so we know that the size of the triangle is decreasing witch means that the scale factor is going to be a fraction. to find this fraction you are going to divide the smaller side by the corisponding longer side.
12/72= 1/6
the correct answer is c 1/6
Step-by-step explanation:
y-5 = 2(x-3)
y-5 = 2x -6
y = 2x -1
Step-by-step explanation:
Let the number be x, then
![\frac{x}{2 + 7} \\ \frac{x}{9}](https://tex.z-dn.net/?f=%20%5Cfrac%7Bx%7D%7B2%20%2B%207%7D%20%20%5C%5C%20%20%5Cfrac%7Bx%7D%7B9%7D%20)
If it is a rhombus then you know each side is the same length, so only have to work out one side. To do this you have to use Pythagoras' theorem (a^2 + b^2 = c^2)
So take two sets of coordinates, for example, (0,3) and (5,3), a and b represent the height difference and the length difference. Therefore (5-0)^2 + (3-3)^2 = c^2
c^2 = 25
c = 5 , which would be the side of the rhombus
Answer:
A and D are the true number sentences
