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
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 :)

x = 65
y = 0.75(65) + 5
y = 48.75 + 5
y = 53.75

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].
