Subtract 3 from 12 to get 9.
x>9
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.

Answer:
D
Step-by-step explanation:
First of all, she wants to INCREASE her steps per day. A, B, and C all have the same number of steps or fewer steps. I can further prove that the answer is D because if she stars walking 10 extra steps per day, 10 times 100 = 1000 and 5000 + 1000=6000.

Answer:
[tex] \sqrt{12} [/tex]
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.

During a typing test , bob typed 40 words in 2/3 of a minute what is bobs typing speed.
Work Shown:
40 words = (2/3) of a minute
3*40 words = 3*(2/3) of a minute ... multiply both sides by 3
120 words = 2 minutes
120/2 words = 2/2 minutes .... divide both sides by 2
60 words = 1 minute
Bob's speed is 60 words per minute (wpm)

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]
HELP ME PLEASE!!!! explain how to solve y^4-81/y-3
Answer:
If solved by using quadratic formula, you would need to solve the rational equation by combining expressions and isolating the variable y .
y ≈ 2.45043159
Step-by-step explanation:
The expression (y⁴ - 81) / (y - 3) simplifies to (y + 3)(y² + 9) after factoring and canceling common terms.
expression (y⁴ - 81) / (y - 3)
by simplification
factoring the numerator
y⁴ - 81 = (y²)² - 9² = (y² - 9)(y² + 9)
factoring the denominator
y - 3
we get, (y² - 9)(y² + 9) / (y - 3)
simplifying
(y² - 9) = (y - 3)(y + 3)
(y - 3)(y + 3)(y² + 9) / (y - 3)
(y + 3)(y² + 9)

Answer:
[tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Answer:
(4)
Step-by-step explanation:
The equation of a line in slope- intercept form is

y = - [tex]\frac{2}{3}[/tex] x - 5 ← is in slope- intercept form
with slope m = - [tex]\frac{2}{3}[/tex]

The answer is Graph D.
Step-by-step explanation:
Answer:
D.)
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.

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.
