Answer:
Perpendicular
Step-by-step explanation:
First note:
- Parallel lines have equal slope
- Perpendicular lines have slopes that are negative reciprocal to each other
Lets check, first we need to convert them to slope intercept form (y = mx + b), where m would be the slope.
L1:
4x + 5y = 15
5y = -4x + 15
y = -4/5x + 3
L2:
4y = 5x - 12
y = 5/4x - 3
Slope of L1 is -4/5 and Slope of L2 is 5/4
<em>Are they negative reciprocals of each other? Yes, because multiplying the slopes would give us "-1"</em>

So the lines are Perpendicular
Answer: 3b + 4c = T
Since brownies are three dollars and cupcakes are four, we simply do the amount of items bought multiplied by three or four.
Hope this helps :)
Answer:
6
Step-by-step explanation:
M=30
To find this, you will multiply both sides by 5. 6*5=30
