Answer:
Step-by-step explanation:
Since lines 1 and 2 are parallel, <2=<6 because corresponding angles of parallel lines are congruent. <8 is the vertical angle of <6 meaning it's equal to <6. <8=115 degrees. <7 is the supplement of <6 and therefore 180-<6=<7. 180-115=65.
Answer:
1. x >/= -1
2. x < 4
3. x </= -1
4. x >/= -2
5. x < -3
6. x </= 7
Step-by-step explanation:
This function is consist of two subfunction with different domains.
f(-1) means x= -1 ≤ 1 and we will use subfunction -x+2 => f(-1)=-(-1)+2= 1=2=3
f(3) means x=3 > 1 and we will use subfunction x∧2-4x+6 =>
f(3)= 3∧2-4*3+6= 9-12+6=3
Good luck!!!
