Answer:
9. -64
11. -225
Step-by-step explanation:
'number' will be x
2x+3=7
subtract 3 on both sides:
2x=4
divide by 2 on both sides:
x=2
So the answer to the problem is A
The slope of a line is
where
is the difference and
and
are the values.
In this case, the difference in
is 10 and the difference in
is 0
And division where the denominator being 0 leads to the answer being Undefined or Infinity as the line is directly on the
axis.
The answer of 8610÷42 is 205
