Answer:
He only accepts jobs that last 4 or more hours. Or A
Step-by-step explanation:
We have that
<span>y = –x + 8
and
4x + 4y = 12
we know that
if two lines are perpendicular
so
m1*m2=-1
step 1
find the slope of the lines
</span>y = –x + 8 -------> m1=-1
4x + 4y = 12-----> x+y=3 (divided by 4 all expression)
y=3-x
m2=-1
therefore
m1=m2
the lines are parallel
the answer is<span>
No; their slopes are not opposite reciprocals.
</span>
see the attached figure
2 + 2 = 4
4 is the answer :)
The supplement of 89° is the angle that when added to 89° forms a straight angle (180° ).
Answer:
b = 2 or b = 7
Step-by-step explanation:
b/(b-7) - 2/b = 7/ (b-7)
b * b - 2(b - 7) = 7 * b
b^2 - 2b + 14 = 7b
b^2 - 9b + 14 = 0
(b - 2)(b - 7) = 0
b - 2 = 0; b = 2
b - 7 = 0; b = 7
Answer
b = 2 or b = 7
