0.156 because you take 3.9 (fudge) and divide it by 25 (guests)
Step-by-step explanation:
x2-8x-3x+24=0
x(x-8) 3(x+8)
(x-8)(x+8)
x-8=0 or x+8=0
x=8. x= -8
1) Add 9 to both sides
2) You get 15y<45
3) Divide by 15 on both sides
4) You get y<15
Remember that < is less than and > is greater than
Also note that when you divide by a negative number, you need to flip the inequality symbol.
The product of -8. (-8)= 64
Answer:
(8,1)
Step-by-step explanation:
When flipping across the y axis, the y coordinate stays the same, while the x coordinate changes it's sign.
(x,y) - > (-x,y)
(-x,y) -> (x,y)
