Answer:
(2,-4)
Step-by-step explanation:
-4+2=-2
10+-4=10-4=6
Answer:
There is one possible solution
Step-by-step explanation:
Here, we want to get the number of solutions
We can proceed to solve the equation
we have two y values so we can directly equate the x parts
-2x - 4 = 3x + 3
3x + 2x = -3-4
5x = -7
x = -7/5
To get y, we substitute
We can only get one value of y too
So we have a point (x,y) as the solution to the system of equations
The point-slope form:

m - slope
x₁, y₁ - the coordinates of a point
It passes through the points (1,-2) and (2,2).

Step-by-step explanation:
obtuse angle is an angle whose measure is more than 90 degree but less than 180 degree..
So,
170°
