Yes as that is the function notation in play. a function of x.
Answer:
16.15 ($) or currency
Step-by-step explanation:
initial cost 850
new price = 8,5 x 1.90 = 16.15
$60 x (100%+15%+7%) = $60 x 122% = $73.20
Start off by writing the equation y = mx - b. Then plug in what you do know
3 = 2(-1) - b (m is the slope and parallel lines have the same slope). Then solve
3 = -2 - b
<u>+2 +2</u>
5 = b
So y = 2x + 5
The ratios that have the same constant of proportionality as Ada's observation 15/9, 30/18
According to the question:
- We are required to select all the ratios that have the same constant of proportionality as Ada's observation.
let y and x represent amount of juice and oranges respectively;
k = 5/3
The ratios equivalent to the constant of proportionality is 15/9, 30/18
