Answer:
A person in a group where 5 people are sharing 3 small bags of snickers
Step-by-step explanation:
Let the number of calories in one bag of snickers =x
Number of calories in 3 small bags of snickers =3x
- If 5 people share 3 small bags of snickers, 1 person's share
Number of calories in 2 small bags of snickers =2x
- If 7 people share 2 small bags of snickers, 1 person's share
We then compare the two.
Let x=1
Therefore, a person in a group where 5 people are sharing 3 small bags of snickers gets more calories.

Step-by-step explanation:
.
m is the slope of the line. To find it we can do which is the difference between the y-coordinates divided by the difference between the x-coordinates.
So: . Now we have the slope, let's input a set of coordinates into the equation so that we can find the constant
.
- Re-arranging to get b
Now re-write the equation as we have the constants.
Answer:
a) f(x) tends to minus infinity
b) (0,768) is the y-intercept, (4,0) and (-3,0) are the x-intercepts.
Step-by-step explanation:
Our function is a polynomial of degree 4.
a) The monomial with highest degree determines the behavior of f(x) when x tends to infinity and when x tends to -infinity. This monomial is -4x⁴. Without expanding completely, (x-4)³ has x³ as a summand, which multiplies with -4x from the first factor, to give -4x⁴. When x goes to infinity (or minus infinitive), x²=(x²)² is positive (nonzero squares are always positive) thus -4x² is negative, and f(x) tends to minus infinity.
b). To find the y-intercept, we compute (0,f(0)). Since f(0)=-4(3)(-4)³=768, then (0,768) is the point of the y-intercept.
For the x-intercept, solve f(x)=0. f(x)=0 has the solutions x=-3 and x=4. In this case, the x-intercept is in both x=0 and x=4. Then (-3,0) and (4,0) are x-intercepts.
