Answer:
Step-by-step explanation:
It would be A, the first one.
Y = -4x + 7
This is the equation of the line. The slope is -4. The Y- intercept is 7
Suppose in 1992 Chris was x years old, his brother was then 2x years old.
6 years later in 1998, Chris is (x+6) years old, his brother is (2x+6),
(x+6)=(2/3)(2x+6)
x+6=(4/3)x+4
(4/3)x-x=6-4
(1/3)x=3
x=6
in 1992, Chris was 6, so in 2018 he will be 6+(2018-1992)=32 years old.
9.18-8%= 8.44 so I guess it’s $8.44? I’m sorry if it’s wrong
