Answer: 7 bundles.
Step-by-step explanation:
The cost per bundle is $75.
The cost for shipping is $42.50
She spent $567.50 in total.
The shipping is paid only one time, as all the bundles can be packaged togheter.
Then after paying the shipping, the left spent is:
$567.50 - $42.50 = $525
And each bundle costs $75, then the number of bundles that she bought will be equal to the number of times that we have $75 in $525. This is equal to the quotient between $525 and $75.
N = $525/$75 = 7
She bought 7 bundles

A side of the triangle below has been extended to form an exterior angle of 132°. Find the value of X
Answer:
x = 114°
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
The value of angle x in the triangle will be equal to 114°.
What is an exterior angle?When one side of a triangle is extended, an external angle of the triangle is created. The external angle of the triangle is the non-straight angle (the one that is not simply the extension of the side) that is outside the triangle but close to an interior angle.
Given that a side of the triangle below has been extended to form an exterior angle of 132°
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles, thus
x + 18° = 132° ( subtract 18° from both sides )
x = 114°
Therefore, the value of angle x in the triangle will be equal to 114°.

Consider these functions: f(x)= -2x - 1 g(x)= -1/2x + 1/2 Which statements, if any, are true about these functions? I. The function f(g(x)) = x for all real x. II. The function g(f(x)) = x for all real x. III. Functions f and g are inverse functions. A. I only B. II only C. I, II, and III D. None of the statements are true.
Answer:
A. I only
Step-by-step explanation:
Given the functions
h(x)= -2x - 1 g(x)= -1/2x + 1/2
h(g(x) =h( -1/2x + 1/2)
=f((-x+1)/2)
We are to replace x in h(x) with -x+1/2
h((-x+1)/2) = -2(-x+1)/2 + 1
h((-x+1)/2) = -(-x+1)+1
h((-x+1)/2)= x-1+1
h((-x+1)/2) = x
h(g(x) = x
Also for g(h(x))
g(h(x)) = g(-2x-1)
Since g(x) = -x+1/2
g(-2x-1) = -(-2x-1)+1/2
g(-2x-1) =2x+1+1/2
g(-2x-1) = 2x+2/2
g(-2x-1) = 2(x+1)/2
g(-2x-1) = x+1
Sine g(h(x)) ≠ h(g(x)), hence both functions are not inverses of each other
Hence I. The function h(g(x)) = x is the only correct option. Option A is correct
The correct option is: A. I only
We have functions:
[tex]h(x)= -2x - 1 \\g(x)= -\frac{1}{2} x +\frac{1}{2} \\h(g(x)) =h(-\frac{1}{2} x +\frac{1}{2}) \\h(g(x))=f(\frac{-x+1}{2} )[/tex]
Now, replace x in h(x) by [tex]\frac{-x+1}{2}[/tex]
So,
[tex]h(\frac{-x+1}{2} ) = -2(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} ) = -(\frac{-x+1}{2}) + 1\\h(\frac{-x+1}{2} )= x-1+1\\h(\frac{-x+1}{2} )=x\\h(g(x)) = x[/tex]
Now, g(h(x))
g(h(x)) = g(-2x-1)
Since [tex]g(x) = \frac{-x+1}{2}[/tex]
[tex]g(-2x-1) = \frac{-(-2x-1)+1}{2} \\g(-2x-1) =\frac{2x+1+1}{2}\\g(-2x-1) =\frac{2x+2}{2}\\g(-2x-1) = x+1[/tex]
As g(h(x)) ≠ h(g(x)),
Therefore, both functions are not inverses of each other.
Hence A. I only
The function h(g(x)) = x is the only correct option.
So, option A is correct.

What is function?Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable.
here, we have,
f(x) = 2(3^x)
Exponential functions are those with the following equation:
y = a*b^x
where a ≠ 0, b > 0 and b ≠ 1 and x is a real number.
a is the y-intercept and b is the base.
The initial value of the function is the same as the y-intercept
If a is positive, the function growth. If a is negative, the function decay
Hence, The initial value of the function is 2

What is the slope of the line that goes through points (−3,−4) and (−7,16)? please help
Answer:
5
Step-by-step explanation:
slope = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1}}[/tex]
The second y point is 16 and the first is -4, so:
(16) - (-4)
Which can be written as 16 + 4 because a double negative makes a positive. Do the same for the x points, -7 and -3:
(-7) - (-3)
(-7) + (3)
Now solve both of them:
16 + 4 = 20
(-7) + 3 = -4
Remember, the slope formula is y over x, so we still need to put it into the fraction form:
[tex]\frac{20}{-4}[/tex]
You can reduce this to [tex]-\frac{5}{1}[/tex], or 5.
The slope of the line will be "-5".
Given points are:
[tex](x_1,y_1) = (-3,-4)[/tex][tex](x_2,y_2) = (-7,16)[/tex]As we know the formula,
→ Slope, [tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
By substituting the values, we get
[tex]= \frac{16-(-4)}{-7-(-3)}[/tex]
[tex]= \frac{16+4}{-7+3}[/tex]
[tex]= -\frac{20}{4}[/tex]

