So you use x = 2.
x-2 = 0
x+7=9
so (0,9) (x,y)
Answer:
Either one: the two line have a point in common, or infinite: they are the same line.
The actual speed of the plane with the wind:
v² = ( 150 + 50 · cos 45°)² + ( 50 · sin 45°)²
v² = ( 150 + 35.355 )² + 35.355²
v² = 34,356.467 + 1,249.976
v = √35,606.452
v = 188.7 mph
Answer:
A number line with an open circle on −2, a closed circle on 5, and shading in between
Step-by-step explanation:
solve it you get x>-2
and 3x <=15
x<=5
so its close on 5 and open on -2
