Answer: 3/13
Step-by-step explanation:
There are 12 cards above the jack in a deck of 52 cards
Probability = 12/52 = 3/13
F(x) = 50x + 20
y= 50x + 20
120 = 50(2) + 20
0 <(or equal to) x <(or equal to) 2
85 is the correct answer.
50 - 40x ≥ 200
-40x ≥ -300
x ≤ 7.5
40$ can be withdrawn from the account 7 weeks if she wants to maintain a balance at least 200<span />

Answer: C) perpendicular</h3>
Explanation:
Each equation given to you is in y = mx+b form (aka slope intercept form).
The slope m is what we'll focus on.
The first equation has slope of 1, while the second equation has slope -1.
The two slopes multiply to -1. This is a property of any pair of perpendicular lines, as long as neither line is vertical nor horizontal.
Or you could note that -1 is the negative reciprocal of 1, or vice versa.
So there are a few options to see why the lines are perpendicular.
