Answer:5
Step-by-step explanation: remeber pemdas
first we do parenthesies(I have bad spelling)
17+6/3-7*2
then we do multiplication and divition, it matters what comes first
17+2-7*2
17+2-14
5
The solution as in where do they intersect? if so, it would be 0.0769 and -0.0769
Answer:
<em>k = - 7.5 </em>
Step-by-step explanation:
Slope "m" of a line through points
(
,
)
(
,
)
is m =
Slopes of perpendicular lines are opposite reciprocal:
= - 1
~~~~~~~~~~~~~~~
The slope of a line through points (0, 7) and (2, 10)
=
=
Slope of perpendicular line through points (3, 5) and (k, 12) is
=
or
=
=
2(k - 3) = - 21
k - 3 = - 10.5
<em>k = - 7.5</em>
