Answer:
(-2,-110)
Step-by-step explanation:
First solve for x
20x−70=70x+30
x= -2
Now substitute x for -2
y=20x−70
y=20(-2)-70
y = -110
Step-by-step explanation:

Answer:
4x + 3y + 9 = 0
Step-by-step explanation:
When a slope of a line and a point passing through it is given then we use slope - one point form to determine the equation of the line.
It is given by:
where 
is the slope of the line and
is the point passing through it.
Here, 
and 
.
Substituting in the formula 
<span>t - (-2) = 6
t + 2 = 6
subtract 2 to both sides
t + 2 - 2 = 6 -2
simplify
t = 4</span>
Answer:
Rounded Answer: 0
Not Rounded Answer: -0.00198019802
Step-by-step explanation:
Rounded Answer:
20/101 = 0.19801980198
Round that to 0.2
20/99 = 0.2
0.2-0.2 = 0
Not Rounded Answer:
20/101 = 0.19801980198
20/99 = 0.2
Answer: -0.00198019802
