Answer with explanation:

 The given function is

h(x)=3 x²-------(1)

We have to find those ordered pairs ,(1, 3) ,(−1, −3) ,(−1, 3) ,(1, −3) which satisfy the given function.

Substituting , different value of x,in equation 1 , to find correct ordered pairs.

1.

h(1)=3 × 1²=3×1=3

Ordered pair, (1,3) satisfy the given function.

2.

h(-1)=3 × (-1)²

      =3 × 1

     =3

Ordered pair, (-1,3) satisfy the given function.

Option A →(1,3) and C,→ (-1,3)

My house was very far out, hidden behind trees, and darkness was around me. Ahhh! The sound was repeating again and again so I decided to rush over to my phone to call the police. but then I realized that was just not any sound, but it was a cry for help. The police said they will send over a rescue worker to help me, to help them, whoever it is.

Help me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
ahrayia [7]

Answer:

9. x=-6, y=0

10. x=-9, y=-10

11. x=3, y=-1

Step-by-step explanation:

2x-9y=-12\\3x+18y=-18

Multiply the first equation by 2.

4x-18y=-24\\3x+18y=-18

Add the equations.

7x=-42

x=-6

We figured out x now we have to figure out y. To figure out y plug in x into any equation.

2(-6)-9y=-12

-12-9y=-12

-9y=0

y=0

Your answer is x = -6 and y = 0 for number nine.

6x+3y=24\\2x+3y=-12

Change the signs of the second equation becuase 3y and 3y are both positive. We need one of them to be negative.

6x+3y=24\\-2x-3y=12

Add them.

4x = 36

x=9

Now we have to figure out y.

2(9)+3y=-12

18+3y=-12

3y=-30

y=-10

x=-9 and y=-10 is your answer to number ten.

10x+5y=25\\-7x-3y=-18

30x+15y=75\\-35x-15y=-90

-5x=-15

x=3

-7(3)-3y=-18

-21-3y=-18

-3y=3

y=-1

x=3 and y=-1 is the answer to number eleven. I hope this helps! Let me know if I got anything wrong.
