Answer:
if you mean y=3x, then yes
Step-by-step explanation:
solution:
substitute s by -3, we obtain
y= 3 (-3)
y= -9
So, if x= - 3 then it's y= - 9
Answer:

Answer:
a. $33.15
b. $21.75
c. $31.50
Step-by-step explanation:
To solve multiply the price of each video game by the percent you pay. To find this, convert the percent off to a decimal and subtract it from 1.
a. 15%=0.15 and you pay 1-0.15 = 0.85
0.85(39)= 33.15
b.25%=0.25 and you pay 1-0.25 = 0.75
0.75(29)= 21.75
c.30%=0.30 and you pay 1-0.30 = 0.7
0.7(45)= 31.50
