Answer:
9x-(x-3) = 2x - (-5 + x)
Step-by-step explanation:
Let's say blank is the variable a.
9x-(x-3) = 2x - (a + x)
Simplify the equation:
9x-(x-3) = 2x - ( a + x)
9x - x + 3 = 2x - a - x
8x + 3 = x - a
7x + 3 = -a
a = -7x - 3
Plug in -5 for x:
a = -7*-5 - 3 = 35 - 3 = 32
a = 32 so the equation with one solution of x = -5 would
9x-(x-3) = 2x - (-5 + x)

Answer:
10/8 or 1.25
Step-by-step explanation:
We can write this into an equation to help us understand what we need.
3/4=0.60x
We can make these both into fractions to make it easier.
3/4=6/10x
Divide both sides by 6/10, or multiply both sides by 10/6.
3/4×10/6=30/24=10/8=1.25
10/8=x

f(x)=-2/9x1/3 what is the intercept
Answer:
1/3
Step-by-step explanation:
Answer:
1/3
Step-by-step explanation: because the equation is in the format f(x)= mx+b and mx represents slope and b represents y. 2/9x is the slope so 1/3 is the y intercept (can i have brainliest)

Step-by-step explanation:
Exercise 1.6 introduces a study on the relationship between socio-economic class and unethical behavior. As part of this study 129 University of (California Berkeley undergraduates were asked to identify themselves as having low or high social-class by comparing themselves to others with the most (least) money, most (least) education, and most (least) respected jobs. They were also presented with a jar of individually wrapped candies and informed that the candies were for children in a nearby laboratory, but that they could take some if they wanted. After completing some unrelated tasks, participants reported the number of candies they had taken. It was found that those who were identified as upper-class took more candy than others.
A. Identify the population of interest and the sample in this study.
B. Comment on whether or not the results of the study can be generalized to the population, and if the findings of the study can be used to establish causal relationships.
Answer:
(A) Population: UCB undergraduates
Sample: The selected 129 UCB undergraduates
(B) Yes, they can be generalized to the population
No, the findings of this single study cannot be used to establish causal relationships between socio-economic classes and unethical behaviors.
Step-by-step explanation:
STUDY: Relationship between socio-economic class and unethical behavior.
The bases for determining social class here are: money, education, and respected job.
RESULT: Those who identified as upper class took more candy than others.
(A) Identify the population of interest and the sample, in this study.
The population of interest in this study is UCB undergraduates.
The sample in this study is the 129 UCB undergraduates who were selected and who agreed to take part in the experiment. They were the participants who were divided into the two social classes before the experiment was conducted.
(B) The results of the study can be generalized to the population of UCB undergraduates since it's likely that the results would be same in another group of 129 UCB undergraduates.
The findings or results of the study cannot be used to establish causal relationships unless the study is conducted in more universities and majority of the results are same with this.
You need to know the number of different arrangements possible for five distinct letters. You decide to use the permutations rule, but your friends tells you to use 5!. Who is correct
Answer:
Both, you and your friend, are correct.

Enter your answers in the boxes to complete the area model.
Answer:
200 + 28= 228
..................
The values of the numbers in the boxes is 57 x 4 = 200 + 28 = 228
Given data ,
Let the equation be represented as A
Now , the value of A is
Let the first number be represented as p
where the value of p = 57
Let the second number be represented as q
where the value of q = 4
And , A = 57 x 4
where the blank spaces in the boxes are by distributive property and
A = 57 x 4
( 50 + 7 ) 4 = ( 50 x 4 ) + ( 7 x 4 )
On simplifying the equation , we get
A = 200 + 28
A = 228
Therefore , the value of A is 228
Hence , the expression is A = 228

Sydney simplifies the expression 2csc(-y) with the work below. What did she do wrong? 2csc(x+y)= 2/sin(x-y)
=2/cos x cos(-y)+sin xsin(-y)
=2/cos x cos y - sin xsin y
=2/cos( x +y)
= 2 sec (x + y)
Answer:
We know that:
csc(x) = 1/sin(x)
Now we want to work with:
2csc(x+y)
The first step is:
2csc(x+y)= 2/sin(x-y)
This is correct so far.
Now we need to use the relation:
sin(a + b) = sin(a)*cos(b) + sin(b)*cos(a)
Then:
sin(x - y) = sin(x)*cos(-y) + sin(-y)*cos(x)
sin(x) is an odd function, then: sin(-y) = -sin(y)
and cos(x) is an even function, then:
cos(-y) = cos(y)
Then we get:
sin(x - y) = sin(x)*cos(y) - sin(y)*cos(x)
then:
2/sin(x-y) = 2/(sin(x)*cos(y) - sin(y)*cos(x))
Now let's look at what she did:
2/sin(x-y) = 2/(cos x cos(-y)+sin xsin(-y))
Here is her error, she replaced:
sin(x - y) by cos x cos(-y)+sin(x)sin(-y)
This relation is for the cosine function, not the sine one, so here is her mistake.
Answer:
[tex]sin(\alpha -\beta )\neq cos \alpha[/tex] [tex]cos\beta +sin\alpha[/tex] [tex]sin\beta[/tex]

Find the equation of a line perpendicular to y=-3x-1 that contains the point (-1,1). Write the equation in slope intercept form.
Answer:
y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]
Step-by-step explanation:
y = -3x - 1
1. Perpendicular line needs the opposite (reciprocal) of the slope.
reciprocal of -3 is -1/3, slope 1/3. y = 1/3x + b
2. Now find the b (y-intercept). 1 = 1/3(-1) + b
1 = -1/3 + b
+ 1/3 +1/3
1 1/3 = b
3. Answer y = [tex]\frac{1}{3}[/tex]x + 1 [tex]\frac{1}{3}[/tex]
A second airline is conducting the same research about its planes, but this company is much bigger and has acquired data for 50 planes. Is a dot plot still beneficial to summarize the data?
Answer:
While it’s possible to create a dot plot using this data, plotting 50 points on a number line is cumbersome. The more data points there are, the more tedious it is to make a dot plot. For this case, it might be better to use a different visual representation.

-3x-4=20
what does x equal?
Answer:
8
Step-by-step explanation:
3x8=24-4=20
Hope this helps!
Answer:
Look down below!
Step-by-step explanation:
Alright, so let's start solving this
1. First we are going to be placing the x one one side and the constants (or the regular numbers) on the other side.
How to do that?
Well, we can take -3x and 20 to their other sides.
The reason for this is that we don't want to have the value with x as a negative
So we do
-3x-4 = 20
+3x -20 -20+3x
You may not understand what was about but all I did was just added 3x to both sides and subtracted 20 to both sides to make the new equation
-24 = 3x or 3x = -24
Now we can see that the x has a number it is being multiplied with so to get rid of the number we divide everything by 3
So
3x/3 = -24/3
Which results in x = -8 and voila, there is your answer!
