Answer:
Step-by-step explanation:
if the roots are 3 and -6, we can start with:
But the leading coefficient must be 3, we just add a 3 to one of the x's:
But now we have to make sure the roots work again:
So our equation is:
[/tex]f(x)=3x^2+9x-54[/tex]
I’m not quite sure what the question is, but 81 cookies distributed among 44 people would mean that each person gets 0.02 cookies each.
Step-by-step explanation:
the slope = (0+15)/(-1-4)=15/(-5)= -3
the Equation :
y+15= -3(x-4)
or
y+15 = -3x+12
y +3x=12-15
3x + y = -3
so, the correct answer is II only
Answer:
Susan has suggested a correct method to calculate the amount of money
Step-by-step explanation:
Here we must check what each person is calculating. First, we consider Susan's method. She has suggested that we multiply the cost per soda, that is dollars/soda by the number of sodas required, we get the total cost.
Assuming that 18 sodas are required and each costs $0.20, the total cost according to Susan is $3.60.
John suggests we divide the cost of a 12 pack of soda by the number of sodas required. Considering a 12 pack of soda costs $12 and the same amount of sodas, 18, are required, we get that each soda costs $0.66.
Looking at these answers, we see that Susan has suggested a correct method to calculate the amount of money needed to buy a number of sodas. John has suggested the amount each person would have to contribute if everyone at the party was trying to buy a 12-pack of soda; regardless of whether more or less than a 12-pack is required.
The answer would be 252. Here’s why:
You always round up when it’s five (half) or above. 4 or Lower will round it down. In our question here, 62.5 would be rounded up, and 4.08 will be rounded down. This lets us rewrite the question as 63 times 4, and we get 252.
Hope this helps!
