Traveling with the wind, Jerry takes 10 minutes to bicycle to a local library 2.5 km away. Coming back against the wind, it take
olganol [36]

7.5 km/h

Step-by-step explanation:

Let's assign the speed of Jerry in still air as <em>x </em> (in km/h)

Let's assign the speed of the wind as <em>y </em>(in km/h)

With the wind as Jerry’s back, he takes 10 minutes to get to the library. We can create the following equation. (<em>we are converting the minutes to hours by dividing by 60</em>);

2.5 / (x + y) = 10/60

10x + 10y = 150

x + y = 15

With the wind against Jerry, he takes 15 minutes from the library. We can create the following equation;

2.5 / (x-y) = 15/60

15x – 15y = 150

x – y = 10

We can now solve the simultaneous equation by subtraction;

x + y = 15

x – y = 10

2y = 5

y = 5/2 = 2.5

y = 2.5 km/h

x = 7.5 km/h

Write an equation in point-slope form of the line through point J(4,1) with slope -4.
Nimfa-mama [501]
Point slope form
y - y1 = m(x - x1)

Plug in the given
slope = -4
Point ( 4, 1)

y - 1 = -4(x - 4)
y - 1 = -4x +16
add 1 to both sides
y = -4x + 17

Hope this helps!

Find two numbers whose product is 42 and difference is 1.
Butoxors [25]
Okay, So We Need Two Numbers That Multiply To Get 42. Lets Look At All Of The Ways To Get 42.
1 * 42 
2 * 21
6 * 7
7 * 6 
21 * 2
42 * 1

So, 21 and 2 don't have a difference of one. 
42 and 1 don't have a difference of one. 

6 and 7 have a difference of one, which means your two mystery numbers are 6 and 7.
