Step-by-step explanation:
Direct variation:
Inverse variation:
We have
cross multiply
it's an inverse variation
Answer:
Step-by-step explanation:
First, cross multiply.
(x+4)(x+1)=4(2x+2)
x^2+5x+14=8x+8
x^2-3x-4=0
(x+1)(x-4)=0
x+1=0 x-4=0
x = -1, x=4
I used geogebra for this. I hope this helps
45 minutes as you only have to divide 60 by 4 and then multiply it times 3
Subtract x2 from x1 to get -7. After that subtract y2 from y1 to receive 3. That leaves you with -7/3 which simplified is -2.1333*
