Answer:
8x·x·x·x·x·x
Step-by-step explanation:
Using the rules of exponents, this simplifies to ...
[tex](2x^2)^3 = 2^3x^{2\cdot3}=8x^6=\boxed{8\cdot x\cdot x\cdot x\cdot x\cdot x\cdot x}[/tex]
__
The applicable rules of exponents are ...
(a^b)^c = a^(bc)
(ab)^c = (a^c)(b^c)
Of course, an exponent signifies repeated multiplication.
What is the solution to the problem below
Consider the function f(x) = 2x^2 - 4x + 9. Evaluate 2f(3) + 3f(-3).
Answer: 147
Step-by-step explanation:
To evaluate 2f(3)+3f(-3), we first need to find the values of f(3) and f(-3). Given f(x), we just plug in x=3, -3 into f(x).
f(3)=2(3)²-4(3)+9 [exponent]
f(3)=2(9)-4(3)+9 [parenthesis]
f(3)=18-12+9 [subtract]
f(3)=6+9 [add]
f(3)=15
Now, we find f(-3).
f(-3)=2(-3)²-4(-3)+9 [exponent]
f(-3)=2(9)-4(-3)+9 [parenthesis]
f(-3)=18+12+9 [add]
f(-3)=30+9 [add]
f(-3)=39
With the values of f(3) and f(-3), we can evaluate the expression.
2(15)+3(39) [multiply]
30+117 [add]
147
Now, we know the value is 147.
A 3-pack of light bulbs costs $3.45. A 4-pack of the same light bulbs costs $4.20.
Which pack has better value?
Answer:
The 4-pack light bulbs
Step-by-step explanation:
Price of a light bulb in 3-pack
= 3.45÷3

Price of a light bulb in 4-pack
= 4.20÷4
= $1.05
HELP ASAP! im really stuck because im dumb and if anyone can help that would be appreciated!
he graph below represents the price of sending video messages using the services of a phone company. What is the constant of proportionality? A graph is shown. The values on the x axis are 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. The values on the y axis are 0, 24, 48, 72, 96, 120, 144, 168, 192, 216, 240. Points are shown on ordered pairs 0, 0 and 2, 48 and 4, 96 and 6, 144 and 8, 192. These points are connected by a line. The label on the x axis is Video Messages Sent. The label on the y axis is Price in cents. 12 24 46 48
Answer:
24.
Step-by-step explanation:
Basically constant of proportionality is a ratio.
We take two points, we'll take the order pair (2,48)
It will always be y/x so y is 48 and x is 2
48/2 - now we simplify
answer: 24
hope this helps! :))

p = q
q = 1
pq = 1
Answer:
p=q
Step-by-step explanation:
for example if your paying 2 dollars for every 1 item the ratio would be 2:1

Help i need answers asap!! there's only a lot of pictures because i waned you to see what i' doing PART !!!!! GO TO MY ACCOUNT AND LOOK AT MY QUESTIONS FOR THE LAST QUESTION
Answer:
The store for b should be $11
Step-by-step explanation:
I would find A for you too but there is no graph! But for example the slope formula is (y2-y1)/(x2-x1)! You would take any big y number and use it as your y2 go up one use it as your y1 subtract it that’s your numerator. Next take your big x2 across from your y2 and then use the one across from y1 and subtract those that’s your denominator!
Three friends are selling items at a bake sale. May makes $23.25 selling bread. Inez sells gift baskets and makes 100 times as much as May. Carolyn sells pies and makes one tenth of the money Inez makes. How much money does each friend make?
May:
Inez:
Carolyn:
Answer:
May = $23.25 Inez = $2325 Carolyn = $232.50
Step-by-step:
May makes that much because it says it in the problem. Inez makes that much because 23.25 times 100 equals 2325. Finally one tenth of 2325 is 232.5
Answer:
may makes 23.25
inez make 2, 325
Carolyn make 232.5

To solve you need to replace the variables with their numbers.
3(-1) - (-1^2)
-1 x -1 = -1
3 x (-1) = -3
-3 - (-1) =
-2
Han wears a hat to school every 4th day and a jacket every 6th day. What will be the first day that Han wears a hat and a jacket on the same day?
Answer:

6 and 4 are multiples of each other. We would need to find the day that they both have the same number like below.
4 , 8 , 12 , 16 , 20 , 24
6 , 12 , 18 , 24
Han would wear a hat and jacket to school on the 24th day.
