Answer:
m = -3m+3n/-2b
Step-by-step explanation:
Slope is expressed as;
m = y2-y1/x2-x1
Given the coordinates (a+b,4m-n) and (a-b,m+2n)
m = (m+2n)-(4m-n)/(a-b)-(a+b)
m = m+2n-4m+n/a-b-a-b
m = m-4m+2n+n/a-a-b-b
m = -3m+3n/-2b
Hence the required slope is m = -3m+3n/-2b
Answer:
This is a 10 percent increase
Step-by-step explanation:
Last week he spent 10 hours
This week 11 hours
percent increase = (new - original )/original * 100 percent
= (11-10)/10 * 100 percent
= 1/10 * 100 percent
= 10%
This is a 10 percent increase

145÷7.25 = 20
Step-by-step explanation:
This is a simple division of numbers with decimals.
Here we have dividend ( the number to be divided) (or numerator) = 145
and divisor (the number which divides dividend) (or denominator)= 7.25
Now, in case of decimals in denominator, we add number of zeroes in numerator equal to number of digits after decimal point in denominator, and thus the decimal point gets removed. So, this gives us 14500÷725, which by simple calculation is equal to 20.
