4x+16=-2
Subtract 16 from both sides
4x=-18
Divide both sides by 4
x=-18/4
x= -9/2
Final answer: x=-9/2

The answer it negative 450
Answer:
(0,0) and r=3
Step-by-step explanation:
To find the radius and center rewrite the equation in vertex form .
First move x and y to the other side so they have positive signs. Then move 9 across to the other side too.
Here you can see there is no h or k meaning h=0 and k=0. The radius is the square root of 9 which is 3.
One pound is equal to 16 ounces. so to do this you would need to multiply 5 by 16 to get 80 ounces total. Then you would subtract the 12 from the 80 since she gave it away and it isn't included in the bags that she is giving out.this leaves you with 68 ounces. Finally, you would divide 68 by 4 to get 17. She made a total of 17 bags of trail mix.
