Answer:
180-84-60= 36 degrees
Step-by-step explanation:
a triangle is composed of 3 angles up to 180 degrees 180-84 is 96 96-60 is 36.
If we substitute z = 2 - x - y in the last 2 equations it simplifies to 2 equations in x and y:=
x^2 + y^2 + xy - 2x - 2y = 5 and
-x^2 - y^2 - xy + 2x + 2y = -5
if we add these we get 0 = 0 so there are infinite solutions
First you need to find the slope.
You do this by adding x to both sides to get 3y=x-12
Then, you divide by three on both sides to get y=1/3x -4
to find the new y intercept you insert the point and the slope in the equation
2=1/3(18)+b
You multiply 1/3 and 18 to get 2=6+b
Finally you subtract 6 on both sides to get -4=b.
This means that the equation of the line is the same as the given line
Answer:
1/9
Step-by-step explanation:
- Plug 9 and 81 in:
- 9/81 = 1/9
