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.

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!

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.
Which of the following equations is equivalent to 5/8 = 22/x-6?
100 = 8x – 48
5x – 3 = 176
5x – 30 = 176
40 = 30x – 132

On a coordinate plane, the x-axis is labeled bananas and the y-axis is labeled cost in dollars. The line goes through points (1, 0.27) and (2, 0.54).
Which statement about the graph is true?
The number of bananas is the independent variable, and the cost in dollars is the dependent variable.
The point (1.35, 5) is on the line.
The number of bananas is graphed on the y-axis, and the cost is graphed on the x-axis.
The two variables are the number of bananas and the cost of one banana.
Answer:
I think it is A correct me if I am wrong
Step-by-step explanation:
The statement first "The number of bananas is the independent variable, and the cost in dollars is the dependent variable" is correct.
What is a line graph?A line graph is a graph made up of segments of straight lines that connect the depicted data points.
We have:
The line goes through points (1, 0.27) and (2, 0.54).
The x-axis represents the independent variable
The y-axis represents the dependent variable.
Thus, the statement first "The number of bananas is the independent variable, and the cost in dollars is the dependent variable" is correct.

Orlo uses a spool of wire to make 15 necklaces.
At this rate, how many spools of the same size would he use to make 50 necklaces?
he would use to make 50 necklaces 4 spools of the same size.
What is ratio?The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.
Given this, Orlo uses a spool of wire to make 15 necklaces.
Since she requires 15 necklaces = 1 spool of wire
So, requirement for 1 necklace = 1/15 spool of wire
Thus,
requirement of wire for 50 necklace = 50/15 spool of wire
requirement of wire for 50 necklace = 10/3 spool of wire
requirement of wire for 50 necklace = 3.33 spool of wire
Therefore, 4 spools of the same size he would use to make 50 necklaces.
