Answer:
A. 693
Step-by-step explanation:
The question is asking you to input 7 into both functions and then multiply them together.
First insert 7 into f(x) = 7 + 2x, 7 times 2 is 14, plus 7 = 21
do the same with g(x) = 5x - 2, 5 times 7 is 35, minus 2 = 33
fg(7) is saying to multiply fg together as a variable next to another variable does. leaving the answer as 693.
G(x)= -3x+4
substitute x with -2
g(-2)= -3(-2)+4= 6+4=10
substitute x with 4
g(4)= -3·4+4= -12+4= -8
so g( -2)=10 and g(4) = -8
The value of g(-2) is larger than the value of g(4)
The square root of 361=19
Answer:
20%
Step-by-step explanation:
12/15 = .8
subtract from 1
gives you .2
convert to a percentage
.2 = 20%
