9514 1404 393
Answer:
- The graph has an open circle at 7.
- The arrow points left.
Step-by-step explanation:
Adding 10 and dividing by 4, we have ...
4x < 28
x < 7
The comparison does not include the "equal to" case, so the circle at x=7 is open. Values of x less than 7 are in the solution set. Those values are found to the left of 7 on the number line.
- The graph has an open circle at 7.
- The arrow points left.
I'm not to clear on what this triangle is trying to say but if 18 is a side and 12 is a side let's use the Pythagorean theorem to solve for the other side
18²=a²+12²
324=a²+144
180=a²
√180 = a
13.41 =a
since x look about twice a
x=2*13.41
x=26.8
805 divided by 5 equals 161
- 5 + 10 = 5 ( False )
- 5 - 10 = - 15 ( True )
-5 + ( - 10 ) = - 15 ( True )
-5 - ( - 10 ) = - 5 + 10 = 5 ( False ) ;
The correct answers are b) and c).
