5r= T (total)
and r is of course movie posters.
3x + 2 > 5
3x > 3
x > 1
3x<= 9
x <= 3
there will be an open circle on 1 because it does not include 1 But a closed circle on 3.
1 < x <= 3
So it is D.
Answer:
Yes
Step-by-step explanation:
The intersection point of 10x+4y=18 and x+9y=19 is (1,2) on a graph.
Answer:
No
Step-by-step explanation:
Since an equilateral triangle has equal sides and angles, each angle measures 60°, which is acute. Therefore, an equilateral angle can never be obtuse-angled. A triangle cannot be right-angled and obtuse angled at the same time. Since a right-angled triangle has one right angle, the other two angles are acute.
