When lines are parallel their slope is the same. So we know the parallel line is y=-5x+b. We plug in the point(-4,-1) to find b.
y=-5x+b
-1=-5(-4)+b
-1=20+b
b=-21
So the equation is y=-5x-21.
Yes.
40% discount means that the discounted price is 60% of the original. After discount, the used book is $18, which is 60% of its original price, x. We form an equation:
18=60/100(x)
1800=60x
x=$ 30
y-4=2(x-6)
y-4=2x-12
y=2x-8
The slope of the line perpendicular must be -1/2. We then have y=-1/2x+b. We plug in the given point (-3,-5) to solve for b.
y=-1/2x+b
-5=-1/2(-3)+b
-5=3/2+b
b=-13/2
So the equation is y=-1/2x-13/2.
5x is 5x/(x/5) times as much as x/5.
5x/(x/5)
=5x*5/x
=25 times
Then x/5 is 1/25 as much as 5x.
1/25x100=4%
haha it's fine.
Hi, how's your day been :)
If Ali won 5 games, that means Veli and Selami lost 5 games combined. We know Veli lost 4 games so Selami lost 1 game. If Ali lost 3 games then Veli and Ali won 3 games in total. Veli won 1 game so Selami won 2 games.
-150x>=-2400
150x<=2400
x<=16
-336>=-21y
336<=21y
16<=y
y>=16
x is less than y.
Dividimos 21 por 2.5 para obtener 8.4.
