Which equation represents a line that is perpendicular to the line represented by 2x-y=7?
1 answer:
The correct question is
<span>Which equation represents a line that is perpendicular to the line represented by 2x - y = 7?
A. y = -1/2x + 6
B. y = 1/2x + 6
C. y = -2x + 6
D. y = 2x + 6
</span>
we know that
if two lines are perpendicular
so
the slopes
m1*m2=-1
we have
<span>2x-y=7-------> y=2x-7------------> slope m1=2
find slope m2
m2=-1/m1------> m2=-1/2
the slope m of the perpendicular line must to be -1/2
so
the answer is
</span>y = -1/2x + 6<span>

Answer: 0.7</h3>
Work Shown:
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.3 + 0.5 - 0.1
P(A or B) = 0.8 - 0.1
P(A or B) = 0.7
I’m pretty sure the answer is A
The answers is 200 or 201
I think it’s b i’m sorry if it’s wrong
