Give the values of a, b, and c needed to write the equation's general form. 1/4x^2 + 5 = 0

1. A = 1/4; B = 5; C = 0
2. A = 1; B = 0; C = 20
3. A = 1; B = 0; C = -5

I worked it out and got A= 1; B = 0; C = 20. I'm not really sure if I'm correct or not, please confirm for me, thank you!

What are the solutions of the system? y = x^2 + 2x +3y = 4x - 2a. (-1, -6) and (-3, -14)b. (-1, 10) and (3, -6)c. no solutiond. (-1, -6) and (3, 10)

Ascientist has 50 grams of a radioactive element. the amount of radioactive element remaining after t days can be determined using the equation (1) after two days the scientist receives a second shipment of 50 grams of the same element. the equation used to represent the amount of shipment 2 remaining after t days is 10) - 50 which of the following is an equivalent form of the expression for the amount remaining in shipment 2? what’s the answer?

Write a description of each inequality. 1. -5a + 3 > 1 2. 27 - 2b < -6 (this < has a _ under it) 3. 1/2 (c + 1) > 5 (this > has a _ under it)
