Answer: 0.5
( f + g ) (x) = –2x + 6
( f – g ) (x) = 8x – 2
( f × g ) (x) = –15x2 + 2x + 8
g
f
)(x)=
4−5x
3x+2 f (2) = 2(2) = 4
g(2) = (2) + 4 = 6
h(2) = 5 – (2)3 = 5 – 8 = –3
Now I can evaluate the listed expressions:
(f + g)(2) = f (2) + g(2)
= 4 + 6 = 10
(h – g)(2) = h(2) – g(2)
= –3 – 6 = –9
(f × h)(2) = f (2) × h(2)
= (4)(–3)= –12
(h / g)(2) = h(2) ÷ g(2)
= –3 ÷ 6 = –0.5
Step-by-step explanation:
-8*21
= -168

Answer:
24
Step-by-step explanation:
To find f(#) or g(#), plug the number into each x of the equation.
f(x) = -x + 5
f(2) = -(2) + 5
Simplify the parentheses by multiplying.
f(2) = -2 + 5
Add.
f(2) = 3
g(x) = 3x + 2
g(2) = 3(2) + 2
Simplify the parentheses by multiplying.
g(2) = 6 + 2
Add.
g(2) = 8
Now they are asking you to multiply
f(2) • g(2)
3 • 8
= 24
Hope this helps!
Answer:
x=6
Step-by-step explanation:
this is a property
(8x-4)+(3x+17)=17x-23
11x+13=17x-23
23+13=6x
36=6x
x=6
