4x=-3y+17 becomes 4x+3y=17
4x+3y=17
3x-4y=-6
alrighty
elimination
muliply first equation by 4 and 2nd by 3 and add them
16x+12y=68
9x-12y=-18
add them
25x+0y=50
25x=50
idivide both sides by 25
x=2
sub back
3x-4y=-6
3(2)-4y=-6
6-4y=-6
-4y=-12
y=3
(x,y)
(2,3)
Divide 28.26 by 3.14
The answer is 9

Answer:
I got "D'E' will be parallel
Step-by-step explanation:
The distributive property is...
a(b + c) = ab + ac
or
a(b - c) = ab - ac
So...
root6 (root30 - 2)
= root6 x root30 - root6 x 2
= root180 - 2root6
= 6root5 - 2root6
6root5 means 6 x root5
2root6 means 2 x root6
