1/7 I don't know if this is subtract or not but I subtracted
Add 5 to both sides. Then 8x > -6, and x > -3/4 (answer)
Step-by-step explanation:
solution..
(0,5)=(x1,y1)
(-3,4)= (X2,y2)
now,
distance (d)^2=(x2-x1)^2+(y2-y1)^2
Answer:
William must make more than 1805 copies.
Step-by-step explanation:
Cost of photocopier and supplies = $162.50.
This will allow him to make copies for $0.12 each. This rate is cheaper than that of the photocopy store that charges $0.21 for each copy.
To determine the number of copies William must make before his total cost is less than getting copies made at the photocopy store,
Let x = the number of copies he needs to make.
0.12x +162.5 should be lease than 0.21x
Replacing the inequality sign(lesser than) with equal to,
0.12x +162.5 = 0.21x
0.09x = 162.5
x = 1805.55
Approximately,x = 1806
So William must make more than 1805 copies.
