150 - 8d = 175 - 10d
-8d + 10d = 175 - 150
2d = 25
d = 25/2
d = 12.5...so each dvd costs 12.50

150 - 8(12.5) = 150 - 100 = 50
175 - 10(12.5) = 175 - 125 = 50

so they will each have 50 bucks left on their card

At age 16, Estelle weighed 110lbs.
Cloud [144]

Answer:

Her weight is increase by 18 lbs over past five years and the slope is 3.6 lbs per year.

Step-by-step explanation:

Given information: Estelle weight is

At age 16 =  110 lbs

At age 21 = 128 ibs

Increase in her weight over the past 5 years is the difference of weight at age 21 and at age 16.

Increase in her weight over the past 5 years = 128 - 110 = 18

Her weight is increase by 18 lbs over past five years.

Let x=age and y=weight, then the weight function passes through the points (16,110) and (21,128).

If a line passes through two points (x_1,y_1) and (x_2,y_2),  then the slope of the line is

m=\frac{y_2-y_1}{x_2-x_1}

Using the above formula we get

m=\frac{128-110}{21-16}

m=\frac{18}{5}

m=3.6

Therefore the slope is 3.6 lbs per year.
