The least amount she must save is $190
work: 475-285 =190
Answer: -0.7
Step-by-step explanation:
Answer:
d. f opens upward with a y-intercept at (0, 2); h opens downward with a y-intercept at (0, -2)
G of f means plug f(x) into g(x)
but we want at x=2
we can solve to ways
1) find g(2)=7x-4
= 10
f(10)= 10 / (x-1)
answer is 10/ 9
method 2 is
(f(g)x)= 10/ ((7x-4)-1)
=10/(7x-5)
now x=2
=10/(7(2)-5)
=10/9
same answer, hope this helps
