Answer:
y=1/5x-39/5
Step-by-step explanation:
y=mx+b (slope y intercept formula)
y=1/5x+b
take (-6,-9) and put in appropiate places
-9= -6/5+b
*multiply lhs and rhs by 5
-45= -6+5b
-45+6=5b
-39=5b
-5b=39
b=39/-5
y=1/5x-39/5

Call the number of hardcover and paperback books, h and p.
Thus
h + p = 8 and the value equation is
4h + 2p = 26
Now multiply the top one by four and subtract from the second one...we get
4h + 2p = 26
-(4h + 4p = 32)
----------------
-2p = -6
p = 3 so that
h = 5 x + y = 8, (1)
4x + 2y = 26, (2)
where x and y are the numbers of hardcover and softcover books respectively.
To solve, multiply the equation (1) by 2 (both sides) and then distract it from the equation (2). You will get
4x - 2x = 26 - 16, or
2x = 10, or x = 5 - the number of hardcover books purchased.
Then from the equation (1) you get y = 3.
Check. 4*x + 2*3 = 4*5 + 2*3 = 26. OK.
Answer:
The answer to your question is 57.3 kg
Step-by-step explanation:
a)

= 
= 6.36 X stones
b) Weight = 6.36 (x)
