In the first Lesson Activity, you derived an equation to model a car wash. The equation is y = 5x – 75. In this activity, you will graph this equation. Is it possible to graph the line that represents this equation by using two points found in the previous Lesson Activity, (15, 0) and (0, -75)? Explain your answer.

9514 1404 393

  yes. The graph goes through those two points

Step-by-step explanation:

The equation can be graphed by plotting the two given points and drawing a line through them. Such a graph is shown in the attachment.

rick has $1400 and sally has $1500

step-by-step explanation:

to find amount of money rick has after 10 years :

principal = $1000 , time = 10 years , rate = 4% annually

to find amount of money sally has after 10 years :

her friend gives to pay her $50 per year, therefore money she has after 10 years = 50 × 10 = $500

also, sally gets $1000 after 10 years,

therefore, total amount of money sally has after 10 years = 500 + 1000 = $1500

so, after 10 years : rick has $1400 and sally has $1500
