Answer:
D. 24 Units
Step-by-step explanation:
tracing the points given we get a rectangle
the perimeter of a rectangle = 2a+2b
a=length
b= width
in this case a= 8
b= 4
the perimeter of a rectangle = (2*8)+(2*4)
the perimeter of a rectangle = 16+8
the perimeter of a rectangle = 24
Answer:
The lines are perpendicular
Step-by-step explanation:
we know that
If two lines are parallel, then their slopes are equal
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
we have
----> equation A
isolate the variable y
Divide by 7 both sides
The slope of the line A is 
----> equation B
isolate the variable y
Divide by 3 both sides
The slope of the line B is 
Compare the slope of both lines
so
----> the lines are not parallel
Find the product of the slopes
----> the lines are perpendicular
You would just break each one into 2 separate equations and solve for x/r. Then write the answer in between the two inequality signs- so the answers for 9 and 11 would look like this, just fill in the blanks with the answer you got: 3<span>≤____<5, 2>___>-2.
</span>
0<span>≤x-2<3
1</span><span>≤x-2 and x-2<3
</span><span>-1>2r-5>-9
-1>2r-5 and 2r-5>-9
this one just solve each one for z.
2z-1</span>≤5 or 3z-5>10
<span>z≤3 or x>5</span>
Answer: center (0,0), vertices (+/-5,0), foci (+/-4.6,0)
Step-by-step explanation:
