Find an ordered pair that satisfies the function y=2x-12
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.
it be much appreciated if anyone could help out
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)

The side lengths of a triangle are 5,√3,√28. Is the triangle a right triangle? How would I solve this?
First to Answer:
The triangle would be a cute Scalene Triangle!
Here's all that you really can do with solving that
√28 =5.29150262213
√8 = 2.82842712475
Side a = 2.8
Side b = 5
Side c = 5.2
Angle ∠A = 31.788° = 31°47'18" = 0.55481 rad
Angle ∠B = 70.167° = 70°10'0" = 1.22464 rad
Angle ∠C = 78.045° = 78°2'42" = 1.36214 rad
Area = 6.84817
Perimeter p = 13
Semiperimeter s = 6.5
Height ha = 4.89155
Height hb = 2.73927
Height hc = 2.63391
Median ma = 4.9051
Median mb = 3.34515
Median mc = 3.10805

PLS HELP MEEE I NEED THE ANSWERS RN
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
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

Answer:
b=35
Step-by-step explanation:
Diagonals of a parallelogram always bisect each other, splitting it into two equal sections.
This means, b-8 is equal to 2b-43
b-8 = 2b-43
b+35=2b
b=35

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.