When converting rational exponents to radical notation, which of the following are correct? Choose all that apply:
1. Numerator of the rational exponent becomes index of the radical notation
2. Negative exponent of the rational exponent makes the radical notation a negative value
3. Denominator of the radical exponent becomes the power of the radicand in the radical notation
4. Denominator of the rational exponent becomes the index of the radical notation
5. Numerator of the rational exponent becomes power of the radicand in the radical notation
Given:
Converting rational exponents to radical notation.
To find:
The correct statements.
Solution:
According to the property of exponents, conversion of rational exponents to radical notation is
[tex]x^{\frac{a}{b}}=\sqrt[b]{x^a}[/tex]
In [tex]x^\frac{a}{b},[/tex] x is base, a is numerator of the rational exponent and b is denominator of the rational exponent.
In [tex]\sqrt[b]{x^a}[/tex], x is radicand, a is power of radicand and b is index of radical notation.
Denominator of the rational exponent becomes the index of the radical notation.
Numerator of the rational exponent becomes power of the radicand in the radical notation.
Therefore, the correct options are 4 and 5.
Using the conversion of rational exponents to radical notation, it is found that the correct options are:
4. Denominator of the rational exponent becomes the index of the radical notation
5. Numerator of the rational exponent becomes power of the radicand in the radical notation
The conversion of rational exponents to radical notation is modeled by:
[tex]a^{\frac{n}{m}} = \sqrt[m]{a^n}[/tex]
That is:
The numerator becomes the power of the radicand, hence item 5 is correct.The denominator becomes the index of the radical notation, hence item 4 is correct.A negative exponent just is represented by a fraction, as [tex]a^{-\frac{n}{m}} = \frac{1}{a^{\frac{n}{m}}}[/tex], hence the radical is not negative, and item 2 is incorrect.

jamie reads 15 pages in 25 minutes and wants to know how many pages she can read in 65 minutes
Answer:
39
Step-by-step explanation:
15/25 = 0.6 - She can read 0.6 pages in 1 minute.
0.6 X 65 = 39
There are 39 pages she can read in 65 minutes.
What is Proportional?Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.
Given that;
Jamie reads 15 pages in 25 minutes
And, wants to know how many pages she can read in 65 minutes
Now, Let number of pages read in 65 minutes = x
Hence, We can formulate;
x / 65 = 15 / 25
x = 15 x 65 / 25

need help with these 3
Answer:
1.) x = 110
[tex]\frac{3}{22} =\frac{15}{x}[/tex]
So for 3 to become 15 it would have to be multiplied by 5 because 3 x 5 = 15. And if I multiply the numerator by anything I always have to do the same to the denominator. So I multiply 22 x 5 = x. x = 110
[tex]\frac{3 * 5}{22*5} =\frac{15}{110}[/tex]
2.) x = 72
[tex]\frac{x}{16} =\frac{9}{2}[/tex]
For 16 to become 2 it has to be divided by 8 because 16 ÷ 8 = 2. And I have to do the same to the numerator of course, so i have to find x ÷ 8 = 9. I know the answer by memory, but for some it's easier to rewrite this as 9 × 8 = x. x=72
[tex]\frac{72}{16} =\frac{9}{2}[/tex]
3.) c = 24
[tex]\frac{3}{5} =\frac{c}{40}[/tex]
For 5 to become 40 it must be multiplied by 8 because 5 × 8 = 40. I have to multiply 8 by the numerator as well and 3 × 8 = 24. c = 24

What is the Least Common Multiple (LCM) of 3 and 6?
Answer:
6
Step-by-step explanation:
Both numbers can evenly go into 6: 3 can go into 6 two times, and 6 can go into 6 one time.I hope this helps!
The LCM of 3 and 6 is 6, which is the smallest positive integer that is a multiple of both numbers.
What is Least Common Multiple(LCM)?The least common multiple is defined as the least positive integer that is dividable by both given numbers.
A group's Least Common Multiple (LCM) is the smallest number that is a multiple of all the numbers.
We can use the prime factorization method to find the LCM. We can write each number as a product of its prime factors:
3 = 3
6 = 2 x 3
The LCM is the product of the highest powers of all the prime factors.
Here, the highest power of 2 is 2, and the highest power of 3 is 3. So, the LCM is:
LCM(3, 6) = 2 x 3 = 6
Thus, the LCM of 3 and 6 is 6, which is the smallest positive integer that is a multiple of both numbers.
