Answer:
(8y+8)²+(4x²+16)=0
Step-by-step explanation:
Given:
(64y²)+(4x²)+128y+16x+64=0
Find:
Equation into the appropriate form
Computation:
(64y²)+(4x²)+128y+16x+64=0
(8y)²+(2x)²+128y+16x+64=0
(8y)²+(2x)²+2(8y)(8)+2(2x)(4) + 8²=0
(8y+8)²+(4x²+16)=0
With $17.50 she can get 11 2/3 gallons. 11 (she just got) + 8 (that she had) = 19 gallons. 19 x 27 MPG = 513 Miles.
27 divided by 3 = 9 (9 is a third of the MPG) 9 x 2 (since it was 2 thirds that were left) = 18
In total she can drive 531 miles.
Answer:
m=-3/5
Step-by-step explanation:
(x+2)(x+1) = x^2 + x + 2x + 2
simplify it
x^2 + 3x + 2

Step-by-step explanation:
To reflect a shape about the 
-axis, simply reflect each of its vertex across the -axis.
The 
-coordinate of a point gives the vertical position of the point. On the other hand, the -axis is horizontal. Reflecting the point would invert the -coordinate of that point.
For example, reflecting 
about the -axis would give 
.
Similarly, to move the polygon up by 
units, simply move every one of its vertex up by units. Keep in mind that the order of the translation does matter. In this question, reflect each point before moving them upward.
To move a point up by units, simply to its -coordinate. Aftering moving , the reflection of 
, up by two units, the new point would have coordinates .
