If I remember correctly, the solutions are only on the solid line or in the shaded area? therefore Answers could be:
6.) (-3,0.5) (-4,0) (-2,0) (-2,-5) (-3,-5) (-4,-1) (-3,-1) (-2,-1)
7.) (-1,0) (-2,0) (-3,0) (0,-1) (-4,-1)
Answer:
92
Step-by-step explanation:
Given
2n + t² ← substitute n = - 4 and t = - 10 into the expression
= 2(- 4) + (- 10)² = - 8 + 100 = 92

David=x
Michelle=x-2
Karen=x-2+6=x+4
sum of ages=62
x+x-2+x+4=62
3x=60
x=20
age of Michelle=20-2=18
