Which expression is equivalent to 1/3b - 7?

olga55 [171]

Answer:

$\dfrac{1}{3}(b-21)$

Step-by-step explanation:

We need to find an equivalent expression for $\dfrac{1}{3}b-7$

The denominator of first fraction is 3 and that of other is 1.

$\dfrac{1}{3}b-7\\\\=\dfrac{b-21}{3}$

$=\dfrac{1}{3}(b-21)$

Hence, the equivalent expression is $\dfrac{1}{3}(b-21)$ .

What are the zeros of the quadratic function f(x) = 6x^2 + 12x – 7?

irinina [24]

<span>6x^2 + 12x – 7 = 0

Use the quadratic formula:

$x= \frac{-b +/- \sqrt{b^2 -4ac} }{2a}$

$\frac{-12+/- \sqrt{ 12^{2} -4(6)(-7)} }{12} = \frac{-12+/-17.66}{12}$

x = 0.47 and x = -2.47
