Answer:
y = 2x
Step-by-step explanation:
since x and y vary directly then the equation is
y = kx ← k is the constant of variation
to find k use the given condition y = 18 when x = 9
k = = = 2, hence
y = 2x ← is the equation relating x and y
n = 3m
The number is 35.
35 divided by 7 is 5, and 5 plus 7 is 12.

what's it look like if like this |__ right /_ acute \__ obtuse
(1,5) (5,8)
x,y. x,y
Formula: <u>y2-y1</u>
x2-x1
so...
<u>8-5</u><u>=</u> <u>3</u>
5-1 = 4
so... <u>3</u>
