Answer:
x=5
Step-by-step explanation:
18x-11x-35=0
7x-35=0
7x=35
x=5
7.) the equation of the circle is
(x - 3)^2 + (y - 4)^2 = 25
If you substitute the point in you get
(6-3)^2 + (8-4)^2 = 25
3^2 + 4^2 = 25
9 + 16 = 25
25 = 25
Both sides of the equation are the same so it proves it lies on the circle
8.) you add the x coordinates together and divide by 2
7 + 4 = 11
11/2 = 5.5
You use +7 because you need to find the midpoint.
You then add 5.5 to - 7 or - 5.5 from 4
-7 + 5.5 = - 1.5
You do the same for y coordinates
6+5 = 11
11/2 = 5.5
6-5.5 = 0.5
So the coordinates of Rachel's house are
(-1.5, 0.5)
- 10, you go down 4 - this is shown because to get from two to 10 in two, you have to go 2+4=6+4=10
Edging is 18.84m. to find the edging you must do the radis times 2, then that answer by pi (3.14). So you do 3x2=6, then 6x3.14=18.84m
The answer is no, it couldn't be because the side lengths do not adhere to the triangle inequality theorem. which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side
3.5+8>13.5 Is not correct.
