Consider the following system of equations:

Delicious77 [7]

Answer:

The system has infinitely solutions

Step-by-step explanation:

we have

$-\frac{1}{3}x^{2}=-\frac{5}{6}+\frac{1}{3}y^{2}$

$\frac{1}{3}x^{2}+\frac{1}{3}y^{2}=\frac{5}{6}$

Multiply by 3 both sides

$x^{2}+y^{2}=\frac{5}{2}$ ----> equation A

The equation A is a circle centered at origin with radius $r=\sqrt{5/2}\ units$

and

$5y^{2} =\frac{25}{2}-5x^{2}$

$5x^{2}+5y^{2} =\frac{25}{2}$

Divide by 5 both sides

$x^{2}+y^{2} =\frac{5}{2}$ ----> equation B

The equation B is a circle centered at origin with radius $r=\sqrt{5/2}\ units$

Equation A and Equation B are the same

Therefore

The system has infinitely solutions

Question #3: Complete the statement below to show the correct value of 100%. Part A: The expression 100 3 = 10 because 100 = 102

BigorU [14]

Answer:

Step-by-step explanation:

Part A.

Expression $(100)^{\frac{1}{2}}$ = 10

Because 100 = $(10)^{2}$ and $[(10)^2]^{\frac{1}{2}}=10^1=10$

[Since, $(a^{2})^{\frac{1}{2}}=a^{2\times \frac{1}{2}}=a^1$ ]

Part B.

When simplified, the answer is RATIONAL.

[Since, 10 can be written as $\frac{10}{1}$ ]

What is the percent of change from 75 to 14 rounded to nearest percent??

zhuklara [117]

- 81 %

Step-by-step explanation:

To find the percentage change;

([Current – Initial] / Initial) * 100

([14 - 75] / 75) * 100

(-61 / 75) * 100

(-0.81333) * 100

= - 81.3333 %

To the nearest percentage;

= - 81 %
