Answer:

m > 4

Step-by-step explanation:

5m - 8 > 12

Add 8 to each side

5m - 8+8 > 12+8

5m > 20

Divide by 5

5m/5 > 20/5

m > 4

Which equation justifies why 93-3√9?

Simora [160]

Considering the conversion from exponent to radical, the equation that justifies why the expression $9^{\frac{1}{3}} = \sqrt[3]{9}$ is correct is.

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

<h3>How is the conversion from exponent to radical realized?</h3>

The conversion of rational exponents to radical notation is modeled by:

$a^{\frac{n}{m}} = \sqrt[m]{a^n}$

In this problem, the expression is:

$9^{\frac{1}{3}} = \sqrt[3]{9}$

And the equation that shows that this is correct is:

$(9^{\frac{1}{3}})^{3} = 9^{\frac{3}{3}} = 9$

Calculate.<br> 1) 4 x (3 divided by 8 + 1)

grin007 [14]

4(3/(8+1) = 4(3/9) = 12/9 = 4/3

4((3/8)+1) = 4(11/8) = 44/8 = 11/2

just depends on which way the equation is written

How to solve this equation equal to zero

hjlf

3x² -16x-12 =0

We can solve this equation using formula.

a=3, b=-16, c=-12

$x= \frac{-b+/- \sqrt{b^{2} -4ac} }{2a} 
\\ \\ x= \frac{16+/- \sqrt{16^{2}+4*3*12} }{2*3} = \frac{16+/- \sqrt{400} }{6} = \frac{16+/-20}{6} 
\\ \\ x_{1}= \frac{16+20}{6} =6
\\ \\x_{2}= \frac{16-20}{6} =- \frac{4}{6} = -\frac{2}{3}$
