Answer:
If four friends can eat four cakes in four days, then four friends will eat an average of one cake per day, so each friend will be able to eat 1/4 of a cake per day.
So 10 friends will eat 10/4 of cake per day, or two and a half cakes per day, so they will eat 2,5 * 10 = 25 (twenty-five) cakes per 10 days, assuming they will eat at the same rate

Answer:
0,5X + (-2), but you have to solve it... I give you the equation.
Step-by-step explanation:
In part A you have to find the equation of the line, so you do end - origin and you'll find m. I can only help you with the first one.
so:
(8,2) and (10,3)
(10-8,3-2) = (2,1)
V2/V1= 1/2= 0,5=m (slope of the line)
y= mx+n (change y, x and m with the ones above)
2= 8·0,5+n
2= 4+n
n= 2-4=-2
the equation is: 0,5X + (-2) and then you just have to change x in both equations, the second one is the h(x) adn it will give you the answer to A.
