Help please (i pressed 0.09 by mistake)
Alja [10]

Answer:

The answer should be .25

Step-by-step explanation:

The answer should be .25 because:

- there are 4 places you can score and since you want it to land on 5 and there is only one 5 it counts as a 1

- the since there are 4 in total and you want to land on 1 you get 1/4 the number one standing for there only being one 5 and the 4 standing for the number of places to land on.

-then you convert the 1/4 into a decimal which makes .25

Find the slope of the line that is parallel and perpendicular <br><br> -7x-2y=4
Rus_ich [418]

\bf -7x-2y=4\implies -2y=7x+4\implies y=\cfrac{7x+4}{-2}\implies y=\cfrac{7x}{-2}+\cfrac{4}{-2} \\\\\\ y=\stackrel{\stackrel{m}{\downarrow }}{-\cfrac{7}{2}} x-2\qquad \impliedby \begin{array}{|c|ll} \cline{1-1} slope-intercept~form\\ \cline{1-1} \\ y=\underset{y-intercept}{\stackrel{slope\qquad }{\stackrel{\downarrow }{m}x+\underset{\uparrow }{b}}} \\\\ \cline{1-1} \end{array} \\\\[-0.35em] ~\dotfill

\bf \stackrel{\textit{perpendicular lines have \underline{negative reciprocal} slopes}} {\stackrel{slope}{-\cfrac{7}{2}}\qquad \qquad \qquad \stackrel{reciprocal}{-\cfrac{2}{7}}\qquad \stackrel{negative~reciprocal}{\cfrac{2}{7}}}

now, what's the slope of a line parallel to that one above?  well, parallel lines have exactly the same slope.

Julia asked to evaluate the expression four to the power of -3 before she can join her classmates outside. She decides to use th
vesna_86 [32]

Negative exponents work like this:

a^{-b}=\dfrac{1}{a^b}

So, you have

4^{-3}=\dfrac{1}{4^3}=\dfrac{1}{64}

This number is less than 1, so she will play tennis.

What is the simplified form of the expression? (picture attached)
LenaWriter [7]
1- Let's solve the numerator Inside the bracket m⁻¹.m⁵ =m⁽⁻¹⁺⁵⁾ =m⁽⁴⁾

2- numerator/denominator = m⁽⁴⁾ / m⁻² = m⁽⁴⁾⁻⁽⁻²⁾  =m⁶

3- Now let' include it in the parenthesis:[ m⁶]⁻³ =m⁻¹⁸ =1/m¹⁸<u />
