Four times the difference of a number and seven is at least -52
4(m - 7 ) = - 52 =========> m = -6
Solve:
4(m - 7) = -52
We move all terms to the left:
4(m - 7) - (-52) = 0
We add all the numbers together, and all the variables
4(m - 7) + 52 = 0
We multiply parentheses
4m - 28 + 52 = 0
We add all the numbers together, and all the variables
4m + 24 = 0
We move all terms containing m to the left, all other terms to the right
4m = -24
m = -24 / 4
Answer ==========> m = -6

Answer:
If a quadratic equation has an imaginary root -4i, then its conjugate i.e. 4i will be the other root of the equation.

Step-by-step explanation:
a. The only imaginary root of a quadratic equation is -4i, this is not possible.
Because, if a quadratic equation has an imaginary root -4i, then it's conjugate i.e. 4i will be the other root of the equation.
b. So, the two roots of a quadratic equation are imaginary and they are 4i and -4i.
Therefore, the equation will be
(x - 4i)(x + 4i) = 0
