F * g means exactly that.
Which is that you should multiply the definitions of the functions.
(x+7)(1/x-13) = x/x-13 + 7/x-13 = x+7/x-13
x+7/x-13
The domain of this function, is x<13 and x>13.
But not 13. Because 13-13 = 0
And it is not legal to divide a number by 0.
Hence, f*g(13) is not defined.
Answer:
x=50
Step-by-step explanation:
d=rt
9.50mi/hr(.50 for half hour) *1.75(.75 because 3/4 equals that) =distance
=16.625
=16.63
how does that sound?
1) answer is 8 because 8 + 7 = 15
2) answer is 8 because 8 + 18 = 26
3) answer is 25 because 25 - 6 = 19
4) answer is -1 because -1 - 3 = -4
Y- y1 = m (x-x1)
y+1 = 4(x+3)
y+1=4x+12
y=4x+11
