Help me please with this math. find x and y​
erastova [34]

Answer:X= 1.84. Y= 3.08

Step-by-step explanation:

-9x+8y =8 ............i

-8x+10y= -16........ii

Multiply equation I by 8

Multiply equation ii by 9

-72x+64y = 64 ..... iii

-72x+90y = 144 ..... iv

Subtract iv from iii

-26y = -80

y= 80/26

y= 3.08

Put the value of y in equation i

-9x+8y =8

-9x+8(3.08) = 8

-9x+24.64 = 8

-9x = 8-24.64

-9x=-16.64

Divide both side by 9

-9x/-9 = -16.64/-9

X= 1.84

Solve for e. T=e29<br><br><br> ​​ e=±3T√T<br><br> e=±3T<br><br> e=±3T√<br><br> ​ 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}

PLEASE ANSWER ASAP!!!!! DONT NEED much explanation How many solutions does this system have? (photo below)
Tema [17]

Answer:

infinite solutions

Step-by-step explanation:

Multiply the first equation by 2

2(3x-5y) = 2*15

6x - 10y = 30

This is the same as the second equation

They are the same line

This means there are infinite solutions
