The expression 53.7124×103 as a single number

riadik2000 [5.3K]

Answer:

53712.4

Step-by-step explanation:

$53.7124 * 10^{3}$ This is the scientific notation, and since we do not have a negative exponent, we can assume that the decimal is going to move to the right, because when it's negative, the decimal will move to the left, making a smaller number.

So, when we move the decimal 3 times to the right, we find it sitting at 53712.4

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

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