Uncorrectly:5 => -5
unanswered:2 =>0 points
20x4=80 points in total(only correct awnsers)
=>20-5+2=13 correct awnsers
13x4=52
52-5=47
It will be nice if you give me brainliest. Good luck!
No solution means that the lines are paralell and have differnt y intercepts
paralell means has same slope
y=mx+b
m=slope
b=yint
given equation is
y=-3x+5
slope=-3
yint=5
paralell so
y=-3x+b
wher b is any number except 5
example
y=-3x+4
y=-3x+√3
y=-3x-π
basically
m=-3
b=any number except 5
The granola summer buys used to cost $6.00 per pound but it has been marked up %15 Question: How much did it cost summer to buy 2.6 pounds of granola at the old price.=> previous price of granola = 6.00 dollars per pound=> marked up 15% = 15% /100% = .15 solve:=> 6 * .15 = .9=> 6 + .9 = 6.9 dollars per poundNow, you want to buy 2.6 pounds=> 6.9 * 2.6 = 17.94 dollars
15 - 8
8 + 2 is 10, so there are 5 leftover. 2 + 5 is 7, so 8 + 7 is 15.
