Answer:
-4m-2 Hope I helped
Step-by-step explanation: Remove parentheses.
4m−2−8m
Subtract 8m
from 4m
.
−4m−2
Keep in mind that a coordinate is in the form (x, y), so if you plug those values into the equation y=3x+1, you get 1=3(4)+1, simplified to 1=13, which is an untrue statement. However, I'm assuming you mean that the value of y is 4 and x is 1, which would be written as (1, 4). This would be the solution to this equation because 4=3(1)+1 is 4=4 which is a true statement.
You reverse the inequality when you divide both sides by a negative number.
example:
-5x>45 (you divide both sides here by -5 to get the value of x)
answer:
x<9 (notice inequality has been has been reversed)
If you know the total length, and the length of one part, and you're trying to find the other part, just subtract.
81-53=28
bc=28
