HACTEHA [7]3 years ago
6 0

Answer:

Assuming you want the amount of pens that Mai has left, the answer is 0.

Step-by-step explanation:

Mai has 8 packs of pens. She gives 5 away to Ervin and 3 away to Sara. In total, she gives away all 8 packs (because 5+3=8).

She started with 8, and gave away 8. This resulted in her having 0 packs left (because 8-8=0).

I hope this helps!

A laptop computer is purchased for 2500 . After each year, the resale value decreases by 25% . What will the resale value be aft
balandron [24]

Answer: the resale value would be $791 after 4 years

Step-by-step explanation:

We would apply the formula for exponential decay which is expressed as

y = b(1 - r)^x

Where

y represents the value of the laptop computer after x years.

x represents the number of years.

b represents the initial value of the laptop computer.

r represents rate of decay.

From the information given,

P = $2500

x = 4

r = 25% = 25/100 = 0.25

Therefore,

y = 2500(1 - 0.25)^4

y = 2500(0.75)^4

y = $791

Determine the equation
sergejj [24]

Answer:

y=\frac{3}{4} x-\frac{5}{4}

Step-by-step explanation:

two points on the line are

(-1, -2)

(-5, -5)

The slope:

m=\frac{-2-(-5)}{-1-(-5)} =\frac{-2+5}{-1+5} =\frac{3}{4}

The equation:

with (-1,-2)

y-(-2)=\frac{3}{4} (x-(-1))

y+2=\frac{3}{4} x+\frac{3}{4}

y=\frac{3}{4} x+\frac{3}{4} -\frac{8}{4}

y=\frac{3}{4} x-\frac{5}{4}

Hope this helps
