Answer:
A used car has a value of $15,250 when it is purchased in 2012. The value of the car decreases at a rate of 7.5% per year.
Write an exponential function that models the value of the car, y, over x years.
To the nearest cent, what will be the value of the car after eight years?
Step-by-step explanation:
The correct answer is A: x=2 and y=-3. Either method would work, but for example, let's use elimination. If you multiply the second equation by 5, you get: 10x +5y = 5. When you add both equations, you can then cross out both y terms. You are left with one equation that reads: 13x=26. Solving for x gives you 2. You can substitute 2 in for x in either equation and you will receive -3 for your y value.
Answer:
10 large and 10 small buckets in total.
214 clams in total.
You would have to multiply 25 on both sides because it is being divided. 4 times 25 is 100.
Answer:
6/1 square feet per hour. Jeff can paint faster.
Step-by-step explanation:
So, to get Jeff's square feet to 60 minutes, you do 30x2= 60. So, you do that to 28. 28x2= 56. 56/1 is greater then 50/1. So 56-50= 6. Jeff can paint 6 square feet per hour, greater than Angela.
Hope this helped!
