Do the opposite to the x..if it was -2x you plus that
Answer:
y = - 
x - 
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Given
19x + 15y = - 6 ( subtract 19x from both sides )
15y = - 19x - 6 ( divide all terms by 15 )
y = - x - 
, that is
y = - x - ← in slope- intercept form
X and y are the numbers
y>x
sum (addition) of twice a number (2x) and larger number (y) is (=) 145
2x+y=145
difference between them is 55 (y is bigger so it would be x is subtracted from y)
y-x=55
so the equations are
2x+y=145 and
y-x=55
we could add x to both sides in the 2nd equation to obtain
y=x+55, but that doesn't really represent that the difference is 55, though they are the same euation
so I would say C and D only
Answer:
the answer is D
Step-by-step explanation:
They always say to do the problem in parentheses first
