the system of equations is equal at approximately
(1.5,1.2)
(-1.5,-1.2)
(1.5,-1.2)
(-1.5,1.2)

option A

(1.5,1.2)

Step-by-step explanation:

Given in the question two equations

Equation 1

y = √x

Equation 2

y = x²- 1

Equate both equations

√x = x²- 1

1 method by plotting graph

We can see from the graph that both meets when x =  1.5 and y = 1.2

2 method

we can plug the options given one by one to see which points satisfy

one thing we know is that x ≠ any negative value since

y = √x and square root of negative value is not possible

so option b and c are rejected

  option A

√1.5 = y = 1.2

1.5²- 1 = y = 1.2

Chope this have a nice day btw the other person deserves brainlest

Planet earth has a mass of 5.9726x10²⁴ kg.then: 5.9726x10²⁴ kg=100% of the total earth mass.if the water´s mass=5x10-4 % of the total mass, we can solve this problem by the rule of three.5.9726x10²⁴ %*10⁻⁴ %x=(5.9726x10²³ kg)(5*10⁻⁴  %) / 100 %=2.9863x10¹⁹ kganswer:   the mass of the planet´s water would be   2.9863 x 10¹⁹ kg.
