For (h+g)(x) you just add the two functions:
(h+g)(x) = 4x + 2x^2
For (h•g)(x) you multiply them:
(h•g)(x) = 4x • 2x^2 = 8x^3
For (h-g)(x) you subtract them:
(h-g)(x) = 4x - 2x^2
For (h-g)(-2) you sub -2 into the equation we just created:
(h-g)(-2) = 4(-2) - 2(-2)^2
(h-g)(-2) = -8 - 2(4)
(h-g)(-2) = -8 - 8
(h-g)(-2) = -16
The answer is x=7 and y=3
Answer:
y=x+100 for members and y=5x for visitors
Step-by-step explanation:
for the tables put 100 in 0 for the members and 0 for the visitors in 0 and follow the equation to fill the rest :)
The domain is all ur x values...the range is all ur y (or f(x) values
so ur domain is : { -6,-1,0,3}....1st answer choice
Answer:
x = 25
Step-by-step explanation:
Both angles are supplementary and will add up to 180°
5x - 5 + 2x + 10 = 180
collect like terms
5x + 2x +10 -5 = 180
7x + 5 = 180
7x = 180 - 5
7x = 175
x = 175/7
x=25
