Determine the slope of a line that passes through A(-4, 7) and B(6,3)

Helga [31]

Answer:

$m=\frac{-2}{5}$

Step-by-step explanation:

Use the formula:

$m=\frac{y_2-y_1}{x_2-x_1}$

Plug in the numbers (coordinates) given, like so:

$m=\frac{3-7}{6+4}$

$m=\frac{-4}{10}$

Simplify:

$m=\frac{-2}{5}$

There are 250 bricks used to build a wall 20 feet high.How many bricks will be used to buld a wall that is 30 fet high

Dmitry_Shevchenko [17]

Answer: 375

Step-by-step explanation:

Since we are given the information that there are 250 bricks used to build a wall 20 feet high, the number of brick used per feet will be:

= 250/20

= 12.5 bricks per feet.

Therefore, the number of bricks that will be used to buld a wall that is 30 fet high will be:

= 12.5 × 30

= 375 bricks.

Therefore, 375 bricks would be used.

4)^-5 write in a simplified fraction

erastova [34]

$\bf 4^{-5}?\qquad \textit{well, bear in mind that}\\
----------------------------\\
a^{-{ n}} \implies \cfrac{1}{a^{ n}}\qquad \qquad

\cfrac{1}{a^{ n}}\implies a^{-{ n}}
\\ \quad \\
% negative exponential denominator
a^{{ n}} \implies \cfrac{1}{a^{- n}}
\qquad \qquad 

\cfrac{1}{a^{- n}}\implies \cfrac{1}{\frac{1}{a^{ n}}}\implies a^{{ n}}\\
----------------------------\\
thus\implies 4^{-5}\implies \cfrac{1}{4^{+5}}\implies \cfrac{1}{4^5}\implies \cfrac{1}{1024}$
