Answer:
if you need the compound equality it is 2800 ≤ 850 + 12m ≤ 4500
Step-by-step explanation:
m= minutes 2800 is the minimum 4500 is the maximum 850 is from the people already in the park and 12m came from the people coming in per minute so i multiplied the 12 by m
Subsitte
y=6-x and y=x-2
both equal y so set equal;
6-x=y=x-2
6-x=x-2
add x both sides and addd 2
8=2x
divide 2
4=x
sub back
y=6-x
y=6-4
y=2
(x,y)
(4,2)
answer is C
The winner of an election is voted for by the majority of people. If there are two things being voted for, veggie pizza and chicken, and pizza earns 36% of the vote, then chicken must earn 64% of the vote because 36 and 64 add to 100.
Therefore, the chicken would win the election and be on the lunch menu.

Answer:
3 grams
Step-by-step explanation:
We are going to take the mass of a bunch of little strips below the triangle "roof." To do this, we must figure out what formula for the mass we'll use, in this case, we'll use:
Mass of strip = denisty * area = (1+x)*y*deltax grams
now, because the "roof" of the triangle contains two different integrals (it completely changes direction), we will use TWO integrals!
**pretend ∈ is the sum symbol
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral -1 to 0 of (1+x)*3*(x+1) = 3 * integral -1 to 0 of (x^2 + 2x + 1) = 3 * 1/3 = 1
Mass of left part = lim x->0 ∈ (1+x)*y*deltax = inegral 0 to 1 of (1+x)*3*(-x+1) = 3 * integral 0 to 1 of (-x^2 + 1) = 3 * 2/3 = 2
Total mass = mass left + mass right = 1 + 2 = 3 grams
