Scale factor = 12 ÷ 6 = 2
61 ÷ 2 = 30.5 units
X=275+55= 330 biked
y=275-55= 220 bus
G(x) is the result of moving f(x) vertically up from -3 to 1
so k = 1 -(-3) = 4
The answer is I believe: 21
The numbers are irrational, so they can't be exactly written down
using only digits.
In exact form, they are
1 + √57
and
1 - √57 .
In rounded form, they are
8.54983
and
-6.54983 .
