X + 4y = 9   Convert to  slope / intercept form:-

y  = (-1/4)x + 9/4

so the line perpendicular to this will have a slope -1 /(-1/4) = 4

so our equation will be y - y1 = 4(x - x1) where x1y1 is a point on the line.
x1 = 8 and y1 = -3:-
y - -3 = 4(x - 8)

y = 4x - 35
-4x + y = -35 is the answer

Simply sixteen squared divided by four cubed
FinnZ [79.3K]
You mean "Simplify 16²÷4³?"
16²=16*16,  16= 4*4
4³=4*4*4
so:
Simplify: <u>16²</u>  = <u>16*16</u> =  <u>4*4*4*4</u> = <u>4</u> = 4
               4³  =  4*4*4 =    4*4*4     1
OR
256 ÷ 64 = 4

Given that:

James is 6 times older than his friend Zach, if Zach added 8 to his age and multiplied this sum by 3 .

To find:

The equation that can be used to solve for zach's age.

Solution:

Let the age of zach be Z.

Zach added 8 to his age = Z+8

And multiplied this sum by 3 = 3(Z+8)

James is 6 times older than his friend Zach = 6Z

Now,

6Z=3(Z+8)

6Z-3Z=24

3Z=24

Divide both sides by 3.

Z=8

Therefore, the required equation is 6Z=3(Z+8) is age of zach is 8 years.
