Answer:
slope of the line is 50
Step-by-step explanation:
The slope of a line (gradient) is determined by the rise/run so
(y2 - y1) / (x2 - x1)
We simply substitute in our coordinates and solve. So:
(4000 - 3000) / (60 - 40)
= 1000 / 20
= 100/2 = 50
Gradient is 50
Answer:
piex
Step-by-step explanation:
the circumference of a circle is pie times the diameter of the circle.
Step-by-step explanation:
Ooh ape--x I just did this a few weeks ago. To find the inverse, you need to reverse the process. So, instead of adding subtract, and instead of dividing, multiply. It's so easy once you get it.
Start by substituting y for f(x), and then switching x and y, and once you've solved for y I believe, you write f^-1(x) in y's place.
