The smallest y-value is -3 when x=0
[-3,∞)
Hi,
8 Pckts each has 500 g weight .Total weight would be 8*500=4000g
and she arranged them into 3 boxes.
assume those three boxes are X,Y,Z first,second,thrid respectively.
X+Y+Z=4000g--------------------1
then according to the statement first box is twice heavy as second one
means X=2Y----------------2
and thrid box is 60g heavier than second box.
Z=Y+60--------------------3
put those values in to eq 1
2Y+Y+Z=4000
3Y+Y+60=4000
4Y=4000-60
4Y=3940
Y=985
second box weight is 985 gram
9514 1404 393
Answer:
7x^3 +11x^2 -5x -8
Step-by-step explanation:
Combine like terms.
(4x^3+6x^2+2x^2-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +2 +3)x^2 +(-5)x + (-3 -5)
= 7x^3 +11x^2 -5x -8
_____
Noting that the first expression contains two x^2 terms, we wonder if you actually want the sum ...
(4x^3+6x^2+2x-3) + (3x^3+3x^2-5x-5)
= (4 +3)x^3 +(6 +3)x^2 +(2 -5)x +(-3 -5)
= 7x^3 +9x^2 -3x -8

Answer:
$18.00
Step-by-step explanation:
Start by working out 10%, that's easy:
15 ÷ 10 = 1.5
That means a 10% tip would be $1.50, so a 20% tip would be twice that amount:
1.50 x 2 = 3
A 20% tip is $3.00, and added on to the original $15.00, the total is $18.00
