13. Solve 5x² - 6x + 1 = 0 using the quadratic formula.<br><br><br> please help me and show work

yaroslaw [1]

Answer: x= 1, $\frac{1}{5\\}$

Step-by-step explanation:

The quadratic equation is

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

and

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

So we just need to sub in the proper numbers from the equation given, in this case, it would result in

$x=\frac{6+\sqrt{(-6)^{2}-4(5)(1) } }{2(5)}$

and

$x=\frac{6-\sqrt{(-6)^{2}-4(5)(1) } }{2(5)}$

Once we get this we can either manually simplify or use a calculator, using a calculator would result in the answers

x= 1, $\frac{1}{5\\}$

If (6^2)^x =1 what is the value of x

masya89 [10]

Answer:

x = 0

Step-by-step explanation:

Rewrite (6^2)^x =1 as 6^(2x) = 1.

Next, take the logarithm (common or natural) of both sides, obtaining

2x log 6 = log 1

2x log 6 = 0

Then x = 0.

Note that (6^2)^0 = 1, since any positive number raised to the prower 0 is 1.

-4d - 5 = -1 answer for me pls

PolarNik [594]

$\\ \sf\longmapsto -4d-5=-1$

Cancel - from both sides

$\\ \sf\longmapsto -(4d+5)=-(1)$

$\\ \sf\longmapsto 4d+5=1$

$\\ \sf\longmapsto 4d=1-5$

$\\ \sf\longmapsto 4d=-4$

$\\ \sf\longmapsto d=\dfrac{-4}{4}$

$\\ \sf\longmapsto d=-1$
