<span> x</span>² <span>- 4x - 5 = </span>(x + 1)(x - 5)
Answer:
T.
Step-by-step explanation:
The ordered pair (-2,-1) can also be represented by (x,y). To check the inequality we can substitute the values into the given inequality.
![y>-\sqrt{x+11+1}](https://tex.z-dn.net/?f=y%3E-%5Csqrt%7Bx%2B11%2B1%7D)
![-1>-\sqrt{-2+11+1}](https://tex.z-dn.net/?f=-1%3E-%5Csqrt%7B-2%2B11%2B1%7D)
![-1>-\sqrt{10}](https://tex.z-dn.net/?f=-1%3E-%5Csqrt%7B10%7D)
![-1>-3.1622](https://tex.z-dn.net/?f=-1%3E-3.1622)
After substituting the values, we then have a clear view that -1 is Greater than -3.1622.
Answer:
x = 3y + 1
Step-by-step explanation:
0-(-1) = 1
1-0 = 1
2-1 = 1
1-(-2) = 3
4-1 = 3
7-4 = 3
As x increases by 1, y increases by 3. At x = 0, y is already 1. Thus:
x = 3y + 1
3 rolls of steamer + 2 packages of balloons = $10 -------------- (1)
2 rolls of steamer + 1 package of balloons = $6.25 --------- (2)
(2) x 2:
4 rolls of steamer + 2 package of balloons = $12.50 --------- (2a)
(2a) - (1):
1 roll of steamer = $2.50 ----------- Sub into (1)
3 ($2.50) + 2 packages of balloons = $10
$7.50 + 2 packages of balloons = $10
2 packages of balloons = $10 - $7.50
2 packages of balloons = $2.50
1 packages of balloons = $1.25
1 packages of balloons = $1.25
1 roll of steamer = $2.50
1 packages of balloons + 1 roll of steamer = $1.25 + $2.50 = $3.75
