X=3
Y=5
0.30 x 5 = 1.5
1.50 x 3 = 4.5
1.5 + 4.5 = 6
4x12 = 48 and4x6 = 24 so
Add 48 and 24 =72
Answer:
$74.97
Step-by-step explanation:
Cost of skateboard = $79.43
Less 12 % = 0.12 × 79.43 = <u> -9.53
</u>
Sale price = 69.90
Plus sales tax = 0.0725 × 69.90 = <u> +5.07
</u>
Total cost = $74.97
For this you can write equations for your business and your friend's. For your's it would be y=10x-25 and for your friend's it would be y=13x-55. Now at this point you can just plug in numbers until you match up. Your answer would be 10, if you want to you can plug it in to check.
Answer:
We can see that as the endpoints of the intervals increase, the average rate of change for a square root function decrease
Step-by-step explanation:
Take for example the following intervals:
- interval: 0 - 1, average rate of change: √1 - √0 = 1
- interval: 1 - 2, average rate of change: √2 - 1 = 0.414
- interval: 2 - 3, average rate of change: √3 - √2 = 0.317
- interval: 3 - 4, average rate of change: 2 - √3 = 0.267
