Answer:
Step-by-step explanation:

5x + 20 because rise over run 5 over 1 so its 5x and 20 is on the y intercept line
Step-by-step explanation:
G(n) + f(n)
3n + 1 + 4n - 3
7n - 2
40% off means you are paying 60% of the original price ( 100% - 40% = 60%
Multiply the price of the coat by 60%:
65.00 x 0.60 = 39.00 ( sale price)
Now multiply the sale price by 1.05 ( price of coat plus tax rate) to get the final cost:
39.00 x 1.05 = 40.95
The final price is $40.95
I believe it’s 2 because rise/run and 14/7 = 2
