Create an equation with one solution of x = −5.
9x − (x − 3) = 2x − (__ + x)
7.4 #7

Answers

Answer 1

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)

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.

Use elimination to solve the system
2x-y=10
8x+y=20
Please someone help I need help so bad I’m so scared I’m gonna fail this test I may get held back if I fail this test please help me

Answers

Use elimination to cancel y. Add both systems together:
2x + 8x - y + y = 10 + 20

Combine like terms:
10x = 30

Divide by 10:
x = 3

Plug x back in to solve for y:
2(3) - y = 10
6 - y = 10

Subtract 6:
-y = 4

Divide by -1:
y = -4


So your solution is x = 3 and y = -4 which is also written as (3, -4).

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.

Answers

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.

What is 57 x 4?
Enter your answers in the boxes to complete the area model.

Answers

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)​

Answers

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.

Find the equation of a line perpendicular to y=-3x-1 that contains the point (-1,1). Write the equation in slope intercept form.

Answers

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

what does x equal?

Answers

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!

The price listed for 4 dinner plates at a home store is $23.88. What amount will Jane need to pay, if she decides to purchase 10 such dinner plates?

Answers

If you want to answer this, then you’ll first have to figure out how much money the one plate costs. So you would divide $23.88 by 4 and the number you get is how much they paid for one plate.

Next you would have to take the number you get from the division problem and multiply that by 10. That will give you your answer for how much she will need to pay.

Work:
$23.88 / 4 = 5.97
5.97 x 10 = 59.70

She needs to pay $59.70 for the plates.
