Solve for e. T=e29 e=±3T√T e=±3T e=±3T√ e=±9T√

Anon25 [30]

Answer:

option (3) is correct.

$e= \pm 3\sqrt{T}$

Step-by-step explanation:

Given $T=\frac{e^2}{9}$

We have to solve for e.

Consider the given statement,

$T=\frac{e^2}{9}$

Cross multiply, we get,

$\Rightarrow 9T={e^2}$

Taking square root both sides , we get,

$\Rightarrow \sqrt{9T}=e$

We know square root of 9 is 3.

$\Rightarrow \pm 3\sqrt{T}=e$

Thus, option (3) is correct.

$e= \pm 3\sqrt{T}$

Solve the system using combination method to get a solution (x,y) 4x+7y=10 -4x-6y=28

PIT_PIT [208]

$\left \{ {{4x+7y=10} \atop {-4x-6y=28}} \right. \\\\add\ those\ two\ equations\\\\
y=38\\\\
4x+7y=10\ \ \ | subtract\ 7y\\\\
4x=10-7x\ \ \ \ | divide\ by\ 4\\\\
x=\frac{10-7x}{4}=\frac{10-7*38}{4}=\frac{10-266}{4}=\frac{-256}{4}=-64\\\\
solution:\\ \left \{ {{y=38} \atop {x=-64}} \right.$
