Step-by-step explanation:
You should croos multiply to get 10x = 50 (20) which is 10x = 1000 then divide each side by 10. What do you get for x?
Answer:
yes
Step-by-step explanation:
because we are simply "adding" 2 negative numbers.
-8n + -7 = -7 + -8n
as long as we flip the terms around with their signs, the commutative principle of addition applies.
what we CANNOT do is e.g.
8n - 7 = 7 - 8n
THERE would be a problem.
but again, by also keeping the signs with the terms, it is all OK.
so, yes, we could also do
8n - 7 = -7 + 8n
that is true again.

Step-by-step explanation:
Given a point-slope form equation, we can easily locate of the slope of the linear equation. As a review, the point-slope form can be expressed as

where y₁ and x₁ are the x and y-coordinates of the equation and m is the slope. Seeing that (y-2) = 3(x-1) is already in this form, we can clearly see that the slope of the equation is equal to 3.
