Let f(x)=-4x+7 and g(x)=10x-6. Find f(g(x))

1 answer:

4 0

$f(x) = -4x+7 \\ g(x) = 10x-6$

To find f(g(x)), insert the equation of g(x) into the x value for f(x)

$f(g(x)) = -4(10x-6)+7 \\ f(g(x)) = -40x + 24 +7 \\ f(g(x)) = -40x + 31$

27.) FEMALE LAWYERS There are 1,094,751 active lawyers living

SOVA2 [1]

Answer:

28.6%; 313,099

Step-by-step explanation:

Lawyers are either male or female, so if 71.4% are male, then 100% minus that are female.

100% - 71.4% = 28.6%

28.6% of 1,094,751 is:

0.286 × 1094751 = 313098.786

Rounded to the nearest whole number, there are 313,099 female lawyers.
