Answer:

A) y = x^2 -1

B) -y = 2x^2 +1 We multiply B) by -1

B) y = -2x^2 -1

We can then say x^2 -1 = -2x^2 -1

3 x^2 = 0

x = 0

************* Double-Check: ******************

Equation A) y = -1 and

Equation B) y = -1

Which ordered pairs are in the solution set of the system of linear inequalities?

Elanso [62]

Answer:

The ordered pairs (5 , -2) , (3 , 1) , (4 , 2) are in the set of the solution ⇒

3rd answer

Step-by-step explanation:

- The first line has negative slope and passing through points (0 , 0)

and (4 , -2)

∵ $y>\frac{-1}{2}x$

- The second line has positive slope and passing through points (-2 , 0)

and (2 , 2)

∵ $y$

- Look to the attached figure to see the common part of the solutions

- The red shaded represents the inequality $y>\frac{-1}{2}x$

- The blue shaded represents the inequality $y$

- The shaded part with two colors represents the common solutions

of the two inequalities

- Lets find the ordered pairs which are in the solution set of the system

of linear inequalities

- Points (-4 , 2) , (-3 , 1) , (4 , -3) lies out the common shaded

- Points (5 , -2) , (3 , 1) , (3 , -1) , (4 , 2)

∵ Point (5 , -2) lies in the common shaded part

∵ Point (3 , 1) lies in the common shaded part

∵ Point (4 , 2) lies in the common shaded part

∴ The ordered pairs (5 , -2) , (3 , 1) , (4 , 2) are in the set of the

solution

Determine if the equations are intersecting, parallel, or coincident.

aleksandrvk [35]

Since bx does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting bx from both sides.
-ay=-bx+2 
ax+by=3 

Divide each term in the equation by -1a. 
y=(bx-2)/(a) 
ax+by=3 

Divide each term in the numerator by the denominator. 
y=(bx)/(a)-(2)/(a) 
ax+by=3 

The equation is not linear, so the slope does not exist. 
No slope can be found. 
ax+by=3 

Since ax does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting ax from both sides. 
No slope can be found. 
by=-ax+3 

Remove the common factors that were cancelled out. 
No slope can be found. 
y=-(ax)/(b)+(3)/(b) 

Divide each term in the equation by b. 
No slope can be found. 
y=(-ax+3)/(b) 

Divide each term in the numerator by the denominator. 
No slope can be found. 
y=-(ax)/(b)+(3)/(b) 

The equation is not linear, so the slope does not exist. 
No slope can be found. 
No slope can be found. 

Compare the slopes (m) of the two equations. 
m1=, m2= 

The equations are parallel because the slopes of the two lines are equal.
