<h3>
Answer: Perpendicular</h3>
=========================================================
Work Shown:
Solve the first equation for y
3x+7y = 15
7y = -3x+15
y = (-3x+15)/7
y = (-3/7)x + 15/7
The slope here is -3/7
-------
Solve the second equation for y
7x-3y = 6
-3y = -7x+6
y = (-7x+6)/(-3)
y = (7/3)x - 2
The slope here is 7/3
-------
The slopes -3/7 and 7/3 are not equal, so we don't have parallel lines.
The lines however are perpendicular because the slopes multiply to -1
(-3/7)(7/3) = (-3*7)/(7*3) = -21/21 = -1
7 yellow, 5 green, 3 blue...total of 15
P(yellow party hat) = 7/15
do not replace
P(yellow hat) = 6/14
P(both) = 7/15 * 6/14 = 42/210 which reduces to 1/5 or 0.2 or 20%
Its 0.00032 thats the answer
Answer:
The answer to your question is: x > - 32 / 9
Step-by-step explanation:
2[ -5/2 (3x + 4) < 6 - 3x ] x (2)
-5 (3x + 4) < 12 - 6x
-15x - 20 < 12 - 6x
-15x + 6x < 12 + 30 Simplify
- 9 x < 32 solve for x
x > - 32 / 9 result
