5. -a-8a=-9; -9a=-9; a=1
6. -10x=10-20; -10x=-10; x=1
7. 24x+x=9+66; 25x=75; x=3
8. -9p-p=-10-30; -10x=-40; x=4
Step-by-step explanation:
Answer: y = 9
Step-by-step explanation:
Since two points are given , we will use the formula for finding the equation in two points form , which is
=
= 1
= -3
= -9
= -9
Substituting into the formula , we have
=
=
=
= 0
y + 9 = 0
y = 9
Answer: 3 lessons
Step-by-step explanation:
Matt starts swimming lessons on Day 5.
He then goes to swimming lessons every 10 days. The dates he went on lessons are therefore:
First lesson = Day 5
Second lesson = Day 5 + 10 days = Day 15
Third lesson = Day 15 + 10 days = Day 25
Fourth lesson = Day 25 + 10 days= Day 35
<em>He therefore only went for 3 lessons because the 4th lesson was after Day 30. </em>
