-5x(x+3)-7(x-3)/x^2-9= -5x^2-15x-7x+21/x^2-9= -5x^2-22x+21/x62-9
(4,3)(2,2)
slope = (2 - 3) / (2 - 4) = -1/-2 = 1/2
y = mx + b
slope(m) = 1/2
use either of ur sets of points...(4,3)...x = 4 and y = 3
now we sub and find b, the y int
3 = 1/2(4) + b
3 = 2 + b
3 - 2 = b
1 = b
so ur equation is : y = 1/2x + 1 <==
9.4061,
9.07,
9.007,
9.4
Because ones are equal for all numbers, we are going to begin to compare from the second digits (tenths).
Greater :
9.4061 and 9.4.
Greatest is this group is 9.4061, then will go 9.4.
Smaller :
9.07 and 9.007
Greatest in this group is 9.07, and then will go 9.007.
So, from greatest to smallest : 9.4061 , 9.4 , 9.07 , 9.007.
From least to greatest :
9.007, 9.07, 9.4, 9.4061.
Answer:
$11.20 per hat.
and $5.60 per bag
Keisha has $13.20 left over
Step-by-step explanation:
First, I multiplied .70 by 16 and got 11.20 per hat
Then, I multiplied .35 by 16 and got 5.60 per bag
Lastly, I added 11.20 to 5.60 and got 16.80, and subtracted 16.80 from 30 and got 13.20.....
