9. Solve for x: 2x – y = (3/4)x + 6.​
AlekseyPX

Answer:

x = 4(y + 6)/5

Step-by-step explanation:

2x - y = (3/4)x + 6

2x - (3/4)x = y + 6

(8x - 3x)/4 = y + 6

5x/4 = y + 6

5x = 4(y + 6)

5x = 4y + 24

x = (4y + 24)/5

Therefore, x = 4(y + 6)/5

Which r–value represents the strongest negative correlation?<br><br> –0.7<br> –0.22<br> 0.38<br> 0.9
inn [45]

Answer:

Option A is correct.

The value of r = -0.7 represents the strongest negative correlation.

Step-by-step explanation:

A correlation is a  value that describes a relationship between two things  or variables.

Strongest Negative Correlation says that closer a negative correlation to -1, the stronger the relationship between the two variables.

From the options,  we have only two negative values i.e, r= -0.7 and r= -0.22.

We have to find the strongest negative correlation r-value.

By the definition, you can see that -0.7 is very closer to -1 ,

therefore, the  value of r = -0.7 represents the strongest negative correlation.

SVETLANKA909090 [29]
Starting January 1, 2015, there are 364 remaining nights.
From 1,001 nights, it will be 637 nights left.

In 2016, there are 366 nights. Subtract it to 637 nights left, you will get 271 nights left.
In 2017, 271 is lesser than 365.
From January to August, the nights left is 28.

An animal shelter spends three dollars per day to take care for each bird and seven dollars per day take care for each cat Alexa
NikAS [45]

Answer:

There were 16 birds  at the shelter on Wednesday.

Step-by-step explanation:

Number of cats and birds on Wednesday = 34

let the number of birds on Wednesday = b

Then number of cats = (34 -b)

The rate of taking care of each bird in shelter = $3

The rate of taking care of each cat in shelter = $7

Total amount spent by shelter on Wednesday = $174

So, according to the question

b x ($3)  +  (34 -b) ($7) =  $ 174

or,  3b + 238 - 7b = 174

or, 4b = 64

⇒ b = 64/4 = 16

Hence, the number of birds in shelter on Wednesday = b = 16

and  Number of cats = 34 - 16 = 18
