1 1/4mi = ft, can someone explain this to me
skelet666 [1.2K]
First off, we'll convert the mixed fraction to "improper" and check about, keeping in mind that, there are 5280 feet in 1mile.

\bf \stackrel{mixed}{1\frac{1}{4}~mi}\implies \cfrac{1\cdot 4+1}{4}\implies \stackrel{improper}{\cfrac{5}{4}~mi}\\\\
-------------------------------

\bf \begin{array}{ccll}
feet&miles\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
5280&1\\
f&\frac{5}{4}
\end{array}\implies \cfrac{5280}{f}=\cfrac{1}{\quad \frac{5}{4}\quad }\implies \cfrac{5280}{f}=\cfrac{\frac{1}{1}}{\quad \frac{5}{4}\quad }
\\\\\\
\cfrac{5280}{f}=\cfrac{1}{1}\cdot \cfrac{4}{5}\implies \cfrac{5280}{f}=\cfrac{4}{5}\implies \cfrac{5280\cdot 5}{4}=f\implies 6600=f

Someone answer the whole thing fast plz
Brilliant_brown [7]

Answer:

y = 2x + 54

Step-by-step explanation:

slope of equation:

(y2-y1)/(x2-x1)

= (72-58)/(9-2)

= 14/7

= 2

y = 2x + b

58 = 2(2) + b

58 = 4 + b

b = 54

Write the equation of the line in y=mx+b that passes through the points (5,10) and (6,12)
Damm [24]

Answer:

y = 2x + 0 or y = 2x

Step-by-step explanation:

use slope-intercept form \frac{y2 - y1}{x2 - x1}

12 - 10 = 2

6 - 5 = 1

m value = 2/1 = 2

y=2x+b

to find b plug one of the points in for x and y

Example: 10 = 2(5) + b

solve equation

10 = 10 + b

subtract 10 from both sides

0 = b

Equation of line equals y=2x+0 or simply just y=2x
