y = 2/7 x - 1/7
slope = 2/7
perpendicular lines, slope is opposite and reciprocal
so slope of new line = -7/2
passes through the point (9,-32)
slope-intercept form: y = mx + b
so
b = y - mx
b = -32 - (-7/2)(9)
b = -32 + 63/2
b = -1/2

equation in slope-intercept form:
y = -7/2 x - 1/2

Maureen walked 3 miles how many feet did she walk

Ostrovityanka [42]

Answer:

15,840 feet.

Step-by-step explanation:

We have been given that Maureen walked 3 miles. We are asked to convert the distance walked by Maureen in feet.

Since we know that 1 mile equals 5,280 feet, so to convert our given distance we will multiply 3 by 5,280.

$\text{Number of feet Maureen walked}=\text{3 miles}\times \frac{5,280\text{ feet}}{\text{Mile}}$

$\text{Number of feet Maureen walked}=3\times 5,280\text{ feet}$

$\text{Number of feet Maureen walked}=15,840\text{ feet}$

Therefore, Maureen walked 15,840 feet.
