the reciprocal will be negative
Answer:
The reciprocal of a negative number must itself be a negative number so that the number and its reciprocal multiply to 1.
The reciprocal of a positive or negative fraction is obtained by switching its numerator and denominator, the sign of the new fraction remains the same. ... Notice that when you multiply negative fractions with their reciprocals, the product is always 1 (NOT -1).
please please help !!! will give brainliest to first correct answer
Answer:
[See Below]
Step-by-step explanation:
❶ It is irrational because to make it repeating it must be EXACT. In this case it is adding a 0 after every 1. So it'd be irrational since it doesn't have an end.
❷ Irrational because no one knows the end of pi. It doesn't have an ending so therefore irrational.

Step-by-step explanation:
slove for x 2x+13=-54
Answer:
x = -33.5
Step-by-step explanation:
2x+13=-54
Subtract 13 from each side
2x+13-13=-54-13
2x = -67
Divide by 2
2x/2 = -67/2
x = -33.5
Answer:
x= -33 1/2 (-33.5)
Step-by-step explanation:
2x+13=-54
2x+13-13=-54-13
2x=-67
x=-67/2
x= -33 1/2 (-33.5)
Which two transformations must be applied to the graph of y = ln(x) to result in the graph of y = –ln(x) + 64?
A) reflection over the x-axis, plus a vertical translation
B) reflection over the y-axis, plus a vertical translation
C) reflection over the x-axis, plus a horizontal translation
D) reflection over the y-axis, plus a horizontal translation
Answer: A) reflection over the x-axis, plus a vertical translation
Step-by-step explanation:
Ok, when we have a function y = f(x)
> A reflection over the x-axis changes a point (x, y) to a point (x, -y), then for a function (x , y = f(x)) the point will change to (x, -y =- f(x))
then for a funtion g(x), this tranformation can be written as h(x) = -g(x).
> A vertical translation of A units (A positive) up for a function g(x) can be written as: h(x) = g(x) + A.
Then in this case we have:
y = g(x) = ln(x)
and the transformed function is h(x) = -ln(x) + 64
Then we can start with h(x) = g(x)
first do a reflection over the x-axis, and now we have:
h(x) = -g(x) = -ln(x)
And now we can do a vertical translation of 64 units up
h(x) = -g(x) + 64 = -ln(x) + 64
Then the correct option is:
A) reflection over the x-axis, plus a vertical translation

What is the mean of the height 81,88,69,65,87
Answer:
C. 78 cm
Step-by-step explanation:
The mean of any given data set is calculated as sum of all data set divided by the number of data set given.
The data set for the height of Bella's corn given, is 81, 88, 69, 65, 87
Mean height of Bella's corn = [tex] \frac{81 + 88 + 69 + 65 + 87}{5} [/tex]
[tex] mean = \frac{390}{5} [/tex]
[tex] mean = 78 cm [/tex]
You are required to calculate the mean of the height, in other words, the average of the height
The mean of the height is 78
Given height
81, 88, 69, 65, 87
Mean = Total height / number of height
= (81 + 88 + 69 + 65 + 87) / 5
= 390 / 5
= 78
Mean of the height = 78

Simplify. Rewrite the expression in the form a^na n a, start superscript, n, end superscript. a^{5}\cdot a^{-3}=a 5 ⋅a −3
Answer:
The expression simplified is a^2
Step-by-step explanation:
Here, we are interested in writing the product as a single value.
We have; a^5 • a^-3
This is same as a^5 * a^-3
We proceed here using the first law of indices;
It would result to a^5 * a^-3 = a^(5-3) = a^2

Studio fee:$8 per hour
Vase:$10
Answer:
4.5 hours
Step-by-step explanation:
So, let's write a function p(x) which represents the total cost.
Let's let x represent the amount of hours.
The cost of a piece is a constant 10.
And there is a $8 fee per hour. In other words:
[tex]p(x)=8x+10[/tex]
We spent a total of $46.
So, substitute in 46 for p(x) and solve for x:
[tex]46=8x+10[/tex]
Subtract 10 from both sides:
[tex]36=8x[/tex]
Divide both sides by 8:
[tex]x=36/8[/tex]
Reduce:
[tex]x=4.5[/tex]
So, we spent about 4.5 hours.

can someone plz help me x-y/2z=3
Answer:
x-y/2z=3
2z(x-y)/2z = 3 × 2z
x-y = 6z
x-y/6 = 6z/6
z = x-y/6
x-y/2z = 3
2z(x-y)/2z = 3 × 2z
x - y = 6z
x-y+y = 6z + y
x = 6z + y
x-y/2z=3
2z(x-y)/2z = 3 × 2z
x-y = 6z
-x + x - y = 6z - x
-y = 6z - x
-y/-1 = 6z - x / -1
y = -6z + x
The expression is written as;
⇒ x = 6z + y
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
We have to given that;
The expression is,
⇒ (x - y) / 2z = 3
Now, Simplify the expression for x as;
⇒ x - y = 3 × 2z
⇒ x - y = 6z
⇒ x = 6z + y
