Answer:
No and Yes.
Step-by-step explanation:
The inequation is y ≥-x+7 and the pair is (x,y)=(-1,-1). Then:
-1≥ -(-1)+7
-1 ≥ 1+7
-1 ≥ 8, but this is not true, so (-1,-1) is not a solution of y ≥-x+7.
On the other hand, the inequation is y>(3/4)x-5 and the pair is (5,3). Then:
3>(3/4)(5)-5
3>(15/4)-5
3> -5/4 and this is true, so (5,3) is a solution of y>(3/4)x-5.
4x-y=8
-4x (subtract -4x from both sides)
-Y=-4x+8
/-y (divide -1y from both sides)
Y=4x-8
answer is: y=4x-8
(4,1)
(13/59)(c/58)=117/1711
13c/3422=117/1711
13c=234
c=18
So there are 18 clubs instead of 13 meaning that there is an extra 5 clubs in the deck.
Since there were 59 cards, there was 7 extra cards in all. The 7 extra minus the 5 extra clubs leaves 2 extra spaces.
So there were two extra spades in the deck.
Then the surveyor should ask how many people do they read books very simple
