-2/3x - 3/4x =5/6.

Find the common denominator for -2/3x and -3/4x. The common denominator is 12.

Multiply by 4 for -2/3x. (-2)(4)/3(4)x=-8/12x

Multiply by 3 for -3/4x. (-3)(3)/4(3)x=-9/12x

-8/12x-9/12x=5/6

-17/12x=5/6

Multiply both sides by -12/17

(-17/12x)(-12/17)=5/6(-12/17)

Cross out -17 and 17, divide by 17. Then becomes 1.

Cross out -12 and -12, divide by -12. Then becomes 1.

1*1*x=x

Cross out 6 and -12, divide by 6. 6/-6=1, -12/6=-2

5*-2/17=-10/17

Answer: -10/17

common denumerator is 12

-8/12x-9/12x=10/12

-17/12x=10/12 <<multiply by 12

-17x=10

x=-0.59

Answer:

y - 1 = 3 ( x - 2)

Step-by-step explanation:

The formula for point slope form is y-y1=m(x-x1)

Just substitute the given information into the equation to get your answer.

(reminder m=slope, y1=the given y value, x1= the given x value)

Solve for 'p'

Darina [25.2K]

$\left(\dfrac{9a^{-4}}{25}\right)^p=\dfrac3{5a^2}$
$\left(\dfrac9{25a^4}\right)^p=\dfrac3{5a^2}$

One way to find $p$ is to notice that the part on the left hand side within the parentheses can be written as a square:

$\dfrac9{25a^4}=\dfrac{3^2}{5^2(a^2)^2}=\left(\dfrac3{5a^2}\right)^2$

So you could write

$\left(\left(\dfrac3{5a^2}\right)^2\right)^p=\left(\dfrac3{5a^2}\right)^{2p}=\dfrac3{5a^2}$

Since these two expressions are equal, and the bases are the same, you know the exponents must be equal, with the exponent on the right hand side being 1. So $2p=1$ , or $p=\dfrac12$ .
