Answer:
x = -2 (multiplicity 2).
Step-by-step explanation:
3x^2+12x+12 = 0
3(x^2 + 4x + 4) = 0
3(x + 2)(x + 2) = 0
x = -2 (multiplicity 2).
2 roots - both equal.
To find this answer, first subtract 1,500 from the amount your class raises (16, 600) so you are just left with the 'leftover' money for students to board.
16600-1500= 15100.
Then, divide 15100 into 367 to find out how many can go.
15100/367= 41.1444. Round down to 41.
41 students can attend, and there will be a bit of leftover money. (if you want to figure out how much is left over, multiply 41 by 367, and then subtract 15100 by the product)
Answer:
solution
is
you minus smallest x(you minus because the opposite of positive ia negative)
so you do x-x=0 and 4-x=3
so 2y/2. and 3÷2
so x is 1.5
for the 2nd question 3x -2y= -12
you do add 2y on both sides
so -2y+2y =0 and -12 +2y= -10 y
so 3x/3 and -10y /3
x= - 3.3333333333
