Let b be the initial amount of books. Steve sells half of his books, so the number of Steve's books become
Then, he buys 6 more, so the number increases by 6:
This number is now 14, so you have
Subtract 6 from both sides:
Multiply both sides by 2:
Answer:
Step-by-step explanation:
L'= 3, -3 M'= -3, -6 N'= -3, 3
Answer:
Step-by-step explanation:
height of triangle=√(11²-8.6²)=√(11+8.6)(11-8.6)=√(19.6×2.4)
=√(4×4.9×4×0.6)=4√(4.9×0.6)=4√2.94
area of triangle=1/2 bh=1/2×2×8.6×4√2.94
=34.4×√2.94
≈58.984
(2x - 5) (5x - 10)
Use FOIL
10x² - 20x - 25x + 50
10x² - 45x + 50
5( 2x² - 9x + 10)
2x -5
x -2
5(2x - 5)(x -2)
make each equal to 0
2x - 5 = 0
x - 2 = 0
2x - 5 = 0 x - 2 = 0
2x - 5 (+5) = 0 x - 2 (+2) = 0 (+2)
2x = 5 x = 2
x = 5/2
x = 5/2 , 2
hope this helps
Well, we see that it is a straight line
so the derivitive would be perpendicular
5/4 times what=-1
-4/5
the slope is -4/5
