In ax+by=c form
slope=-a/b
y intercept is when x=0
sloope of 2x-5y=12 is -2/-5=2/5
y intercept of 4y+24=5x
4y+24=5(0)
4y+24=0
4y=-24
y=-6
y int=-6
y=mx+b
m=slope
b=y intercept
y=2/5x-6
answer is 2nd optoin
45 divided by 4= $9 per bag and 24divided by 2 = $12 per bag pet smart has the lower unit price
Answer:
16. $ 4100
17. y = 10000 - 750x
Step-by-step explanation:
16)
As initial value is $ 5000, and salvage value is $ 500. That means in 5 years value decreased by 5000-500 = 4500 so ,
in 5 year value decreased = 4500
in 1 year value decreased = 4500/5 = 900
so per year 900 $ gets decreased from original price. So equation can be given as
V = 5000 - 900y
where V is value of a vehicle and y is number of year
So after 1 year value would be
V = 5000 - 900 x 1 = 5000 -900 = 4100 $
17)
initial cost of car = $ 10000
per year amount decreases by = $ 750
then equation can be given as
y = 10000 - 750x
where x is number of year and y is cost of car after x year.
5000 x (1-0.10)^2
5000 x 0.90^2
5000 * 0.81
it is valued at 4,050 after 2 years
