Answer:
10, 12 and 14Step-by-step explanation:
x - an integer
2x - an even integer (the first and the smaller of the three)
Consecutive integers increase always by 2
2x+2 - next even integer consecutive to 2x (the middle one)
2x+2+2=2x+4 - the last consecutive even integer (the largest)
2•(2x+2) - twice the middle number
2x+2•(2x+2) - the sum of the smallest number and twice the middle one
2x+4+20 - 20 more than the largest number
2x+2•(2x+2) = 2x+4+20
2x + 4x + 4 = 2x + 24
-2x -2x
4x + 4 = 24
÷2 ÷2
2x + 2 = 12 ← the middle number
-2 -2
2x = 10 ← the smallest number
2x+4 = 10 + 4 = 14
Check: 10+2•12=34; 14+20=34

Why is 3^-2 not a negative number?
The rule you use is x^(-k) = 1/(x^k)
In this case x = 3 and k = 2, so,
3^(-2) = 1/(3^2) = 1/9
--------------------------------------------
One way to think of it, is to consider the equation below
3^2*3^x = 1
We can solve for x like this
3^2*3^x = 1
3^(2+x) = 1
3^(2+x) = 3^0
2+x = 0 .... the bases are equal, so the exponents must be equal
x = -2
meaning that
3^2*3^x = 1
updates to
3^2*3^(-2) = 1
Now isolate the 3^(-2)
3^2*3^(-2) = 1
3^(-2) = 1/(3^2)
3^(-2) = 1/9

Zoe needs to rent a car. Kara's Kar Kompany charges $22 per day and a $100 cleaning fee. Callie's Car Company charges $26 per day and has a $40 cleaning fee. After how many days would the rental cost be the same for both car rental companies?
A) 18 Days
B) 13 Days
C) 15 Days
D) 8 Days
Answer:
C) Fifteen days
Answer:
C) 15 days
Step-by-step explanation:
To answer this question, we must make an equation, so lets use the variable 'd' equal the number of days a car is being used for:
22d + 100 = 26d + 40
Now, we combine like terms:
22d + 100 = 26d + 40
-22d -22d
100 = 4d + 40
-40 -40
60 = 4d
/4 /4
d = 15
So, the rental cost will be the same for both car companies after 15 days

You are buying cupcakes for a school party. They are in a package of 6 for $8.50. You have budgeted no more than $40 to spend. If cost of the cupcakes is a function of the number of packages purchased, what is the largest element of the domain in this situation?
Answer: Largest element in the domain is 4
The largest number of packages you can buy is 4
======================================================
Explanation:
1 package costs 8.50*1 = 8.50 dollars
2 packages cost 8.50*2 = 17 dollars
3 packages cost 8.50*3 = 25.50 dollars
and so on. In general
x packages cost 8.50*x = 8.50x dollars
where x is a place holder for a positive whole number (1,2,3,...)
The total amount spent is 8.50x and the budget is $40
This means,
[tex]8.50x \le 40\\\\x \le \frac{40}{8.50}\\\\x \le 4.70588\\\\x \le 4\\\\[/tex]
We round down regardless of how close we are to 5.
If x = 4, then 8.50*x = 8.50*4 = 34
While if x = 5, then 8.50*x = 8.50*5 = 42.5
So we see we go over budget if we buy x = 5 packages.
This makes x = 4 the largest in the domain.
Recall the domain is the set of allowed x inputs. In this case, x is a positive whole number (since we can't buy half a package for instance).
Which of the following equations produces a linear function?
A y=x?
B = 2x + 3
C y = |x|
D y=2x2 + 3x - 2
Answer:
a, b, and c
Step-by-step explanation:
all of them are in the form y=mx+b except for c, which does not have a constant slope throughout the entire line, it will be decreasing or negative until 0, and then increasing or positive after 0, so the slopes would not be the same.

Victoria filled up her car with gas before embarking on a road trip across the country. The car uses 1.75 gallons of gas for every hour driven, and after driving for 4 hours, there were 7 gallons of gas left in the tank. Write an equation for G,G, in terms of t,t, representing the number of gallons of gas remaining in Victoria's gas tank after tt hours of driving.
Answer:
G = 14 - 1.75(t)
Where G is the number of gallons of gas remaining;
14 represents the amount of gas in gallons in the full gas tank of the vehicle
t is the number of hours
Step-by-step explanation:
Here, we want to write an equation.
We are told that the car uses 1.75 gallons of gas every hour and after 4 hours 7 gallons were left
In the 4 hours, the amount of fuel used will be 1.75 * 4 = 7 gallons
So therefore since we have 7 gallons left, the amount of gallons in the full tank of the vehicle will be 7 + 7 = 14 gallons
Hence, the equation we want to write will be;
G = 14 - 1.75(t)
Let cos(2x) - cos(x) = 0 where 0° < x <180° what are the possible values of x
Answer:
x= 120°
Step-by-step explanation:
cos(2x)-cos(x)=0
[tex]\Rightarrow 2\cos^2x-\cosx-1=[/tex]0 [as [tex]\cos(2x)=2\cos^2x-1[/tex]]
[tex]\Rightarrow 2\cos^2x-2\cosx +\cosx-1=0[/tex]
[tex]\Rightarrow 2\cos x(\cos x-1) +(\cos x-1)=0[/tex]
[tex]\Rightarrow (\cos x-1)(2\cos x +1)=0[/tex]
[tex]\Rightarrow \cos x-1=0 \;or\; 2\cos x +1=0[/tex]
[tex]\Rightarrow \cos x=1 \;or\; \cos x =-1/2[/tex]
[tex]\Rightarrow x=\cos^{-1}1 \;or\; x =\cos(-1/2)[/tex]
For [tex]x=\cos^{-1}1[/tex] and 0° < x <180°
There is no possible value of x.
For [tex]x =\cos(-1/2)[/tex] and 0° < x <180°
The possible value of x is
x= 120°

The members of a small town's local arts council are selling raffle tickets. The art council decides that the top three raffle ticket sellers will share a portion of the profits. The second-place seller will receive twice as much as the third-place seller. The first-place seller will receive $20 more than second-place seller. How much will each of the top three sellers receive if the profit portion they will share is $200?
Answer:
Profit shall be distributed as :
First seller = $92
Second seller = $72
Third seller = $36
Step-by-step explanation:
Let the first seller be A
Second seller be B
Third seller be C
Let the profit of third price seller C = "x"
Profit of B = 2x
Profit of A = 2x + $20
Total profit received by all of them = $200
$200 = (2x + $20) + (2x) + (x)
$200 = 5x + $20
$180 = 5x
x = $36
Therefore profit for 3rd seller = $36
Profit for second seller = $36 [tex]\times[/tex] 2 = $72
Profit for first seller = $72 + $20 = $92
