$4.99 for 6 cans or $7.99 for 10 cans?
Answer:
$7.99 for 10 cans
Step-by-step explanation:
First you want to see what the price is for one can. Do this by dividing 6 from 4.99 (4.99/6). This gives you 83 cents per can. Do the same for the other, and you get 79 cents per can. 79 cents is a better value than 83 cents.

Functions I need help with 14-17
Answer:
14) No. 15) No. 16) Yes. 17) Yes.
Explanation:
When something is not a function, you can either use the vertical line test which involves drawing a line going up and down to see if the graph hits the line more than once. If this is the case, it is not a function. Or the input or x value of a function cannot have more than one
output or y value.
The line x = |y| on the graph of #14 is not a function because there is more than one y value for a single x value. This also hits a vertical line more than once.
The table on #15 is not a function because their is more than one y value per x value. It also hits a vertical line more than once.
The equation y = 1/4x is a function because there is only one output for each input. This also does not hit a vertical line more than once
The equation x = y - 1 is a function because it is simply a rearanged version of y = x + 1 which has only one output for each input. It also does not hit a vertical line more than once.
Are 4/7 and 12/21 equivalent fractions? Why or why not?
Answer:
Yes
Step-by-step explanation:
12/21 simplified is 4/7. if you divide the numerator (12) by 3 and the denominator (21) by 3, you get 4 and 7, or 4/7 if you put it together.
4/7 and 12/21 are equivalent fractions
What is Fraction?A fraction represents a part of a whole.
We need to check whether the fractions 4/7 and 12/21 are equivalent or not.
Equivalent fractions are the fractions that have different numerators and denominators but are equal to the same value.
12/21 we have to simplify.
12 and 21 are the multiples of 3, so divide numerator and denominator by 3
which gives 4/7
12/21=4/7
Hence, 4/7 and 12/21 are equivalent fractions

Each day, a zoo sells 8400 special admission passes to visitors. The passes allow these visitors to enter the park early. The number of visitors who pay the normal entry fee has been decreasing by 7% each day. Today, 56,000 visitors paid the normal entry fee. Which function represents what the total number of visitors to the zoo will be after x days?
A. f(x)=56,000(0.93)x+8400
B. f(x)=56,000(0.93)x
C. f(x)=56,000(0.07)x
D. f(x)=56,000(0.07)x+8400
9514 1404 393
Answer:
A. f(x)=56,000(0.93)x+8400
Step-by-step explanation:
The growth rate is -7%, so the growth factor will be 1 -7% = 0.93. This is the base of the exponential term.
The 8400 special passes will add 8400 visitors to the park in addition to those who pay the regular fee. Thus the number of visitors is ...
f(x) = 56,000(0.93^x) +8400 . . . . matches choice A
Write the slope-intercept form of the given line. Include your work in your final answer.
Answer:
[tex]y=-\frac{1}{3}x+1[/tex]
Step-by-step explanation:
Let the equation of the line is,
y = mx + b
Where 'm' = slope of the line
b = y-intercept
From the picture attached,
b = 1
Slope of the line passing through two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is represented by,
m = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
Slope of the line passing through the points (0, 1) and (3, 0) will be,
m = [tex]\frac{0-1}{3-0}[/tex] = [tex]-\frac{1}{3}[/tex]
Equation of the line will be,

The quotient of a number and -5 has a result of 2. What is the number?
Type the correct answer in the box. Use numerals instead of words.
n =
Answer:
Answer is -10
Step-by-step explanation:
Explanation:
First, define the variable. Let n represent the unknown number.
Next, write an equation to represent the situation. Because a quotient is the result of division, divide the unknown number by -5:
.
Then, use opposite operations and the properties of equality to solve for n. Notice that the variable, n, is divided by -5. So, to isolate n, do the opposite and multiply both sides of the equation by -5:
Finally, to check the solution, substitute -10 for n in the original equation:
The resulting statement is true, so the solution is correct.

given the following functions, find and simplify (f−g)(x).
f(x)g(x)=−2x2+2x+3=−4
Answer: (F-G)(x)=5x2+2i +1
Step-by-step explanation
The resulting function for (f−g)(x) is 2x²+x-3
Let the required functions be:
f(x)=2x²+3x
g(x)=2x+3
We are required to find (f−g)(x).
(f−g)(x). = f(x) - g(x)
(f−g)(x) = 2x²+3x - (2x+3)
(f−g)(x) = 2x²+3x - 2x - 3
(f−g)(x) = 2x²+x-3
Hence the resulting function for (f−g)(x) is 2x²+x-3

There is one complex imaginary root.
There are two real roots.
Answer:

A discriminate of -8 is never going to give you a real root. D is wrong
You cannot have just 1 complex root, nor can you have just 1 real root unless the discriminate is 0. A and C are both wrong for the same reason. 1 complex root is impossible. They come in pairs.

Answer:
A) [tex]5x-1=-6[/tex]
B) [tex]x=-1[/tex]
Step-by-step explanation:
On the left, we have five (positive) Xs and one -1. So, we can represent the left with the expression [tex]5x-1[/tex].
On the right, we have six -1s. So, we can represent the right with the expression [tex]-6[/tex].
A)
Since the balance is balanced, we know that the two expressions are equal to each other. So, we can write the equation:
[tex]5x-1=-6[/tex]
B)
Now, we can solve the equation for x. Add 1 to both sides:
[tex](5x-1)+1=(-6)+1[/tex]
The left will cancel. Add on the right:
[tex]5x=-5[/tex]
Finally, divide both sides by 5:
[tex](5x)/5=(-5)/5[/tex]
The left side will cancel. So, the value of x is:
[tex]x=-1[/tex]

A) 5x-1=-6

Both are 123
When dealing with angles you have to remember that all angles add up to 180, “the line angle” as I like to call it, it’s because 180 is completely flat.
2: Here you can use your eyes to see the angle is wider than 90, ”a perfect right”. So you can easily assume that the angle is gonna be 123.
1: the angle here shares the same place as your original angle. So you can easily assume that they have the same degree

Answer:
[tex]Vc = 2,261.9\ in^3[/tex]
Step-by-step explanation:
Volume of a Cylinder
The volume of a cylinder of radius r in and a height h can be calculated by:
[tex]Vc=\pi\cdot r^2\cdot h[/tex]
The height of the cylinder is h = 20 in and the base radius is r = 6 in, thus:
[tex]Vc=\pi\cdot 6^2\cdot 20[/tex]
[tex]Vc = 2,261.9\ in^3[/tex]
