How do I work out the following simultaneous equations?x+3y=11 and 2x-y=11

Thank you, this is part of my half term homework and I really need to understand how to do this as soon as possible , thank you!

Answers

I'll show you two ways.

By substitution:

x+3y=11\n2x-y=1\n\nx=11-3y\n2x-y=1\n\n2(11-3y)-y=1\n22-6y-y=1\n-7y=-21\ny=3\n\nx=11-3\cdot3\nx=11-9\nx=2\n\n\boxed{(x,y)=\left(2,3\right)}

By elimination:

x+3y=11\n 2x-y=1|\cdot 3\n\nx+3y=11\n\underline{6x-3y=3}\n7x=14\nx=2\n\n 2+3y=11\n3y=9\n y=3\n\n\boxed{(x,y)=\left(2,3\right)}

What is the square root of 65

Answers

one way is factor
exg
if you wanted to find the square root of  36  you would factor
36=2 times 2 times 3 times 3
then group repeeting numbers then write only one of them
36=(2 times 2) times (3 times 3)
squareroot36=2 times 3=6

so factor 65
65=5 times 13
that doesn't help
next step
find squares close to that numbers
1^2=1
2^2=4
3^2=9
4^2=16
5^2=25
6^2=36
7^2=49
8^2=64
9^2=81

the answer is a little more than 8
the more exact one would be from a calculator (8.0622577482985)

A function f(x) is defined as f(x) = −8x^2. What is f(−3) ?F.−72
G. 72
H. 192
J.−576
K. 576

Answers

f(-3) = -8(-3)²
       = -8(9)
       = -72
Hence the answer is F
f(-3)=-8\cdot(-3)^2=-8\cdot9=-72
