Answer:
Step-by-step explanation:
This is the curve of with some transformations applied.
The curve appears to be moved left 3 units and down 1 unit.
The pictured curve is that of or after simplifying .
Check it!
Plug in some points on the given curve into the equation we said that fits it.
Here are some points I see on the curve:
(-3,-1)
(-2,0)
(1,1)
Let's see if those points satisfy our equation.
with :
is true so (-3,-1) does satisfy .
with :
is true so (-2,0) does satisfy .
with :
is true so (1,1) does satisfy .
All three points that crossed nicely fit the equation we described.

Answer: 153.94cm
Step-by-step explanation:
Consider the ordering
... -2 < -1
Now consider the ordering of their absolute values:
... 1 < 2
_____
Hopefully, you see that changing the sign reflects the sequence across the origin, so that the ordering is reversed when the signs are changed.
Answer:
The Cost of yellow shirts is $15 and the cost of purple shirt is $ 60
Step-by-step explanation:
Let cost of one yellow shirt be x
and the cost of one purple shirt be y
On Monday
5x + 7y = 165--------------------(1)
On Tuesday
4x + 11y = 213----------------------(2)
To solve (1) and (2)
multiplying eq(1) with 4
20x + 28y = 660--------------------(3)
multiplying eq(2) with 5
20x + 55y = 1056-------------------(4)
Subtracting (3) from (4)
20x + 55y = 1056
20x + 28y = 660
(-)
-----------------------------------
0x +27y = 405
-----------------------------------
y = 15
Substituting y value in eq(1)
5x + 7(15) = 165
5x + 105 =405
5x =405 -105
5x =300
x = \frac{300}{5}
x =60
