You basically plug in the x in the equation, for example if x = 4 and the equation is y = 2x + 5 you plug in 4 and the equation becomes y = 2(4) + 5. you then multiply and get y=8+5. from here u just add it and u get ur answer

Answer:

0.0078125

Step-by-step explanation:

If the probability of flipping a fair coin (mentally) correctly for 1 row is 0.5, then the probability of flipping it correctly for 2 rows is

0.5 * 0.5 = 0.25

for 3 rows: 0.5*0.5*0.5 = 0.125

...

For 7 rows:

$0.5*0.5*0.5*0.5*0.5*0.5*0.5 = 0.5^7 = 0.0078125$

Given the equation:

Alisiya [41]

Answer:

x = 1 and x = $\frac{-4}{5}$

Step-by-step explanation:

In this equation, a=5, b=-1, c=-4.

Plug these into the quadratic formula:

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

Now, simplify the equations:

x = $\frac{1+\sqrt{81} }{10}$ = $\frac{1+9}{10}$ = $\frac{10}{10}$ = 1

and

x = $\frac{1-\sqrt{81} }{10}$ = $\frac{1-9}{10}$ = $\frac{-8}{10}$ = $\frac{-4}{5}$
