Answer:
21
Step-by-step explanation:
<->
To do this you need to put it in function form.
Here's the work
2y-3x = 8
2y-3x = 8
+3x +3x
2y = 3x+8
/2. /2
y = 3/2x + 8
To find perpendicular you multiply the slope the the opposite reciprocal.
y = -2/3x + 8
Then the +8 doesn't really matter now
Slope that is perpendicular is -2/3x
Answer:
4 cups of milk are used with 3 cups of water
Step-by-step explanation:
Area = Length x width.
1st equation: Area = 72 x 52
2nd equation: Using distributive property by rewriting 52 as a sum of two numbers. 30 + 22 = 52
So now we get the second equation of: 72(30+22)
