Answer:

29.25 miles

Step-by-step explanation:

We can use a ratio to solve

1 inch            2.5 inches

------------  = ----------------

11.7 miles         x miles

Using cross products

1 * x = 11.7 * 2.5

x =29.25

When asked to write a point slope equation for a line passing through the points (-4,-7) and (3,2) a student wrote y-2=-9/7(x-3)
AleksAgata [21]
First let's find the slope
Slope formula: 
\frac{y_2-y_1}{x_2-x_1} =slope
Given the two coordinates: 
(-4,-7) (3,2) 
 x1,y1  x2,y2

Plug these numbers into the formula
\frac{2-(-7)}{3-(-4)} = \frac{9}{7}
In this case the mistake that was made was that the student wrote the slope negative instead of positive
Final answer: 
<span>y-2=9/7(x-3)</span>

Item 6 Your city is represented in a coordinate plane where each unit represents 1 kilometer. The library is at (−3, −3), the po
Snezhnost [94]

We know, shortest distance between two points (x_1,y_1) and (x_2,y_2) is :

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

So, distance between house and library is :

d_1=\sqrt{(-5-(-3))^2+(2-(-3))^2}\\\\d_1=5.39\ km

Distance between library and post office :

D=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\D=\sqrt{(-3-2)^2+(-3-2)^2}\\\\D=7.07\ km

Distance between post office and house :

D=\sqrt{(2-(-5)^2)+(2-2)^2}\\\\D=7\ km

Therefore, minimum distance that you can ride your bike is (5.39+7.07+7) km = 19.46  km.

Hence, this is the required solution.
