Pythagoras says
a squared = b squared + c squared so
xsquared= 21 squared +17 squared
x squared = 441 + 34
x squared = 475
x = squared root of 475
x= 21.79mi

Answer:
Step-by-step explanation:
Multiplying x+6y=-3 with 2 so its equal to first eqn,
Eliminating,
2x + 3y = 3 (1)
2x +12y = -6 (2) (because subtracting)
------------------
-9y =9
∴y=-1
eq. y in 1
2x -3=3
2x=3+3
x=6/2
=3

Answer: The correct option is option 6, (-4,-11).
Step-by-step explanation: You subsitute 2x-3 for y.
2x-3=3x+1
-x=4
x=-4
Plug in -4 for x in an equation.
y = -8 - 3
y = -11
(-4,-11)
