Answer:

Step-by-step explanation:

Slope formula=

$\frac{y2-x2}{y1-x1}$

so the slope is

$\frac{-4-16}{2-6}$

$\frac{-20}{-4}$

or $5$

so the slope is 5

Hope this helps ;D

Y =9x+13 y =2x+48 Can you find the x and the y

Digiron [165]

9x+13=2x+48
-2x -2x
7x+13=48
-13 -13
7x=35
/7 /7
x=5

y=9(5)+13
y=45+13
y=58

Brian has 16 yards of chain measured and cut at the. Hardware store. The chain will cost him 47.52$ how much is that per food? _

mojhsa [17]

3 feet= 1 yard

16*3= 48 feet.

47.52/48= 0.99

It will cost Brian $0.99 per foot.

Find the unit rate.

49.50/50= 0.99

No, it wouldn't. It would be the same price

0.99=0.99 It doesn't matter which one Brian chose. 

I hope this helps!

Answer:

d = 5/6t

Step-by-step explanation:

5 stories every 6 seconds

at 12 seconds, it would have travelled 10 seconds.

using this 2 data in this formula

(y-y1)/(x-x1) = (y2-y1)/(x2-x1)

Note : d = y, t = x;

d1 = 5, t1 = 6, d2 = 10, t2 = 12

we have

(d - 5)/(t-6) = (10-5)/(12-6)

(d - 5)/(t-6) = 5/6

d = 5/6(t-6) + 5

d = 5/6t -5+5

d = 5/6t

The volume

Sedaia [141]

$\bf \begin{array}{cccccclllll}
\textit{something}&&\textit{varies directly to}&&\textit{something else}\\ \quad \\
\textit{something}&=&{{ \textit{some value}}}&\cdot &\textit{something else}\\ \quad \\
y&=&{{ k}}&\cdot&x
&& y={{ k }}x
\end{array}\\ \quad \\
$

and also

$\bf \begin{array}{llllll}
\textit{something}&&\textit{varies inversely to}&\textit{something else}\\ \quad \\
\textit{something}&=&\cfrac{{{\textit{some value}}}}{}&\cfrac{}{\textit{something else}}\\ \quad \\
y&=&\cfrac{{{\textit{k}}}}{}&\cfrac{}{x}
&&y=\cfrac{{{ k}}}{x}
\end{array}
$

now, we know that V varies directly to T and inversely to P simultaneously
thus $\bf V=T\cdot \cfrac{k}{P}$

so $\bf V=T\cdot \cfrac{k}{P}\qquad 
\begin{cases}
V=42\\
T=84\\
P=8
\end{cases}\implies 42=\cfrac{84k}{8}\implies 4=k
\\\\\\
V=\cfrac{4T}{P}\qquad now\quad 
\begin{cases}
V=74\\
P=10
\end{cases}\implies 74=\cfrac{4T}{10}\implies 185=T$
