Answer:
If simplifying, then
x^3 -13x^2 -x -49
Step-by-step explanation:
To do this, I would start off with the left side (use PEMDAS)
Use FOIL (First, Outside, Inside, Last)
x^3 + -9x^2 + 6x + -54 - (4x^2 + 7x - 5)
Bring negatives inside parenthesis
x^3 -9x^2 +6x -54 -4x^2 -7x +5
Combine like-terms
x^3 -13x^2 -x -49
(x^2 +6)(x-9)-(4x^2 +7x-5)
x^2 + 6 * x - 9 - 4x^2 - 7x + 5
x^2 + 6x - 9 - 4x^2 - 7x + 5
(x^2 - 4x^2) +(6x - 7x)+(-9 + 5)
(-3x^2)+(-x)+(-4)
=-3x^2 -x - 4

Marcus reads in a magazine article that 62% of teenagers prefer Batman over Iron Man. He decides to test this so he takes a simple random sample of 50 people at Wal-Mart on a Sunday afternoon. What is the probability that he finds exactly 40 Batman fans? Round to the nearest thousandth.
Answers
Answer:
The probability is 0.003
Step-by-step explanation:
If 62% prefers Batman, the percentage that prefers Iron man will be (100-62)% = 38%
So the probability of finding a teenager that likes batman will be 62/100 = 0.62
The probability of finding a teenager that prefers iron man will be 38/100 = 0.38
Now, we want to find the probability that out of 50 people at Walmart on a Sunday, exactly 40 prefers Batman
We can use the Bernoulli approximation of the binomial theorem ;
let probability of liking Batman be q and that of iron man be q
Thus the approximation will be;
P(X = 40) = 50 C 40 (0.62)^40 (0.38)^10
= 0.003200147531
To the nearest thousandth, this is 0.003

Answers
Answer:
1) 5 & 9
5=Corresponding Angle
9=Alternate Exterior Angle
2) 7 & 8
We know 4 is supplementary to 8. Since that is true, 7 & 8 are also.
8=Corresponing angle to 4
7=Verticle angle to 8
3) We know 1 and 3 equal 180
x-20+x+40=180
2x+20=180
2x=180-20
2x=160
x=80
<2=X+20
=80+20
=100
Angle 2 is the same as angles 5 and 6 added together.
We know angle 5 is the same as angle 1 (corresponding angles).
<1=X-20
=80-20
=60
Now that we know <2=100 and <5=60, we can figure out <6
100-60=40
<6=40°

suppose you are buying two kinds of chips for a party. Each bag of potato chips cost $2.50 and each bag of corn chips cost $2.90. You must have at least 100 bags of chips for the party and the total cost of the chips can be no more than $350
Part A:Write a system of two inequalities that describe the situation
Part B: Write one possible solution to the problem in sentence form
Answers
Answer:
At least means ≥
No more than means ≤
Let x = number of bags of potato chips
Let y = the number of bags of corn chips
x+y≥100
2.50x+2.90y≤$350
Let's try x=80 and y=20 (We know that is equals 100 so it will work for the first equation
2.50(80)+2.90(20) = 258 which is ≤$350
Buy 80 bags of potato chips and 20 bags of corn chips is one possibility.

Tavon has a gist card for $145 that losses $3.50 for each 30-day period is not used. He has another gift card for $125 that losses $3 for each 30-day period it is not used. A. Write and solve an equation for the number of 30-day periods until the value of the gift cards will be equal. B. What will the value of each card be when they have equal value?
Answers
Step-by-step explanation:
A. For Tavon's gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=145-3.5x------1
for Tavon's second gift card the equation is
let y be the total amount
let x be the number of 30 day period
y=125-3x-------------2
B. equating 1 and 2 we have
145-3.5x=125-3x
solve for x we have
145-125=-3x+3.5x
20=0.5x
divide both sides by x we have
x=20/0.5
x= 40
put x=40 in
y=145-3.5*40------1
y=145-140
y=$5
put x=40 in
y=125-3*40------1
y=125-120
y=$5
