Answer:

1 / 8², B

Step-by-step explanation:

8 / 8³

8³ = 8*8*8

divide the numerator and denominator by 8.

1 / 8*8

This is equal to:

1 / 8²

The answer is B.

Which of the following equations is a direct variation?<br> y=3X+2<br> y=5<br> y=2x<br> y=8x+6

Alex

$direct \: varition \: means \: y \alpha x \\ it \: becomes \: y = kx$
So y=2x is the only answer that fit y=kx, while k=2

Find the slope-intercept form of the equation of the line that passes through the point P and makes angle with the positive x-

SIZIF [17.4K]

Answer:

The answer is " $y= -x+7$ "

Step-by-step explanation:

If $\bold{\theta = 135^{\circ}}$

point: $p=(2,5)$

Formula:

$\to m= \tan \theta \\\\\to (y-y_1)= m(x-x_1)$

$\to m= \tan \ 135^{\circ} = -1\\\\\to x_1= 2\\\\\to y_1=5$

Put the value in the above formula:

$\to y- 5 = -1(x-2)\\\\\to y- 5 = -x+2\\\\\to x+y = 5+2\\\\\to x+y=7$

$\to y= -x+7$
