Hello,
1) Finding the slope of the line passing throught the 2 points:
m=(-8-6)/(7-2)=-14/5.
A perpendicular line has a slope of -1/m=5/14
So the line searched has for equation:
y+1=(x-2)*5/14
or 10x-28y+73=0
Answer:
none is a solution...the solution.is -3
Answer:
10.
Step-by-step explanation:
I am assuming that z is a whole number.
160z = x^2
z = x^2/ 160.
160 = 2*2*2*2*2*5
To make this a perfect square we multiply by 2 * 5
- this gives us 1600.
z = 1600/160 = 10.
Answer:
The publisher must sell 4,632 books in order to break even(total sold equals production costs).
Step-by-step explanation:
So the bookstores are really making $24-10.25 in profit off of each book. This equals $13.75 profit for every book sold.
So you set up an equation:
13.75x=$63,690
x=63690/13.75
x=4632
Answer: x = -5
Step-by-step explanation:
Given the equation: 3(x+1)=2(x-1)
Open the brackets
3x + 3 = 2x -2
Combine like terms
3x - 2x = -2 -3
x = -5
I hope this helps, please mark as brainliest answer.
