5x + 2y = 30
x + y = 8 <==== multiply by -2
--------------
5x + 2y = 30
-2x - 2y = -16 (result of multiplying by -2)
-------------add
3x = 14....u see how multiplying by -2 will eliminate the y's

Real numbers x and y satisfy x + xy^2 = 250y, x - xy^2 = -240y. Enter all possible values of x, separated by commas.

agasfer [191]

Answer:

-35,35,0

Step-by-step explanation:

Let's organise our information :

x+xy²=250y
x-xy²= -240y

Now let's add them together :

x+xy²+x-xy²=250y-240y
2x=10y
x=5y ⇒ y= x/5

Let's replace y by x/5 in the first equation :

x+x*(x/5)²=250*(x/5)
x+ (x∧3)/25 = 50x
49x-(x∧3)/25=0
x(49-(x²/25))=0
x=0 or 49-(x²/25)=0
x=0 or 49= x²/25
x=0 or x²=1225
x=0 or x= $\sqrt{1225}$ or x= - $\sqrt{1225\\}$
x=0 or x=35 or x= -35

so x=[0,35,(-35)]

Mr. duc asked to set up 450 chairs in a large hall. Perry puts 20 chairs in each row. He has already set up 15 rows of chairs

Each row consists of 20 chairs

He already set up 15 rows

So number of chairs he already set up = chairs in each row * number of rows

20 * 15 = 300

So , he already set up 300 chairs

Total chairs to set up is 450

Remaining chairs to set up = 450 - 300 = 150

So, 150 more chairs to set up
