Y= - x2 + 1 and y = x2. at which approximate points are the two equations equal?

see explanation

Step-by-step explanation:

given the 2 equations

y = - x² + 1 → (1)

y = x² → (2)

Substitute y = x² into (1)

x² = - x² + 1 ( add x² to both sides )

2x² = 1 ( divide both sides by 2 )

x² = ( take the square root of both sides )

x = ± = ±

Substitute these values into (2) for corresponding values of y

x = ⇒ y = ()² =

x = - ⇒ y = (- )² =

The points are ( ± , )

(–0.708, 0.50) and (0.708, 0.50)

Step-by-step explanation:

We are given the following two equation and have to determine the approximate points at which these equation are equal:

and

I have graphed these two equations as you can see below.

Here, points of intersection will be the solutions to a system of equation.

From the graph, I can say the point is about (–0.708, 0.50) and the other point where the two equations meet is nearly (0.708, 0.50).

So my approximate points are (–0.708, 0.50) and (0.708, 0.50).

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.

the 3rd on is correct
