Given:
The expression is:
[tex]-1(2x+3)-2(x-1)[/tex]
To find:
The simplified form of the given expression.
Solution:
We have,
[tex]-1(2x+3)-2(x-1)[/tex]
Using distributive property, we get
[tex]-1(2x+3)-2(x-1)=-1(2x)-1(3)-2(x)-2(-1)[/tex]
[tex]-1(2x+3)-2(x-1)=-2x-3-2x+2[/tex]
On combining like terms, we get
[tex]-1(2x+3)-2(x-1)=(-2x-2x)+(2-3)[/tex]
[tex]-1(2x+3)-2(x-1)=-4x-1[/tex]
Therefore, the simplified form of the given expression is [tex]-4x-1[/tex].

Ann and Bill share an amount of money in the ratio 7:n
Ann gets 28% of the money.
Work out the value of n
Answer:
48
Step-by-step explanation:
The value of n will be;
⇒ n = 18
What is mean by Ratio?A ratio indicates how many times one number contain in another number. The ratio of two number is written as x : y, which is equivalent to x/y. Where, x and y are individual amount of two quantities. And, Total quantity gives after combine as x + y.
Given that;
Ann and Bill share an amount of money in the ratio = 7 : n
And, Ann gets 28% of the money.
Now,
Since, Ann and Bill share an amount of money in the ratio = 7 : n
And, Ann gets 28% of the money.
Thus, Bill gets the money = 100 - 28%
= 72%
So, The unit ratio for the Ann = 28 / 7
= 4
Hence, Bill ratio will be = 72/4
= 18
Thus, The ratio of an amount of money = 7 : 18
Hence, The value of n = 18.

1. Look at the following correlation scatter plot. What type of a correlation is it?
a. Negative correlation
b. Positive correlation
c. Zero correlation
d. All of the above
Scatter plot is missing, so i have attached it.
Answer:
C : zero correlation
Step-by-step explanation:
A correlation is said to be negative between two variables when they are related in such a manner that when one variable increases, the other variable decreases and vice versa.
However, a correlation is said to be Positive when one variable increases as the other increases as well and vice versa which means they both move in the same direction.
However, in the image of the scatter plot attached, we see that it is neither positive or negative correlation as there is no clear visible relationship between the variables on the x and y axis.
Thus, we can say there is zero correlation.
use what you know about translations of functions to analyze the graph of the function f(x) = (0.5)^x-5+8 you may wish to grab it and its parent function y=0.5^x on the same axes
The parent function y=0.5^x is _____ across its domain because its base b is such that
First box is: decreasing
Second box: 0< b< 1
Third box: Up
Fourth box: Right
The parent function y=0.5^x is decreasing across its domain because its base b is such that (0<b<1) and function shifts it 8 units up and 5 units right.
What is translation of a function?Translation of a function is shifting the function from its original place in the graph.
Types of translation -
Horizontal shift- Let the parent function is f(x). Thus by replacing parent function with f(x-b) shifts the graph b units right and by replacing parent function with f(x+b) shifts the graph b units left.Vertical shift- Let the parent function is f(x). Thus by replacing parent function with f(x)+c shifts the graph c units down and by replacing parent function with f(x)-c shifts the graph b units up.
The functions of the graph given in the problem as,
[tex]f(x) = (0.5)^{x-5}+8[/tex]
The parent function of the graph is,
[tex]y=0.5^x[/tex]
In the parent function, the 5 units subtracted, and 8 units added outside the function. Thus, the function shifts the parent function 8 units up and 5 units right.
Thus, the parent function y=0.5^x is decreasing across its domain because its base b is such that (0<b<1) and function shifts it 8 units up and 5 units right.

What is the length of the arc intercepted by a central angle that measures 3π/4 radians?
Express the answer in terms of π .
Answer:
36π mm
Step-by-step explanation:
The arc length formula is s = rФ, where Ф is the central angle (in radians).
If r = 48 mm and Ф = 3π/4, then the arc length is:
s = rФ = (48 mm)(3π/4) = 36π mm
