–2x + 6. (f – g)(x) = f (x) – g(x). = [3x + 2] – [4 – 5x]. = 3x + 2 – 4 + 5x. = 3x + 5x + 2 – 4. = 8x – 2. (f × g)(x) = [f (x)][g(x)]. = (3x + 2)(4 – 5x). = 12x + 8 – 15x2 – 10x ... of the functions at x = 2 and then work from there. It's probably simpler in this case to evaluate first, so: f (2) = 2(2) = 4. g(2) = (2) + 4 = 6. h(2) = 5 – (2)3 = 5 – 8 = –3

Theo has $5 more than Denise and Denise has $11 more than Rudy. Together they have $45. How much money does Denise have?

Blizzard [7]

Let
x------> amount of money Theo has
y------> amount of money Denise has
z------> amount of money Rudy has

we know that
x+y+z=$45-----> equation 1
x=5+y-----> equation 2
y=11+z----> equation 3

substitute equation 2 in equation 1
[5+y]+y+z=45-------> 2y+z=40-----> equation 4

y=11+z----> equation 3
2y+z=40-----> equation 4

resolves the equations system
using a graph tool
see the attached figure

the solution is
y=17
z=6
x=5+y----> x=5+17----> x=22

the answer is
Denise has $17
