90,000 becuase 63,824 is rounded down to 60,000 and 29,452 is rounded up to 30,000. 60,000+30,000 is 90,000

Q8 Q3.) Solve the system by the substitution method.
inn [45]
Recall that (x+y)^2=x^2+2xy+y^2. So we can add twice the first equation to the second one to get

x^2+y^2+2xy=10+2\cdot3\iff(x+y)^2=16\implies x+y=\pm4

Since xy=3, we have y=\dfrac3x (x\neq0) so

x+y=x+\dfrac3x=\pm4\implies x^2\mp4x+3=0

If x+y=4, then

x^2-4x+3=(x-3)(x-1)=0\implies x=3,x=1\implies y=1,y=3

If x+y=-4, then

x^2+4x+3=(x+1)(x+3)=0\implies x=-1,x=-3\implies y=-3,y=-1

So the solution set is

(x,y)\in\{(-3,1),(1,3),(-1,-3),(-3,-1)\}

What is the answer to this math equation(x+5)(x²-3x)​
Nikolay [14]

Answer:

x=-5\\x=0\\x=3

Step-by-step explanation:

I assume your equation to solve is

(x+5)(x^2-3x)=0

When we have a product of two factors equal to zero,

A\cdot B = 0

The solution is either A = 0 or B = 0.

In this case, this means that we can break the equation into two equations:

x+5=0\\x^2-3x=0

Solving the first one, we get:

x+5=0 \rightarrow x = -5

For the second one, we rewrite it as:

x^2-3x=0\\x(x-3)=0

And we see that this equation has two solutions:

x=0\\x=3

Therefore, the three solutions are:

x=-5\\x=0\\x=3

Suppose you are doing a puzzle. After 10 minutes, you have 275 pieces placed, and after 22 minutes, you have 395 pieces placed.
LenKa [72]

Answer:

600 pieces

Step-by-step explanation:

pieces/ time(min) = (395-275) / (22-10) = 120/ 12 = 10

10= x (pieces) / 60(min) => x = 60×10 => x = 600 pieces
