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.
It is zero
the answer is 5.3 x 10^0
because 10^1 would force you to move the decimal place to make it 53
I hope this helps!
Answer: 625
Explanation:
250+(75*5)
250+375=625
3n + n = 40
4n = 40
n = 40/4
n = 10 <==
