercept form is : $y=ax+b$ so all you have to do is solve for y

$^{-}6x+9y=54$ Equation

$9y=6x+54$ Add 6x to both sides

<span> $y= \frac{2}{3}x+6$ Divide by 9 on both sides
</span>
Therefore the linear function is y=2/3x+6

What is the equation in point-slope form for the line parallel to y = -2x - 4 that contains J(-8, 1)?

Aleksandr [31]

The answer is letter b. y - 1 = 2(x + 8)
This can be proofed by the formula of point-slope form.

Sadie simplified the expression √54a^7b^3, where a>=0, as shown: √54a^7b^3= √3^2•6•a^2•a^5•b^2•b=3ab √6a^5b

Tamiku [17]

Answer:

We are to find the error made by Sadie and then find the correct simplification.

The error Sadie made is that she wrote $a^7$ as $a^2 * a^5$ instead of $a^6 * a$ .

The square root of $a^6$ is $a^3$ and so she could have further simplified.

The correct simplification is shown below:

$\sqrt{54a^7b^3} = \sqrt{2 * 3 * 3 * 3 * a^6 * a * b^2 * b} \\ \\= \sqrt{3^2 * a^6 * b^2 * 6 * a * b} \\\\= 3a^3b\sqrt{6ab}$
