Answer:
(f+g)(x) = 5x + 3
Step-by-step explanation:
f(x) = 2x - 6 and g(x) = 3x + 9, find (f+g)(x)
(f+g)(x) = f + g = (2x - 6) + (3x + 9) = 5x + 3
(f+g)(x) = f + g = 5x + 3
Answer:
-17
Step-by-step explanation:
f(-5)= 3*(-5)-2
= -15-2

Answer:
$62.80
Step-by-step explanation:
$500 x 4% = $20
$350 x 4% = $14
$720 x 4% = $28.80
$20 + $ 14 + $28.80 = $ 62.80 commission
Answer:
6g7
Step-by-step explanation:
Cause it has a slope of -3/2, we could call its equation: y= -3/2x+b
and we have to find out b
In addition, it has a y-intercept of -1, that means this line goes through the point A(0;-1). So we could replace x=0 and y= -1: -1 = -3/2x0+b and we have b= -1
We obtain the equation: y= -3/2x-1
