Answer:
see explanation
Step-by-step explanation:
The equation of 2 quantities in direct proportion is
y = kx ← k is the constant of proportionality
1
y = - 4x ← in standard form
with k = - 4
2
= 2 ( multiply both sides by x )
y = 2x ← in standard form
with k = 2
3
= 3 ( multiply both sides by y )
x = 3y ( divide both sides by 3 )
x = y ← in standard form
with k = 
The answer would be 3z(5x + 7y)
Answer:
56.8 miles
Step-by-step explanation:
4/5 = 0.8
Get like terms together. you might have to move across the equals sign
3x-x=-6+82
2x=76
x=38
Answer: it’s -5/2 I think. You might have to dive idea if it doesn’t let you put the fraction, but that is the rise over run or y over x
