Answer:
slope = 4/1 or 4
Step-by-step explanation:
Answer: 4
Step-by-step explanation:
Use the slope formula. change in y/change in x. The change in y is 4 because if your subtract the y coordinate 4 from the y coordinate 8, you get 4. The change in x is 1 because if you subtract the x coordinate 2 from the x coordinate 3, you get 1. 4 (change in y)/1 (change in x) is 4. Hope this helps!

It is the end of the semester, and the clubs at school are recording their profits. The Science Club started out with $20 and has increased its balance by an average of $10 per week. Write an equation in slope intercept form for the Science Club. It is the end of the semester, and the clubs at school are recording their profits. The Math Club has saved $5 per week after starting out with $50 at the beginning of the semester. Write an equation in slope intercept form for the Math Club. It is the end of the semester, and the clubs at school are recording their profits. Graph both lines from question 1 and 2 on the same coordinate plane. When do the clubs have the same balance?
Answers
Answer:
Science Club- y=10x+20
Math Club- y=5x+50
They will be equal 6 weeks
Step-by-step explanation:
X equals the number of weeks that have passed. In example of the science club, they would gain $10 every week, making the equation y (total money) equal to 10 dollars a week (or 10x.)
Since we know they begin with 20 dollars, we'll simply add that to the 10 dollars a week.
To find the week when they will be equal, we have to put both equations equal to each other.
10x+20=5x+50
Now we solve for x, or the number of weeks when the equations (and values) will be equal.
10x+20=5x+50
5x+20=50
5x=30
x=6
So... 6 weeks :)

The linear regression equation model obtained from the online regression equation is :
y = 0.75x + 5 ; where ;
y = weekly sales ; x = test score ; 0.75 = slope / gradient ; 5 = intercept
sales if the test score of a salesman is 65.
y = 0.75x + 5
x = 65
y = 0.75(65) + 5
y = 48.75 + 5
y = 53.75

Divide 5 liters in the ratio 11:5:9. Give your answer in milliters.
Answers
Answer: we have 2,200milliters, 1000milliters, 1800milliters.
Step-by-step explanation:
Step 1
1 Liter= 1000 millilitres
5 liters = 5000 millilitres
Step 2
Dividing 5000 ml in the ratio 11:5:9
First, we find the Total ratio = 11+5+9 = 25
Such that
First part = 11/25 x 5000 = 2,200milliters.
Second Part = 5/25 x 5000=1000milliters.
Third part =9/25 x 5000=1,800milliters.
what is the range of the function f (x)= -1/3 lx-1l-2?
Answers
Answer:
All real values less than or equal to -2 or (infinity, -2].
Step-by-step explanation:
The range of the function is the range of what the output can be. Let’s analyze the equation in parts.
Notice that |x-1| must always be greater than or equal to 0, so we know that 1/3|x-1| also must always be greater than or equal to 1/3*0 = 0.
With the negative, however, -1/3|x-1| must be less than or equal to -1/3*0 = 0.
Finally, we take the -2 into account. -1/3|x-1| - 2 must always be less than or equal to 0-2 = -2.
Therefore, the range is all real values less than or equal to -2, which can be written as (infinity, -2].

From a population of 200,000,000 elements, the standard deviation is known to be 14. A sample of 49 elements is selected. It is determined that the sample mean is 56. The standard error of the mean is
Answers
Answer:
The standard error of the mean = 2
Step-by-step explanation:
Given that:
The standard deviation σ = 14
The sample size n = 49
The sample mean [tex]\overline x[/tex] = 56
The formula for calculating the standard error can be expressed as:
[tex]S.E = \dfrac{\sigma}{\sqrt{n}}[/tex]
[tex]S.E = \dfrac{14}{\sqrt{49}}[/tex]
[tex]S.E = \dfrac{14}{7}[/tex]
S.E = 2
Therefore, the standard error of the mean = 2

sin^2(a+b)-sin^2(a-b)=sin(2a)sin(2b)
Answers
Answer:
Step-by-step explanation:
To prove sin(a+b)*sin(a-b)=cos^2b-cos^2a
we simplify the left side sin(a+b)*sin(a-b) first
sin(a+b) = sin a cos b + cos a sin b
sin(a-b) = sin a cos b - cos a sin b
sin(a+b)*sin(a-b) = (sin a cos b + cos a sin b) x (sin a cos b -cos a sin b)
sin a cos b((sin a cos b + cos a sin b) - cos a sin b (sin a cos b + cos a sin b)
open the bracket
sin a cos b(sin a cos b) + sin a cos b(cos a sin b) -cos a sin b (sin a cos b)+ cos a sin b ( cos a sin b)
sin²a cos²b + sin a cos b cos a sin b - cos a sin b sin a cos b + cos²a sin²b
sin²a cos²b + 0 + cos²a sin²b
sin²a cos²b + cos²a sin²b
sin²a = 1-cos² a
sin²b = 1-cos² b
(1-cos² a)cos² b - cos² a(1-cos² b)
= cos² b - cos² a cos² b - cos² a +cos² a cos² b
choose like terms
cos² b - cos² a - cos² a cos² b + cos² a cos² b = cos² b - cos² a + 0
cos² b - cos² a

Answer:
x=3
Step-by-step explanation:
First start by simplifying the right side which is -5(x-8)+4. Apply the distributive property to have -5x-5*-8+4. Then simplify to -5x+40+4, and then to -5x+44. Now you are left with 14+5x = -5x+44. Move -5x to the left side, which now makes it positive, and do 5x+5x to have 14+10x=44. Now move 14 to the right side and subtract it from 44 to get 10x=30. Now divide both sides by 10 to have x=3.
Answer:
x=-5
Step-by-step explanation:
14 + 5x = -5(x-8)+4
14+5x=-5x+40+4
14+5x=-5x+44
14+10x=44
10x=30
x=3
