Solve the equation using inverse operations. Check your solutions. In your final answer, include all of your work.

REY [17]

Answer:

$x=\sqrt{10}$

Step-by-step explanation:

The given equation is :

$5-2x^2=-15$

We need to solve it using inverse operations.

Subtract 5 from both sides of the equation.

$5-2x^2-5=-15-5\\\\-2x^2=-20\\\\2x^2=20\\\\x^2=10\\\\x=\sqrt{10}$

So, the solution of the given equation is $x=\sqrt{10}$ .

The graph represents this system of equations y equals 4 - x y equals x - 2 what is the solution to the system of equations

babunello [35]

The solution to the system of equations is (3,1)

Step-by-step explanation:

The system of equations represented by graph are:

$y=4-x\\y=x-2$

Solving the system of equations

Let:

$y=4-x\,\,\,eq(1)\\y=x-2\,\,\,eq(2)$

Putting value of y from eq(2) into eq(1):

$x-2=4-x\\Simplifying:\\x+x=4+2\\2x=6\\x=6/2\\x=3$

So, Value of x = 3

Putting value of x into eq(2)

$y=x-2\\y=3-2\\y=1$

So, value of y= 1

So, The solution to the system of equations is (3,1)
