Four times the difference of a number and seven is at least -52

Zina [86]

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

I hope that helps, and what you are looking for : )

A student claims that -4i is the only imaginary root of a quadratic polynomial equation that has real coefficients.

Nat2105 [25]

Answer:

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

$x^{2} + 16 = 0$

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

⇒ $x^{2} - (4i)^{2} = 0$

⇒ $x^{2} - (- 16) = 0$

⇒ $x^{2} + 16 = 0$ (Answer)
