The solution of two equations/lines is their intersect point.
Therefore, there can only be one intersection point/solution, because these lines are neither parallel or identical.
In the graph you can see that they intersect at (x,y)=(2,3) which is your solution and option b or d as one of them seems to be mistyped :)
@question2
y=kx+b
both your equations share the same k=-2:
y=-2x+3
y=-2x-1
therefore these lines are parallel and don't have any intersection as they are always at different y values (the b)
Answer:
33°
Step-by-step explanation:
Complementary angles add up to 90°
If we set the other angle as ∠K,
m∠M + m∠K = 90°
57° + m∠K = 90°
m∠K = 33°
Thus, the other angle would be 33°
Answer:
36
Step-by-step explanation:
Using the angle addition postulate
angle 1+angle 2+angle 3=180
Angle 2 is 90 degrees,
Angle 1 is 2x degrees
Angle 3 is 3x degrees
Plug this into equation
Plug 18 into 2x
