Some symbols are missing. I'm assuming you meant to put in a horseshoe symbol like so
If so, then the contrapositive of that would be
which is the final answer.
The tilde sign
means "not" so writing
means "not q" which is the complete opposite of q.
To the percentage of something do $45 times 0.3
0.3 represents the percent of discount
When you do that you should get $13.5
$13.5 just represents the amount you are going to take away from $45, so subtract 13.5 from 45
Answer:
D. $31.5
Answer:
8.68
Step-by-step explanation:
just multiply 124.00 times 0.07 and that's it
Answer:
see explanation
Step-by-step explanation:
Parallel lines have equal slopes
The product of the slopes of perpendicular lines = - 1
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
All the equations given are in slope- intercept form
y = 2x + 1 → with m = 2
y = 
x - 4 → with m =
y = x + 1 → with m = 1
y = - 
x - 3 → with m = -
y = 10 + x → y = x + 10 → with m = 1
Thus
y = x + 1 and y = 10 + x are Parallel since both have m = 1
y = 2x + 1 and y = - x - 3 are Perpendicular since 2 × - = - 1
