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.
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:
He will wear a hat and jacket on the 12th day
Step-by-step explanation:
Answer:
The 24th day
Step-by-step explanation:
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.

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

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!

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! :))

24/3=8
8x8=64
Answer:
She will make $192 for 8 hours.
Step-by-step explanation:
You do 24 times 8 which is 192. 24 x 8 = 192
if a = and b = -1 what is the value of ab -b^2
Answer:

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.
