or
5+3/112
Answer:√(6/5) and √(9/7) and √(7/5)
Step-by-step explanation:
1/4 = 0.25
5/4 = 1.25
√(6/5)=1.095445...
√(9/7)=1.1338934...
√(7/5)=1.1832159...
Thus, any non-perfect square radicals will be irrational numbers.
Hope this helps!! :)

Solution:
1) Solve for x in 3x+7y=-1
x=\frac{-1-7y}{3}
2) Substitute x=\frac{-1-7y}{3} into 4x-3y=11
\frac{4(-1-7y)}{3}-3y=11
3) Solve for y in \frac{4(-1-7y)}{3}-3y=11
y=-1
4) Substitute y=-1 into x=\frac{-1-7y}{3}
x=2
5) Therefore,
x=2
y=-1
Done!
Answer:
B'(- 2, 2 )
Step-by-step explanation:
Assuming the dilatation is centred at the origin, then multiply the coordinates of B by the scale factor 2, that is
B(- 1, 1 ) → B'(2(- 1), 2(1) ) → B'(- 2, 2 )
