Mathematics

Answer:

dependent

Step-by-step explanation:

y=2x-8 and 2x-y=8

First equation is already solve for y

LEts solve the second equation for y

2x-y=8

Subtract 2x on both sides

-y=-2x+8

Divide the whole equation by -1

y=2x-8

After solving for y, both equation are same

When both the system of equation are same then  it has infinite solutions.

They are said to be dependent.

Note that 2x-y=8 can be solved for y:  y=2x-8.  This is identical to the first equation.  The graph of one is exactly the same as the graph of the other.  Thus, the two equations are dependent.

Can someone please explain how to get this answer? Recursive formula help!<br>t(1)=3 (in picture)
kipiarov [429]
T(1) = 3, t(n) = -2t(n-1) + 1
So t(2) = -2(t(1)) + 1 = -2(3) + 1 = -5
t(3) = -2(t(2)) +1 = -2(-5) +1 = 11
t(4) = -2(t(3)) +1 = -2(11) +1 = -21
t(5) = -2(t(4)) +1 = -2(-21) +1 = 43

Solve for x. Show the equation you used and your work.
IgorC [24]
Here, You need to apply "Proportionality Theorem"
According to this theorem, the ratio of components of a leg would be equal to the ratio of corresponding components of another leg.

In mathematical form, 
TV/VS = TW/WU

Substitute their values, 
14/6 = 21/(x+4)
14(x+4) = 21*6
14x+56 = 126
14x = 126-56
x = 70/14
x = 5

In short, Your Answer would be 5

Hope this helps!
