For all values of x, f(x) = x^2 + 1 and g(x) = x-5
(a) Show that fg(x) = x^2 - 10x + 26
(b) Solve fg(x) = gf(x)
Answer:
a) f g(x) = x³ - 5 x² + x -5
b) g(f(x) = x³ - 5 x² + x -5
Step-by-step explanation:
Step(i):-
Given that f(x) = x² + 1 and g(x) = x-5
a)
f(g(x)) = f(x-5) = (x-5)²+1 = x² - 10x +25 +1 = x² - 10 x +26
Step(ii):-
a) f g(x) = f(x) g(x) = (x² + 1 )(x-5) = x³ - 5 x² + x -5
b) g(f(x) = g(x) f(x) = (x-5) (x²+1) = x³ - 5 x² + x -5

What is the best prediction of the amount of money earned when the lemonade stand has been open for 9 hours
Answer: $50
Step-by-step explanation: Draw a line through the apparent center of the scattered dots. See where that line intersects 9 in the time scale (x-axis numbers) and the dollars earned scale (y-axis numbers)
It could be 50 or 55, but since there are a few more dots below the apparent midline, it may be best to use the lower estimate.

Over what interval is f(x) negative? Justify your answer.
Answer in interval notation is (-3, 1)
This is the same as saying -3 < x < 1
=====================================================
Explanation:
Since y = f(x), this means we're looking for points on the red curve such that they have a negative y coordinate. Visually, we're looking for points that are below the horizontal x axis.
These points are shown in the diagram below. I've marked the section we're after in blue. This blue section spans from x = -3 to x = 1. We exclude both endpoints because each x value leads to f(x) = 0, but we want f(x) values smaller than zero.
Of the 300 television sets sold at an electronics store last month, 90 were flat screen TV's. What is the ratio of flat-screen TV's to other TV's sold last month?
I don't know how to do this. I would appreciate some help. thanks!!
Answer:
300 television sets total
300 - 90 flat screens = 210
flat screens 90:210 other TVs
now divide each side of the ratio by a common factor to simplify. I'm going to use 30
flat screens 3:7 other TVs
this cannot be simplified any further so the ratio is
flat screens 3:7 other tvs

Answers:
x= -10 and y= 16
3y = -6x - 12
3y = -6(-2y+22) -12
3y = 12y - 144
3y + -12y = 12y -144 + -12y
-9y = -144
divide -9 on both sides
y= 16
x= -2y+22
x= -2y+22
x= (-2)(16)+22
x= -10

Factor: 16w3 – u4w3
Answer:
w^3(4 + u^2)(2 + u)(2 - u)
Step-by-step explanation:
6w^3 – u^4w^3
w^3(16 – u^4)
w^3(42 - ((u^2)^2)
w^3(4 + u^2)(4 - u^2)
w^3(4 + u^2)(22 - u^2)
w^3(4 + u^2)(2 + u)(2 - u)
