Answer: Scale factor of -1/2
Step-by-step explanation:
B=A*(-2)
A=B/(-2)
A=-(B/2)
A=B*(-1/2)
Scale factor of -1/2
Answer: 5x - 2
Step-by-step explanation:
So area is length*width, we have the area and length which is 5x^2 + 43x - 18 and x + 9. So we need to divide. First the x, what times x is 5x^2? 5x, x*x is x squared. Then we need to apply the 5x to 9. 5x*9 is 45x, and we can’t do anything to the 18 because 18/5 is a decimal. After that we subtract the new area with the old one. 5x^2 + 43x - 18 minus 5x^2 + 45x which is -2x - 18. Now we divide the -18 with 9 which is -2. Remember the 5x we had from using the x? We put that and -2 together which is 5x-2, and that’s your width. Hope this helped!
40 hours. Armando reads 20 pages per 4 hours. 20*10 would get to 200 which is the total amount of pages. So you would multiply the amount of hours by the same amount 4*10 which = 40 hours total.
Answer:
The slope of line for given points is 
Step-by-step explanation:
Given points of line as :
A = ( - 7 , 15 ) i, e
= - 7 ,
= 15
B = ( 10 , 27 ) i.e
= 10 ,
= 27
Let The slope of line be m
So , The slope with two points is given as equation
m = 
Or, m = 
Or, m = 
Hence The slope of line for given points is
