Answer:
[tex] \huge{ \boxed{ \bold{ \tt{y = - 4}}}}[/tex]
Step-by-step explanation:
[tex] \sf{4y - 9 - 6y = 2(y + 5) - 3}[/tex]
Subtract like terms : 6y from 4y
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2(y + 5) - 3}}[/tex]
Distribute 2 through the parentheses
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2 *y + 2 *5 \: - 3}}[/tex]
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2y + 10 - 3}}[/tex]
Subtract 3 from 10
[tex] \longrightarrow{ \sf{ - 2y - 9 = 2y + 7}}[/tex]
Move 2y to left hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 2y - 2y - 9 = 7}}[/tex]
Move 9 to right hand side and change it's sign
[tex] \longrightarrow{ \sf{ - 2y - 2y = 7 + 9}}[/tex]
Combine like terms
[tex] \longrightarrow{ \sf{ - 4y =7 + 9}}[/tex]
Add the numbers : 7 and 9
[tex] \longrightarrow{ \sf{ - 4y = 16}}[/tex]
Divide both sides by -4
[tex] \longrightarrow{ \sf{ \frac{ - 4y}{ - 4} = \frac{16}{ - 4}}} [/tex]
Remember : Dividing a positive integer by any negative integer gives a negative integer.
[tex] \longrightarrow{ \boxed{ \sf{y = - 4}}}[/tex]
------------------------------------------------------------
Let's check whether the value of y is -4 or not.
VerificationL.H.S : [tex] \sf{4y - 9 - 6y}[/tex]
plug the value of y and simplify
[tex] \dashrightarrow{ \sf{4 * (- 4 )- 9 - 6 * (- 4)}}[/tex]
[tex] \dashrightarrow{ \sf{ - 16 - 9 - ( - 24)}}[/tex]
[tex] \dashrightarrow{ \sf{ - 16 - 9 + 24}}[/tex]
[tex] \dashrightarrow{ \sf{ - 16 + 15}}[/tex]
[tex] \dashrightarrow{ \sf{ - 1}}[/tex]
R.H.S :[tex] \sf{2(y + 5) - 3}[/tex]
plug the value of y and simplify
[tex] \dashrightarrow{ \sf{2( - 4 + 5) - 3}}[/tex]
[tex] \dashrightarrow{ \sf{2 *1 - 3}}[/tex]
[tex] \dashrightarrow{ \sf{2 - 3 }}[/tex]
[tex] \dashrightarrow{ \sf{ - 1}}[/tex]
∴ L.H.S = R.H.S
The value of y is -4
And we're done!
------------------------------------------------------------
Rules for solving an equationIf any equation contains fractions , multiply each term by the LCM of denominators.Remove the brackets , if any.Collect the terms with the variable to left hand side and constant terms to the right side by changing their signs ' + ' into ' - ' and ' - ' into ' + '.Simplify and get the single term on each side.Divide each side by the coefficient of variable and then get the value of variable.Hope I helped!

Answer:
1 (square root of 72)
Step-by-step explanation:
Ok. You can solve this using the pythagorean thereom. This is because AB is the hypotenuse of a right triangle. Therefore, you can solve this problem by using the square of both sides to find the length of the hypotenuse. 6^2+6^2=c^2.
36+36=72
[tex]\sqrt 72[/tex]=8.5
8.5 is about what the line looks to be just by eyeing it, and it fits in with the theroem used, therefore I'd say it is #1. Hope that helps.

whats the slope of 10x+4y=-20
Answer:
In Explanation
Step-by-step explanation:
First, you should put the equation in slope intercept form (y = mx + b), where m is the slope.
10x + 4y = 20
Isolate the y term
10x + 4y – 10x = 20 – 10x
4y = 20 – 10x
Rearrange the terms
4y = –10x + 20
Divide both sides by 4
4y4=−10x+204
y=−104x+5
The slope of the given line is –10/4. A perpendicular line will have a slope with the opposite reciprocal. In simpler terms, you flip the slope and change the sign, therefore, the opposite reciprocal is 4/10.
20 points! Which expression can go in the blank to make the equation true?

Grant is buying a pack of blue and white socks. 4 of the pairs are blue and 6 of the pairs are white. What fraction is equivalent to the portion of socks that are NOT white? Question 4 options: 2/5 3/4 3/5 1/2
Answer:
[tex]Fraction = \frac{2}{5}[/tex]
Step-by-step explanation:
Given
[tex]Blue = 4[/tex]
[tex]White = 6[/tex]
Required
Determine the fraction that are not white
First, we need to determine the total
[tex]Total = Blue + White[/tex]
[tex]Total = 4 + 6[/tex]
[tex]Total = 10[/tex]
Not white, in this case means blue.
So, the fraction is calculated as thus:
[tex]Fraction = \frac{Not\ White}{Total}[/tex]
[tex]Fraction = \frac{Blue}{Total}[/tex]
[tex]Fraction = \frac{4}{10}[/tex]
Simplify
[tex]Fraction = \frac{2}{5}[/tex]
Hence the fraction that are not white is
[tex]Fraction = \frac{2}{5}[/tex]

Step-by-step explanation:
D is the correct answer because it is the only line with a linear function that will forever increase and/or decrease. If the graph has a point using the same y-value assigned to the same x-value more than one time then it is not a function. A graph is only a function if each x-value HAS ONLY ONE y-value.

Which equation represents the line that is perpendicular to y= 1/6 and passes through (-8,-2)?
We want to find a line that is perpendicular to y = 1/6 and that passes through (-8, -2), that line will be x = -8.
Working with perpendicular linesSo we want to get a line, we know it must be perpendicular to y = 1/6.
Notice that y = 1/6 is a horizontal line, then our line must be vertical, this means that our line is something like x = constant.
Now if we want our line to pass through the point (-8, -2), the constant must be equal to the x-value of the point, this is:
x = constant = -8
x = -8
This is the equation of the line perpendicular to y = 1/6 and that passes through (-8, -2)

Randy collected two different data sets and labeled them data set Q and data set R. Data set Q has a correlation coefficient of −0.87,
and data set R has a correlation coefficient of −0.96.
Part A: Which data set has a stronger linear relationship?
Part B: How do you know this?
Select two answers, one for Part A and one for Part B
Answer:
Part A: Data set R
Part B: The correlation coefficient ranges from -1 to 1, where -1 represents a strong negative correlation and 1 represents a strong positive correlation. Data set R has a correlation coefficient of -.96, which has an absolute value that is closer to 1 than Data set Q's -.87, which means that it has a stronger linear relationship.
The data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
We have:
Correlation coefficient for data set Q = -0.87
Correlation coefficient for data set R = -0.96
The data set R has a stronger linear relationship because the value of correlation coefficient is -0.96 which is close to -1.
As we know the correlation coefficient varies between -1 to +1 when the value of correlation coefficient is close to -1 or +1 the relationship is strong.
Thus, the data set R has a stronger linear relationship because the value of correlation coefficient is close to -1.
