The large triangle is isosceles, so that the two smaller triangles that appear inside the large one have bases of 12/2, or 6.
Let's see how x and y are related:
sin 60 degrees = opp/hyp = x/y = sqrt(3) / 2
and cos 60 degrees = adj/hyp = 1/2 = 6 / y. Then y = 12 (which should be no surprise, since the large triangle is equilateral).
Then: x/y = sqrt(3) / 2, or
x sqrt(3) x
---- = ----------- = ------ , so that 2x = 12sqrt(3), or x=6sqrt(3).
y 2 12
In summary,
x = 6√3
y=12
A statementent of the relationship and a function is that the numbers from the x-axis cannot be double number with another number heres an example.
For Example:
1 6
7 4
5 2
Ok for example the number seven can only be with only one of the numbers from the right side but the number from the right side can be with more than one number get it now?
I hope this helps you for your math class.
Hi there! :)
Answer:
(75x - 67y) - (47x + 15y)
Distribute the '-' sign with the terms inside of the parenthesis:
75x - 67y - (47x - (15y))
75x - 67y - 47x - 15y
Combine like terms:
28x - 82y
Distribute out the greatest common factor:
2(14x - 41y)
If f(x) = (5x + 1) /2
Ok, you need to find inverse function, here's how...
1. Change "f(x)" to y, to make the calculations easier. y = (5x + 1) /2 2. Switch x and y: x = (5y + 1) /2 3. Solve for y: x = (5y + 1) /22x = 5y + 12x - 1 = 5y(2x - 1) / 5 = y 4. Change "y" to f-1(x) (2x - 1) / 5 = f-1(x) Now, plug in 8 for x to get the answer: (2*8 - 1) / 5 = (16 - 1) / 5 = 15/5 = 3
Hope this helps :)
False I’m pretty sure hehe
