Answer:
It's B
Step-by-step explanation:
Answer:
4/5
Step-by-step explanation:
Convert 4y+5x=16 to slope intercept form
4y=-5x+16
y=-5/4+4
Perpendicular line has slope of 4/5
You get the following two equations:3x + 5y = 1372x + 7y = 161
If you have two equations, you can solve for two variables.
Solve for x in the first equation:
x = (137-5y)/3
Then substitute this in for "x" in the 2nd equation.
2[ (137-5y) / 3 ] + 7y = 161
Now you can solve for "y"
(274/3) - (10/3)*y + 7y = 161
(11/3)*y = 161 - (274/3)
y = 19
Now that you have "y", you can solve for "x"
2x + 7(19) = 161
x = 14
CDs cost $14 and DVDs cost $19 each
32/8 = 16/4 = 8/2 = 4/1 that's as far as it can be reduced. Hope this helped :)
