To more easily graph this, convert it to slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept):
x - y = 1
-y = -x + 1
y = x - 1
The slope is 1 and the y-intercept is -1. To graph this, plot the point (0, -1) and count 1 unit down and 1 unit to the right. Do this once more, connect the points, and you have your line.
Hope this helps.
To find the length of the hypotenuse we must use Pythagoras' Theorem: c^2 = a^2 + b^2, where c is the hypotenuse and a and b are side lengths
c^2 = a^2 + b^2
c^2 = 12^2 + 35^2
c^2 = 144 + 1225
c^2 = 1369
c = 37 cm
Since the side of the square frame is 15x, the area of the frame in whole would be:
(15x)² = 225x²
Now if we subtract out the circle mirror with a radius of 5x, we get:
225x² - πr²
225x² - π(5x)²
225x² - π25x²
We can factor out a 25x² and get:
25x² (9 - π)
Answer:
16
Step-by-step explanation:
There are 2 different ways to solve this
1) The bigger triangle is 4 times bigger than the smaller one
5 x 4 = 20
3 x 4 = 12
From this method you can see they all connect so you take the smaller triangles value of 4 and multiply it by 4
4 x 4 = 16
2) Pythagorean theorem and reorganizing the formula so that the a value is found
