Substation method x-2y=5 , 3x-5y=8

valina [46]

$x-2y=5 \\
3x-5y=8 \\ \\
\hbox{solve the first equation for x:} \\
x-2y=5 \ \ \ |+2y \\
x=2y+5 \\ \\
\hbox{substitute 2y+5 for x in the second equation:} \\
3(2y+5)-5y=8 \\
6y+15-5y=8 \\
y+15=8 \ \ \ |-15 \\
y=-7 \\ \\
x=2y+5=2 \times (-7)+5=-14+5=-9 \\ \\
\boxed{(x,y)=(-9,-7)}$

What are the real or imaginary solutions of the polynomial equation x*4-25=0

Paul [167]

Hello from MrBillDoesMath!

Answer:

Solutions: x = +\- 5i or x = +\- sqrt(5)

Discussion:

Factor x^4 - 25:

x^4 - 25 = (x^2+5) (x^2-5) => factor x^2 - 5

x^4 - 25 = (x^2+5)(x + sqrt(5)) (x - sqrt(5)) => factor x^2 + 5

x^4 = 25 = (x +5i)(x-5i) (x + sqrt(5)) (x - sqrt(5))

Hence the solutions are

x = +\- 5i and x = +\- sqrt(5)

Thank you,

MrB

Based on what you have learned about Malala’s viewpoints and setting, why is a blog a good way for Malala to speak up? Write two

NikAS [45]

Malala can express her opinion and share with others around the world. She can also be in control with her website/blog. I hope this helps! I think more info would’ve helped!
