So you need help with creating the table ?
Exact Form: 
Mixed Number: 
Decimal Form: 1.6(this is a repeating decimal)
The answer is A. 1 2/3
v varies directly with height means
v/h=k were k is a constant
or also h/v=k where k is a constant (this is a different k than previous)
so if h=12 and v=300 then
h/v=12/300=1/25=k
so the relationhip could be h/v=1/25
if you di v/h, then
v/h=300/12=25/1=25=k
so the relationship could be v/h=25
2x + 2y + 7z = 9.....multiply by -1
2x + 6y + 5z = 7
--------------------
-2x - 2y - 7z = -9 (result of multiplying by -1)
2x + 6y + 5z = 7
-------------------add
4y - 2z = -2
2x + 6y + 5z = 7....multiply by -1
2x + 5y + 4z = 9
-------------------
-2x - 6y - 5z = -7 (result of multiplying by -1)
2x + 5y + 4z = 9
-------------------add
-y - z = 2
4y - 2z = -2
-y - z = 2 ......multiply by -2
-----------------
4y - 2z = -2
2y + 2z = -4 (result of multiplying by -2)
----------------add
6y = -6
y = -6/6
y = -1
4y - 2z = -2
4(-1) - 2z = -2
-4 - 2z = -2
-2z = -2 + 4
-2z = 2
z = -2/2
z = -1
2x + 2y + 7z = 9
2x + 2(-1) + 7(-1) = 9
2x - 2 - 7 = 9
2x - 9 = 9
2x = 9 + 9
2x = 18
x = 18/2
x = 9
solution is : x = 9, y = -1, and z = -1
I am not getting any of ur answer choices....but when I sub my answer choices back into all 3 of the original equations, they come out true
Answer:
The point of intersection is (-1,-3)
Step-by-step explanation:
Line A has a slope of 3/2 and passes through the point (3,3)
It is equation is:
Line B has a slope of -1/3 and passes through the point (-4,-2).
It's equation is
To find their point of intersection, we solve the two equations simultaneously.
Let's equate the right hand sides:
Expand:
Put x=-1 in the first equation:
The point of intersection is (-1,-3)
