Is the rule ax+by=d the same as y=mx+b?

No, they are not the same.

If you made y the subject for each of them:

ax + by = d

by = -ax + d

y = -(a/b)x + (d/b)

which may not be the same as

y = mx + b

since b is already a fixed variable.

But I'm not sure if your question is just asking about whether ax + by = d can be expressed as linear form. If it was asking that, then the working above shows that it can be expressed in linear form (y = mx + b)

because 1.2 isnt half of 6 duh

i think it's ф or x=6,-6

step-by-step explanation:

-x^2=-36

x^2=-36

ф

or

if you mean by : -(x^2)=-36

it'll be: x^2=36

x=6,x=-6

hope it'll ! have a good day!

you for asking!
