y = -4x
y = mx+b
b = 0
m = -4
here are some basic directions:
1. mark the point (0, 0) on the coordinate plane since b, aka the x intercept (where the line intersects with the x axis)
2. mark another point (1, -4) on the coordinate plane since we have defined a hawt slope ykyk
3. use the two points to guide ur ruler and draw a line idk how to describe it but yeah <3
Since the square root of 13 is something really weird (3.6055 something) and does not have a clear end or repeats, it is irrational. Solve for the number before assuming anything
<span>If you put the 9cm and 2cm rods together end-on-end, the new length is 11cm. Now if you repeat this with the 7cm and 5cm rods that new length is 12cm, so the difference between the two is now 1 cm. It does not seem very practical to walk around measuring items using the rods like this, so you could then make a small rod or use a strip of paper equal to the difference (1cm) as a standard measuring tool.</span>
He/She's wrong.
Area=pi*r^2
So 1808.64/3.14=576
Then the square root of 576 is 24
The answer is 24...
you got a 87.5% B
(divide what you got by how many points possible)
hope that helps :)
