Answer:
y=-4
Step-by-step explanation:
Distribute:
−2+12+14=9
Add the Numbers:
12+12=9
Rearange the Terms:
12+12=9
Subtract 12 from both sides:
12+12−12=9−12
12=9−12
Subtract 9y from both sides:
12−9=9−12−9
3=−12
Divide both sides of the equation by the same term:
3y/3=12/3

What is the percent of change from 8,000 to 80?
Answer:
-99%
Step-by-step explanation:
Since it is going down, it'll be negative.
8,000 - 80 = 7,920
7,920 / 8,000 = 0.99
0.99 x 100 = 99%
-99%
(they might be asking for just 99% though too!)

Jesse takes two data points from the weight and feed cost data set to calculate a slope, or average rate of change. A hamster weighs half a pound and costs $2 per week to feed, while a Labrador Retriever weighs 62.5 pounds and costs $10 per week to feed.
Using weight as the explanatory variable, what is the slope of a line between these two points? Answer choices are rounded to the nearest hundredth.
Answer:
$0.13 per lb
Step-by-step explanation:
The slope of a line between these two points is 0.13.
What is Slope of Line?The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.
The slope intercept form of a line is y=mx+b, where m is slope and b is the y intercept.
The slope of line passing through two points (x₁, y₁) and (x₂, y₂) is
m=y₂-y₁/x₂-x₁
Given that A hamster weighs half a pound and costs $2 per week to feed.
Labrador Retriever weighs 62.5 pounds and costs $10 per week to feed.
Let x be the weigh and y be the feed cost.
The two points of lines are (0.5, 2) and (62.5, 10)
m=10-2/62.5-0.5
m=0.13
Hence, the slope of a line between these two points is 0.13.

2x - 3y = 10
6y = 4x - 20
Answer:
(5,0)
Step-by-step explanation:
Switch the second equation around so it matches up with the first one :
4x-6y = 20
Then solve by elimination :
-2 (2x-3y = 10) = -4x+6y = -20
-4x+3y = -20
+ 4x-6y = 20
--------------------
-3y = 0
y = 0
Plug y as 0 into one equation :
2x-3(0) = 10
2x = 10
x = 5
Your solution would be (5,0) .

f(m)=m^5+3m^4-21m^3-12m^3-12m^2=31m-33 at m=6
Answer:
False
or
3951
Step-by-step explanation:
F(m) represents an equation that when the "m" is changed within the parenthesis, all the m's in the equation change as well. The function determines the value of the equation.
In this case, "m = 6" or in basic terms:
f(6) = m^5 + 3m^4 - 21m^3 - 12m^3 - 12m^2 = 31m - 33
Replace all m's with 6.
[tex]f(6) = (6)^5 + 3(6)^4 - 21(6)^3 - 12(6)^3 - 12(6)^2 = 31(6) - 33[/tex]
And do the exponents + coefficients.
6^5 = 7776
3(6^4) = 3888
-21(6)^3 = -4536
-12(6)^3 = -2592
-12(6)^2 = -432
31(6) = 186
-33 = -33
Our final equation is:
7776 + 3888 - 4536 - 2592 - 432 = 186 - 33
Add/subtract all together:
4104 = 153
Now because of your question being quite vague, there could be two ways of answering.
One: Determining whether the equation is true or false, which in this case. 4104 does indeed not equal 153, therefore making it false.
Two: Getting one single number, which we would have to subtract 153 from both sides to get the answer:
4104 - 153 = 153 - 153

The measure of angle e is?
Answer:
49 degrees
Step-by-step explanation:
Answer:
m<E = 49°
Step-by-step explanation:
Using the straight angle theorem, we can add the angles measuring 63, 68, and the angle above the 68(let's call it x) add to 180. We can write an equation:
63 + 68 + x = 180
This means:
x = 49
Angle x is alternate interior to angle E, meaning the two are congruent and have the same measure. This means m<E = 49

Answer:

Step-by-step explanation:
Use the scatter plot and regression line shown below to answer the questions.
(a) Describe the association if any, between the variables.
(b) Estimate the correlation coefficient (r) between the variables.
(c) The points (7,28) and (9,33) are one the regression. Find the slope of the regression line (show all your work)
(d) Determine the equation of the regression line (show all your work)
(e) Estimate the value of y if x=25 (show all your work)
The relationship between the x and y variables in the scatter plot is
approximately linear.
(a) Increase in the y-variable follows from an increase in the x-variable
(b) The regression coefficient is approximately 0.9465
(c) The slope of the regression line is 2.5
(d) The equation of the regression line is approximately; y = 2.5·x + 10.5
(e) If x = 25, the value of y is 73
Reasons:
(a) From the attached graph, we have;
The increase in the x-variable gives a corresponding increase in the y-
variable.
(b) The correlation coefficient is given by plotting the given points using
MS Excel and finding the regression line, from which we have;
The regression coefficient is R ≈ √(0.8958) ≈ 0.9465
(c) The slope of the regression line is given by the slope of the line with
points (7, 28), and (9, 33), as follows;
[tex]Slope = \dfrac{33 - 28}{9 - 7} = 2.5[/tex]
The slope of the regression line is approximately 2.5
(d) Using the slope, m = 2.5, we get;
Equation of regression line, is y - 33 = 2.5·(x - 9)
Which gives;
y - 33 = 2.5·(x - 9) = 2.5·x - 22.5
y = 2.5·x - 22.5 + 33 =
The equation of the line is; y = 2.5·x + 10.5
(e) If x = 25, we have;
y = 2.5 × 25 + 10.5 = 73
Therefore, if x = 25, y = 73
